Exercise vs. Diet: What Works Best for Losing Weight?
Did you know diet is key for losing weight, 70% of the time? Health and fitness manager Colleen Alrutz says so. Diet controls calorie intake and is crucial for starting weight loss. Exercise helps keep the weight off and boosts health and fitness.
To lose one pound a week, you need to burn 3,500 calories. That's about 500 calories a day. Walking for an hour at 3.5 mph burns 391 calories. But, cutting out one 20-ounce soda saves 240 calories. This shows diet and exercise both matter for calorie control.
Exercise alone isn't a fast solution. The American Heart Association suggests 150 minutes of moderate exercise weekly for health. But, a healthy diet and regular exercise together lead to lasting weight loss. For example, skipping a venti Green Tea Frappuccino saves about 520 calories, helping with daily calorie deficit.
How Exercise Affects Weight Loss: A Comprehensive Guide
To understand the impact of exercise for weight loss, we need to look at how it affects our body. It's not just about burning calories. It's about making our metabolism better and improving our health.
The Science Behind Exercise and Calorie Burn
Exercise helps us lose weight by burning calories. The Centers for Disease Control and Prevention (CDC) says adults need 150 minutes of moderate exercise weekly. Activities like walking, cycling, and swimming are great for burning fat.
But, don't forget about strength training. It helps build muscle. This means you burn more calories, even when you're not moving.
Types of Exercises for Maximum Fat Loss
There are many exercises that help burn calories for fat loss. Here are some examples for a 160-pound person:
- Aerobics, low-impact: 365 calories/hour
- Swimming laps (light or moderate): 423 calories/hour
- Cycling (
- Running (5 mph): 606 calories/hour
- Hiking: 438 calories/hour
Strength training is key, done at least two times a week. It builds muscle, which helps burn more calories. Mixing aerobic exercises with strength training is the best way to lose weight.
Remember, everyone reacts differently to exercise. Things like genetics, age, and health can affect how well you lose fat. Always talk to a doctor before starting a new workout plan, especially if you're new to exercise or have health issues.
This balanced approach makes sure exercise works well with a healthy diet. It's a better way to lose weight and keep it off.
Overview of Popular Weight Loss Drugs and Their Efficacy
Before 2012, there were only a few approved weight loss drugs. Phentermine and orlistat were the main choices. These drugs work in different ways, like reducing hunger or blocking fat absorption.
New drugs like Wegovy (semaglutide) and Ozempic have become popular. Their use has increased a lot since 2022. This shows they are seen as effective in losing weight.
Zepbound was approved in November 2023 for people with a BMI of 30 or higher. Wegovy is approved for those aged 12 and older with a BMI of ≥30 or ≥27 with health issues. Wegovy's dose increases to 2.4 mg over 16 to 20 weeks, helping with weight loss.
Here's a look at how well some diet pills work:
| Medication | Average Weight Loss |
|---|---|
| Phentermine | 5% of body weight |
| Phentermine-topiramate combination | 5-10% of body weight |
| Naltrexone-bupropion | 5-10% of body weight |
| Orlistat | 5% of body weight |
| Plenity | 9% of body weight |
| Liraglutide (Saxenda) | 5-10% of body weight |
| Semaglutide | 14.9% (in a major study) |
The weight loss from these drugs varies, from 5% to almost 15%. Semaglutide has shown the most promise, with one study showing a 14.9% weight loss.
Most of these drugs are for people with a BMI of 30 or higher. Or for those with a BMI of 27 and health issues. It's important to use these drugs with a doctor's guidance. Side effects can happen, so they should be part of a bigger plan that includes lifestyle changes.
Top Benefits of Regular Exercise Beyond Weight Loss
Regular exercise offers many benefits beyond just losing weight. It boosts both mental and heart health, leading to a better life. Exercise is key to a healthy lifestyle, with many advantages.
Improving Mental Health
Exercise greatly improves mental health. It reduces anxiety and depression. It also boosts mood through endorphins, which are natural mood lifters.
A 2019 review showed that just 10–30 minutes of exercise can lift your mood. It also boosts self-esteem and brain function. Stopping exercise can lead to more depression and anxiety, a 2017 review found.
Regular exercise also helps you sleep better. Better sleep means less stress and better mental health. So, exercise is a great way to improve your mental well-being.
Enhancing Cardiovascular Health
Exercise is vital for heart health. It raises good cholesterol and lowers bad cholesterol. This reduces the risk of heart disease.
The U.S. Department of Health and Human Services suggests 150 minutes of moderate activity weekly. More exercise, like 300 minutes, offers even more benefits. Exercise also manages blood pressure and improves heart function.
It reduces the risk of diseases like diabetes and cancer. Strength training twice a week also builds muscle, which is good for the heart and metabolism.
Here's a table with key exercise recommendations and statistics:
| Aspect | Recommendation/Statistic |
|---|---|
| Moderate Aerobic Activity | At least 150 minutes per week |
| Vigorous Aerobic Activity | At least 75 minutes per week |
| Strength Training | Two times a week |
| Mental Health Benefits | Reduces anxiety, depression, improves mood |
| Cardiovascular Health Benefits | Increases HDL, lowers triglycerides, reduces chronic disease risk |
Adding exercise to your life is good for more than just weight loss. It's crucial for mental and heart health. Regular exercise brings many health benefits.
Diet vs. Exercise: Which is More Effective for Weight Loss?
Understanding how diet and exercise help with weight loss is key. Studies show that changing what you eat can lead to quicker and more noticeable weight loss. On the other hand, exercise keeps you fit and healthy.
A study with 145 overweight women aged 40–60 looked at diet and exercise together for 8 weeks:
- BMI reduction: -1.3 kg/m²
- Body fat reduction: -2.9%
- Increase in lean body mass: +1.1
- VO2 max improvement: +4.8
- Improvement in body image score: +1.02
The study found big improvements in both diet and exercise groups. These were better than the control group (p
Another study compared different weight loss programs:
| Intervention | Mean Weight Loss (3-6 months) | Mean Weight Loss (12 months) |
|---|---|---|
| Combined Diet & Exercise (BWMPs) | –0.62 kg | –1.72 kg |
| Diet-Only | No comparison provided | No comparison provided |
| Physical Activity-Only | –5.33 kg | –6.29 kg |
This study shows diet is key for quick weight loss. But, exercise is vital for keeping muscle, heart health, and mental well-being.
Worldwide, too many people are overweight or obese, with over 1.9 billion adults in 2016. Being overweight raises the risk of serious diseases, costing health systems a lot.
How well diet and exercise work can depend on personal needs and lifestyle. But, combining both is usually the best way to lose and keep off weight.
Understanding Anti-Obesity Medications: What You Need to Know
Anti-obesity medications are getting more attention as obesity rates in the U.S. hit over 40%. Drugs like Ozempic, Wegovy, and Mounjaro help manage weight. They work by mimicking gut hormones, which increases insulin release and slows down stomach emptying.
Types of Anti-Obesity Drugs
There are many types of anti-obesity medications out there. Some well-known ones include:
- Orlistat: Reduces fat absorption in the intestines.
- Phentermine: A stimulant that suppresses appetite.
- Ozempic, Wegovy, and Mounjaro: Mimic gut hormones to regulate insulin and digestion.
Patients on Wegovy can lose 15% to 16% of their body weight. Those on Mounjaro might lose 20% to 22%. New drugs in development could lead to weight loss of 24% to 25%.
Potential Side Effects and Considerations
Anti-obesity medications can be very effective but come with potential medication side effects. Common issues include:
| Medication | Common Side Effects |
|---|---|
| Orlistat | Gastrointestinal issues, such as oily stools |
| Phentermine | Increased heart rate, high blood pressure |
| Ozempic, Wegovy, Mounjaro | Nausea, diarrhea, constipation |
It's important to talk to a healthcare provider before starting any medication. A good plan should include healthy eating and regular exercise.
Studies show success in weight loss is losing at least 5% of body weight in the first three months. For example, a 200-pound person losing 20 pounds has a big impact. But, stopping these medications can lead to weight gain over time.
Combining anti-obesity medications with lifestyle changes is key. This includes 150 minutes of moderate exercise and two days of resistance training each week. This approach helps manage weight in a lasting way.
Effective Lifestyle Changes to Support Weight Loss
Effective weight management often requires sustainable lifestyle changes for weight loss. One key step is to increase physical activity. Aim for at least 150 minutes a week of moderate activity, like brisk walking. Or, do 75 minutes of vigorous activity, like running.
Incorporate daily activities into your routine. Cleaning, shopping, mowing, and gardening can help. They contribute to your overall physical activity and support long-term health.
Adopting healthy habits in your diet is also crucial. The Mayo Clinic Diet suggests eating healthier, lower-calorie meals. Adults should aim to cut down on calorie intake from foods and drinks.
Limit added sugars and saturated fats to less than 10% of daily calories. Stay under 2,300 milligrams of sodium daily. Eating at least 2.5 cups of fruits and vegetables daily boosts both weight management and health.
It's also important to engage in muscle-strengthening activities. Do these on at least two days a week, focusing on all major muscle groups. Studies show that regular physical activity increases the chance of keeping weight off by 50%.
Combining diet and exercise in a personalized plan can greatly improve weight loss success. Such programs can lead to an 80% increase in success rates.
Mental habits also matter. Mindful eating can cut binge eating episodes by 52%, helping with weight management. Plus, a consistent exercise routine can boost metabolism by 15%. This supports weight loss and maintenance.
Sustainable Long-Term Weight Loss Strategies
For lasting success in weight loss, it's key to eat healthy and stay active. Building strong habits, like planning meals and working out regularly, helps reach and keep weight loss goals.
The Role of Consistency and Habit Formation
Being consistent is key to keeping weight off for good. Studies show that sticking to healthy habits, like regular exercise and meal plans, leads to better weight control. A study from the Midwest Exercise Trial 2 found that regular exercise helped people lose a lot of weight.
The National Weight Control Registry also found that 94% of successful losers included exercise in their plans. This shows how important it is to make exercise a regular part of your life.
Balancing Diet and Exercise for the Long Haul
It's important to find a balance between what you eat and how much you exercise. Studies, like one from the University of Cincinnati Medical Center, show diet and exercise together lead to more weight loss than diet alone. Aim for 60 minutes of activity daily and follow a diet that helps you lose weight without missing out on nutrients.
Also, mixing aerobic and resistance training helps keep muscle mass and improves health. The American College of Sports Medicine and ADA suggest 60 minutes of activity daily for those losing weight through exercise. Keeping a balanced diet and regular exercise routine are key to lasting weight loss success.
How Metabolism Influences Your Weight Loss Journey
Metabolism plays a key role in weight loss. It's all about the body's chemical processes that keep us alive. These processes affect how fast we burn calories. Knowing how to boost your metabolism can help manage your weight.
Factors Affecting Metabolism
Many things can change your metabolic rate. Genetics are a big factor, with hundreds of genes linked to weight gain. Age also matters, as muscle loss slows down metabolism. Men generally have faster metabolisms than women due to more muscle and less fat.
Metabolic compensation is another factor. It's when your body slows down to keep fat when you eat fewer calories. Your basal metabolic rate (BMR) is also important. It's the calories your body burns at rest, and it's influenced by muscle mass.
Ways to Boost Metabolism Naturally
There are natural ways to boost your metabolism. Building muscle through strength training is very effective. It burns more calories, even when you're not moving. Drinking plenty of water also helps, as dehydration can slow down metabolism.
Eating protein-rich foods can also help. They increase the energy needed to digest and process nutrients. Regular exercise, as recommended by the Physical Activity Guidelines for Americans, is another key factor. It helps burn more calories.
Lastly, nonexercise activity thermogenesis (NEAT) is important too. It includes activities like walking and fidgeting. These can burn an extra 100 to 800 calories a day.
While some supplements claim to boost metabolism, they often don't work. Instead, stick to proven and safe methods to help your weight loss journey.
The Benefits of Combining Exercise with Weight Loss Medications
Using both exercise and medication for weight loss is a smart move. It helps you lose weight faster and improves your health. This mix of exercise and medication works together to help you reach your weight loss goals.
Studies show that GLP-1 medications, like semaglutide and tirzepatide, help a lot when you exercise regularly. The SURMONT-1 trial found a 20.9% weight loss over 72 weeks. This was with participants getting lifestyle counseling too.
One big plus of exercising with medication is keeping muscle mass. A study in the Journal of Obesity found that resistance training helps keep muscle. This is key for keeping weight off for good.
Exercise also makes your body better at using glucose and lowers blood sugar. This is great for people taking weight loss meds. It helps keep your body balanced and healthy.
Exercise and medication also help your heart. They lower blood pressure and cholesterol, reducing heart disease risk. Plus, exercise helps your mind, easing depression and anxiety that often come with being overweight.
For the best weight loss, mix exercise, healthy eating, and medication. This combo boosts weight loss and improves your lifestyle. Guidelines suggest 150 minutes of aerobic activity and muscle-strengthening twice a week. This fits well with medication plans.
| Benefits | Outcome | Study/Source |
|---|---|---|
| Weight Reduction with GLP-1 Medications | 20.9% over 72 weeks | SURMONT-1 Trial |
| Retention of Muscle Mass | Resistance training importance | Journal of Obesity |
| Metabolic Health Improvement | Better glucose use, lower blood sugar | Journal of Applied Physiology |
| Cardiovascular Health Benefits | Reduced blood pressure, cholesterol | Various Sources |
| Mental Health Enhancement | Reduction in depression and anxiety | Various Sources |
Combining exercise with medication is a smart way to lose weight and get healthier. Always talk to a doctor to make sure it's right for you. This way, you get the most benefits safely.
Why HIIT is Effective for Weight Loss
High-intensity interval training (HIIT) is gaining popularity for its weight loss and fitness benefits. It involves short, intense workouts followed by rest. This method burns more calories in less time, making it efficient for many.
Understanding High-Intensity Interval Training
HIIT workouts last from 10 to 30 minutes and burn 25-30% more calories than traditional exercises. People doing HIIT exercise for only one-third of the time of jogging or biking but still burn similar calories. It also raises metabolic rates for hours after exercise, beating out jogging and weight training.
- A review of 13 experiments involving 424 adults with overweight or obesity found that both HIIT and moderate-intensity exercise effectively reduce body fat and waist circumference.
- HIIT may be particularly effective for fat loss in overweight or obese individuals due to its intense calorie-burning potential.
- Research indicates that HIIT can improve oxygen consumption by 9% over 20-minute workouts completed four days a week for five weeks.
- HIIT can reduce blood pressure just as effectively as traditional endurance training, particularly in individuals with high blood pressure and obesity.
Benefits Compared to Moderate Exercise
HIIT has many advantages of HIIT over moderate exercise. It burns more calories and boosts metabolic and cardiovascular health more efficiently. A study showed HIIT lowered blood pressure with just three sessions a week, compared to endurance training.
HIIT also improves blood sugar and insulin resistance. This is good for both healthy people and those at risk for type 2 diabetes.
- HIIT enhances performance in both anaerobic and aerobic activities with just a few short sessions per week.
- In a study involving 44 obese subjects, the HIIT group lost an average of 5.7 kg over 12 weeks, comparable to the 6 kg lost by the moderate-intensity continuous training (MICT) group.
- HIIT also resulted in a greater improvement in oxygen consumption (VO2peak), with an increase of 461.6 mL compared to 170.5 mL in the MICT group.
In conclusion, high-intensity interval training (HIIT) offers significant benefits for weight loss and fitness. Adding HIIT to your routine can lead to impressive health improvements efficiently and effectively.
The Importance of Resistance Training in Weight Management
Resistance training is key for managing weight. It builds muscle, which burns more calories than fat. This boosts your metabolic rate, helping with weight control.
Studies show resistance training helps keep lean mass when losing weight. A review found it reduces lean mass loss by 0.8 kg.
Strength training isn't just about lifting weights. It includes many exercises that build muscle and improve fitness. Regularly doing it can cut body fat and increase lean muscle, helping with weight management.
Twelve systematic reviews and meta-analyses looked at 149 original studies. Here are some key findings:
| Area of Focus | Number of Studies Assessing | Key Findings |
|---|---|---|
| Weight Loss | 105 | MDs ranging from −1.5 kg to −3.5 kg |
| Fat Loss | 94 | MDs ranging from −1.3 kg to −2.6 kg |
| Lean Mass/Fat-Free Mass Loss | 38 | Reduction in lean mass loss by 0.8 kg |
| Visceral Adipose Tissue Loss | 37 | SMDs ranging from −0.33 to −0.56 |
The analysis started with 3320 articles, narrowing to 123 reviews. These 12 systematic reviews were included. They showed exercise, like resistance training, is crucial for weight loss.
Regular resistance training helps lose fat and weight right away. It also improves your metabolic rate and prevents muscle loss in the long run.
How Behavioral Therapy Can Enhance Your Weight Loss Efforts
Behavioral therapy for weight loss is a powerful tool. It tackles the mental blocks that stop us from eating well and exercising regularly. This approach helps change our behaviors and thoughts.
Psychological Barriers to Weight Loss
Knowing the mental obstacles to losing weight is key. About 25% of people in weight loss programs have depression. Stress, low self-esteem, and emotional eating are also big challenges. Behavioral therapy helps tackle these issues by teaching coping skills and setting achievable goals.
Techniques Used in Behavioral Therapy
Behavioral therapy uses many techniques to help with weight loss. Some important methods include:
- Setting Realistic Goals: Making small changes, like eating smaller portions, can greatly improve weight management.
- Self-Monitoring: Keeping a food diary can double the chances of losing and keeping off weight.
- Group Therapy: About 70% of people in group sessions do better than those in one-on-one therapy.
- Consistent Meetings: Starting with weekly meetings, then moving to bi-weekly or monthly, helps maintain progress.
- Coping Strategies: Learning how to handle situations that might lead to unhealthy eating is crucial for lasting success.
Being overweight increases the risk of many health problems. These include diabetes, arthritis, high blood pressure, heart disease, and some cancers. Behavioral therapy can greatly improve both physical and mental health.
About 30% of people who get intensive behavioral therapy keep the weight off long-term. Staying in touch with a support group or therapist can cut the risk of gaining weight back by about 60%. This makes behavioral therapy a key strategy for lasting change.
Understanding GLP-1 Receptor Agonists: A New Era in Weight Loss
GLP-1 receptor agonists are a new way to lose weight. They make you feel full, which helps you eat less and control your blood sugar. This makes it easier to manage your weight.
Studies have shown how well these drugs work. For example, semaglutide helped people lose 12% more weight than those who took a placebo. Another drug, liraglutide, kept people 5.1 kg lighter even after treatment stopped.
A study found that people lost 13.1 kg in eight weeks on a low-calorie diet. Then, using GLP-1 receptor agonists for a year helped them keep the weight off.
| Weight Loss Maintenance | Odds Ratio (OR) | 95% CI Range |
|---|---|---|
| Combined Treatment (Exercise + Liraglutide) | 7.2 | 2.4; 21.3 |
| Liraglutide Alone | 4.2 | 1.6; 10.8 |
| Supervised Exercise Alone | 3.7 | 1.2; 11.1 |
But, sticking with these drugs for a long time is hard. Up to 50% stop using them within a year. Also, many people gain back most of the weight they lost after stopping treatment.
Still, the benefits of using semaglutide are clear. People lost an average of 7.9% of their body weight after 68 weeks. A newer drug, tirzepatide, has even better results, with an 18% weight loss after 78 weeks.
Tips for Improving Exercise Adherence for Better Results
Sticking to your exercise plan can really boost your fitness. Here are some tips to help you stay on track:
- Set Attainable Goals: Make sure your goals are realistic and achievable. Break down big goals into smaller steps to see your progress.
- Find Enjoyable Workouts: Choose exercises you like. Whether it's yoga, running, or team sports, picking something fun can keep you motivated.
- Schedule Regular Exercise Times: Being consistent is crucial. Set specific times for workouts to make it a habit.
- Track Progress: Keeping a record of your achievements can be a great motivator. Use apps, journals, or wearables to track your progress and stay focused on your goals.
Studies show that sticking to exercise can lead to better health:
| Study Aspect | Outcome |
|---|---|
| National Weight Control Registry (NWCR) | Over 90% of participants reported weight loss through food restriction and physical activity. |
| NIH Report (1998 Review of 24 RCTs) | Evaluated effects of physical activity, recommending 3-7 sessions per week, 30-60 minutes per session. |
| Randomized Study on Intense Activity | Participants with intense activity (~2500 kcal/week) maintained 50% larger weight loss after 18 months. |
| Prevalence of Weight Problems (NZ Study) | 60% of patients were overweight. |
| Overall Adherence Rates | Martial arts classes showed higher adherence than aerobics classes. A 94% adherence rate was noted in a 16 ½ week aerobic dance class. |
Consistent exercise can change your life for the better. It leads to improved health and fitness.
The Psychological Impact of Dieting on Weight Loss
Looking into the psychological effects of dieting shows that losing weight is tough on the mind and body. People often aim for a healthier body but face big emotional and mental challenges. This part talks about how dieting affects our minds and how to deal with these issues.
Dealing with Food Cravings
One big challenge of dieting is handling cravings. These cravings are not just about hunger; they're also linked to our emotions and thoughts. Studies by Ancel Keys found that when people were on a semi-starvation diet, food was all they could think about.
Good ways to handle cravings include:
- Eating balanced meals to meet all nutritional needs, which can cut down cravings.
- Having occasional treats to avoid feeling deprived and prevent binge eating.
- Finding other ways to deal with emotional triggers, like hobbies or exercise.
Also, eating foods high in fiber and lean proteins can keep you full longer. This helps avoid unhealthy snacking. Remember, keeping up with a diet long-term depends on managing these mental challenges well.
Avoiding Diet Burnout
It's also key to avoid diet burnout. Strict diets can make people feel overwhelmed and discouraged. This can lead to anxiety, depression, and quitting the diet. Studies by Ancel Keys showed that many men felt more anxious and isolated while dieting.
To stay on track and avoid burnout, try these tips:
- Set realistic goals to keep expectations in check and progress steady.
- Focus on making lasting lifestyle changes instead of quick fixes. This makes dieting more enjoyable and sustainable.
- Stay active to boost mood and reduce stress, helping to fight off negative dieting feelings.
Adding flexibility, like allowing for treats now and then, can help stick to the diet. This makes it a part of your lifestyle, not just a quick fix.
In summary, dieting comes with its own set of mental hurdles, but they can be overcome. By understanding and tackling the psychological effects of dieting, managing cravings, and avoiding burnout, people can increase their chances of lasting success in weight loss.
Are Nutritional Supplements Effective for Weight Loss?
Nutritional supplements for weight loss are popular, with Americans spending over $2 billion a year. But, their effectiveness varies, and scientific support is often lacking.
Research shows mixed results for popular supplements. For instance, chromium might help with weight loss a bit. But, raspberry ketones have little to no proof of safety or effectiveness. Green tea is safe to drink, but its extract pills could harm the liver.
Despite the huge market, little scientific proof exists to confirm the long-term benefits of nutritional supplements for weight loss. The U.S. Government Accountability Office says there's "little known" about their actual effectiveness.
| Supplement | Potential Benefit | Evidence |
|---|---|---|
| Chromium | Minor weight loss | Limited evidence |
| Green tea extract | Weight loss | Associated with liver damage |
| Raspberry ketones | Weight loss | Insufficient studies |
| Capsaicin | Reduced energy intake | No significant impact on weight |
| Caffeine | Modest effect on body weight | Short-term effects only |
| Bitter orange | Increases metabolic rate | Inconclusive results |
The effectiveness of dietary supplements is often questioned due to the lack of extensive and high-quality research. The FDA bans substances like ephedra due to severe side effects, highlighting the need for safety.
It's important to talk to a healthcare professional before adding supplements to your weight-loss plan. While some supplements might offer benefits, their impact is usually small. They work best when combined with a balanced diet and regular exercise.
How Regular Exercise Improves Cardiovascular Health
Regular exercise is a powerful tool for improving cardiovascular health. It boosts blood circulation, strengthens the heart, and lowers blood pressure. Let's explore how exercise prevents heart disease and the best exercises for heart health.
Exercise and Heart Disease Prevention
Exercise is a great way to prevent heart disease. It can lower blood pressure, reduce diabetes risk, and keep a healthy weight. People who exercise regularly are less likely to have heart attacks or other serious heart problems.
The American Heart Association recommends a mix of aerobic and resistance training for heart health. Adults should do at least 30 minutes of aerobic exercise, like walking or cycling, five days a week. Adding moderate weightlifting twice a week can also strengthen muscles and improve heart health.
Optimal Exercises for Heart Health
For heart health, certain exercises are more effective. Aerobic activities like jogging, cycling, and swimming improve blood flow and raise good cholesterol. These activities also help lose fat around the waist, which is good for the heart.
Start with easy activities and gradually increase the intensity. For example, beginners can walk at 3 mph to reach a heart rate of 120 bpm. As fitness improves, increase the speed or incline to keep the heart rate up.
Resistance training is also key. Try curling a 15-pound dumbbell 12-15 times. As you get stronger, add 3-5 pounds to the weight. This helps improve overall heart health by better managing blood sugar and improving blood vessel function.
| Exercise Type | Frequency | Benefits |
|---|---|---|
| Aerobic (e.g., jogging, cycling) | 5 days/week for 30 minutes | Improves blood circulation, lowers blood pressure, enhances cardiovascular fitness |
| Resistance Training (e.g., weightlifting) | 2 days/week | Strengthens major muscle groups, aids in blood glucose homeostasis, improves metabolic health |
Conclusion
In this guide, we've looked at many ways to lose weight, focusing on exercise and diet. The Singapore Physical Activity Guidelines say you should do strength training twice a week to stay healthy. Also, doing moderate exercises can make you breathe harder, but still talk easily, which helps your fitness.
But, a study in the Journal of Strength and Conditioning Research found that 70% of overweight women gained fat during a fitness program. This shows that just exercising isn't enough for losing weight. Eating right is just as key, with My Healthy Plate suggesting a balanced diet.
Creating a daily calorie deficit of 500 to 1,000 calories can lead to losing 0.5 to 1 kg each week. Both what you eat and how much you exercise help with this. For example, running at a moderate pace burns about 300 calories per hour, while intense interval runs burn around 500 calories.
In conclusion, the best way to manage weight is by combining exercise and diet, tailored to your needs. Being active is important, but so is eating well. With more chances for good nutrition from eating four times a day than from exercising five times a week, diet is crucial. This shows that keeping healthy involves both exercise and diet. A balanced routine is essential for lasting weight loss success.
