Rethinking Weight Loss

Rethinking Weight Loss in 2025: Holistic, Sustainable Strategies

In 2025, the way people think about losing weight is undergoing a significant shift. Before, many people tried strict diets or quick methods that didn’t last. Now, people understand that being healthy isn't just about eating less food or losing weight fast. Instead, it's about caring for your entire body and forming lasting good habits. More people want to improve their overall health, feel stronger, and have more energy daily.

Old methods usually only worked for a short time and often left people feeling disappointed. However, new approaches, based on science and objective evidence, demonstrate the importance of focusing on long-term health rather than short-term results. By helping your body become healthier and making small, steady changes, it becomes easier to maintain the weight loss. This new approach to weight loss is more nutritious, easier to follow, and ultimately more beneficial in the long run.

 

Why Fad Diets Fail: Metabolic Slowdown & Weight Regain

Many standard weight loss methods appear helpful initially, but most fail to work well over time. These ideas often promise quick results, but they rarely deliver lasting benefits. Here are some popular myths and the truth behind them:

 

Dieting Myth	The Reality
Eating a very low-calorie diet helps you lose weight quickly.	It slows down your body, making weight return easily.
Carbs are bad for losing weight.	Healthy carbs provide energy and support your body.
You must do lots of cardio to lose weight.	Building muscle with strength exercises burns fat more effectively.
Popular diets work forever.	95% of people regain their weight within five years.
Losing weight is often a sign of good health.	Having strong muscles and good health are more important.

Metabolic & Hormonal Health: Foundation of Sustainable Fat Loss

Losing weight isn't just about eating less food or exercising more. Instead, it's about helping your body stay healthy by caring for your metabolism, hormones, and muscles. When people adhere to very strict diets, their metabolism slows down, making it easier for them to regain weight later. Doctors call this "yo-yo dieting," and it's not healthy for your body.

Why It Matters

Maintaining a healthy metabolism allows your body to burn calories and fat more efficiently. Research shows that crash diets can slow down your metabolism and lead to weight regain. A study published in Obesity (2022) found that strict diets cause your body to use fewer calories, which means losing weight becomes harder over time.

How to Improve Metabolic Health

Here are some simple, science-backed ways to keep your metabolism strong and healthy:

 

• Eat Enough Protein: Protein helps your body keep muscle while losing fat. Muscle helps burn more calories, even when you're resting. A study found that eating more protein helps people feel full and lose weight more easily.
• Prioritise Strength Training: Doing exercises like lifting weights builds muscles. When you have more muscle, your body burns more calories throughout the day. A study has shown that individuals who regularly lift weights tend to lose more fat and have healthier bodies.
• Manage Stress & Sleep Well: When stressed, your body makes a hormone called cortisol, which can cause weight gain. Getting good sleep and managing stress can help keep cortisol levels low. A study has confirmed that relaxing activities, such as meditation, can help lower stress and promote overall health.
• Balance Blood Sugar: Eating whole foods like fruits, vegetables, and healthy grains keeps your blood sugar stable. Stable blood sugar means you'll feel less hungry and have more energy. Experts from Harvard Health suggest that balanced meals help prevent hunger spikes and make weight loss easier.
• Ditch Diet Culture & Restrictive Eating: Instead of following strict diets, it's better to build healthy habits that you can follow forever. According to a study published in Annual Reviews, adopting a balanced diet and maintaining healthy habits is most effective for achieving and sustaining long-term weight loss.

Strength Training vs Cardio: Best for Fat Loss & Metabolism

When people think about losing weight, they often choose cardio activities like running or cycling. However, new studies indicate that strength training—such as lifting weights or bodyweight exercises—works more effectively for achieving long-lasting fat loss.

 

Why It’s More Effective Than Cardio

Strength training helps your body burn calories both during and after your workout. When you lift weights, you build stronger muscles. More muscle means your body naturally burns more calories, even when resting or sleeping. A study found that strength training helps the body manage sugar more effectively and store less fat.

 

Another benefit of strength training is that it helps maintain muscle strength while you lose fat. People who only do cardio sometimes lose both muscle and fat. Losing muscle can slow down your metabolism, making it more challenging to maintain weight loss. Research shows that people who lift weights regularly lose more fat and maintain their muscle health.

 

Best Exercises for Fat Loss

These easy tips will help you use strength training to lose fat and stay healthy:

• Compound Movements: Compound movements, like squats, deadlifts, and push-ups, use many muscles simultaneously. The University of California research suggests that these exercises burn more calories and build muscle faster than exercises that focus on just one muscle.
• Progressive Overload: Slowly adding more weight or doing more repetitions over time helps your muscles grow stronger. A study found that steadily increasing the challenge helps your body burn more fat.
• 2-4 Sessions Per Week: Doing strength workouts two to four times weekly is enough to achieve great results. Experts say this frequency helps your body grow strong muscles without getting too tired.
• Walking & Light Movement: Gentle activities like walking every day also help you lose fat and stay healthy. Research published in The Lancet found that walking daily improves overall health and supports the benefits of strength training.

Gut Health & Weight Loss: Fibre, Ferments, Less Ultra-Processed

Many people think weight loss is solely about eating less and moving more, but scientists have discovered something else that matters significantly: your gut health. Inside your gut, there are millions of tiny helpful bacteria. These bacteria affect how hungry you feel, how your body uses food for energy, and how easily your body stores fat.

Why It Matters

Your gut bacteria control your appetite and help manage blood sugar levels. If these bacteria become unbalanced, you might crave more sugary or unhealthy foods, making it harder to lose weight. A study found that unhealthy gut bacteria can lead to intense cravings, causing people to eat more and gain weight. Another study has shown that problems in gut health can even cause your body to store fat more easily, leading to issues such as diabetes or other health problems.

How to Improve Gut Health for Weight Loss

Here are some easy ways to improve your gut health and help your body lose weight:

 

• Eat Fibre-rich Foods: Eating fruits, vegetables, and beans helps your good gut bacteria grow strong. These foods also help you feel full longer. Research shows that eating fibre-rich foods regularly can help your gut stay healthy and make weight loss easier.
• Include Probiotics & Fermented Foods: Probiotics are good bacteria in foods like yoghurt, kimchi, and kefir. Eating these foods regularly can help improve your digestion, reduce hunger, and promote a healthier gut. According to a study, probiotics can help people lose weight by strengthening their gut bacteria and making them more nutritious.
• Avoid Ultra-processed Foods & Artificial Sweeteners: Foods that are highly processed or contain artificial sweeteners can damage healthy gut bacteria. Eating these foods often leads to weight gain and unhealthy cravings. A study found that individuals who consume fewer processed foods have healthier gut bacteria and are more likely to lose weight.

Hormones & Fat Loss: Cortisol, Insulin, Thyroid, Oestrogen

Your body’s hormones are essential in how easily you can lose or gain weight, especially if you're a woman. Sometimes, hormones such as cortisol, insulin, thyroid hormones, and oestrogen become unbalanced, making it difficult to lose fat. When you address these hormonal issues first, losing weight becomes easier and more sustainable.

Why It’s Key to Weight Regulation

Hormones help control how hungry you feel, how your body uses energy, and where it stores fat. If these hormones aren't balanced, it can make losing weight harder. For example, cortisol, which is released when you're stressed, can cause extra fat storage around your stomach. Insulin helps control blood sugar, but your body stores more fat when insulin levels get too high. Thyroid hormones control how quickly your body burns calories, so low thyroid hormones can slow weight loss. Oestrogen, another vital hormone, can change where your body stores fat, especially as women age. Addressing these hormonal issues can help your body naturally shed fat more easily.

 

How to Optimise Hormonal Health

Here are some easy ways you can balance your hormones to help you lose weight:

 

• Prioritise Sleep & Stress Management: Getting enough sleep and managing stress helps control cortisol levels. Try incorporating relaxing activities, such as yoga, meditation, or taking short breaks throughout the day, to help reduce stress.
• Reduce Refined Sugar & Processed Foods: Eating less sugar and fewer processed snacks helps control insulin levels, making your body store less fat. Instead, opt for fruits, vegetables, and whole grains to help maintain balanced insulin levels.
• Eat Healthy Fats: Healthy fats from foods like avocados, nuts, olive oil, and fish help your body produce essential hormones. Eating these fats regularly helps balance your hormone levels and makes weight loss easier.
• Cycle Syncing Workouts: Changing your workouts based on your monthly cycle can help keep hormones balanced. For example, gentle exercises like yoga may be more suitable during your period, while more challenging workouts are beneficial when you feel stronger.

Beyond the Scale: Track Body Composition, Energy, Sleep 

Many people trying to lose weight pay too much attention to the number they see on the scale. However, this number doesn't tell you everything about your overall health. A better approach is to consider how your body changes—such as losing fat, gaining muscle, or becoming stronger and healthier overall.

Why Body Composition Matters More

The number on the scale only shows your total weight, but it doesn't say how much muscle or fat you have. You can lose fat and gain muscle simultaneously, but your overall weight may remain the same. Muscles weigh more than fat, but they take up less space. Your clothes fit better, even if the scale doesn't change. The World Health Organisation (WHO) explains that having more muscle and less fat is healthier and better for your body, even if your weight stays the same. People with more muscle typically have stronger bodies, more energy, and generally feel more energetic overall.

Non-Scale Ways to Measure Progress

Instead of using the scale, here are some easy ways to know if you're making progress:

 

• Clothes Fitting Better: If your clothes start fitting better or feel looser, you're losing fat and becoming healthier—even if your weight hasn't changed much.
• Increased Energy Levels & Endurance: Feeling more energetic or noticing that exercise becomes easier are signs that your body is improving. More energy means your body is getting stronger and healthier.
• Better Digestion, Mood, and Sleep Quality: If you notice sleeping better, feeling happier, or having fewer stomach problems, you're improving your health—even if the scale doesn't show it yet.
• Gains in Strength & Fitness Performance: Feeling stronger, lifting heavier weights, or running faster are clear signs you're becoming healthier. Being stronger helps your body burn calories better, making everyday activities easier.

 

You can refer to this helpful page from the World Health Organisation (WHO) to learn why body composition is more important than weight alone.

Lifelong Fat Loss: Protein, Lifting, NEAT, Sleep & Stress

Losing fat and staying healthy isn't about strict diets or quick fixes. It's about making simple changes you can follow every day. To maintain long-term health, focus on building a balanced lifestyle that benefits your entire body, rather than just losing weight quickly.

 

• Avoid the ‘All-or-Nothing’ Diet Mindset: Trying to be perfect with your diet usually doesn't work. Instead, aim for balance by choosing healthy foods most of the time while still enjoying treats occasionally. This way, you won't feel guilty or give up when you eat something you love.
• Focus on Building Muscle and Metabolism: If you eat too little food, your body slows down and burns fewer calories. It's better to build muscle by doing strength exercises regularly. Muscles help your body burn more calories, even when you're resting. Eating enough protein and staying active daily helps keep your body strong and energetic.
• Choose Real Food Instead of Processed Diet Products: Many diet products contain unhealthy ingredients and don't make you feel full. Eating natural foods like fruits, vegetables, meats, nuts, and whole grains gives your body the necessary vitamins. These foods also keep you full longer, so you don't get hungry as quickly.
• Do Strength Training and Stay Active Daily: Strength training helps build muscles and burn fat, making weight loss easier. Aim for at least two strength workouts each week. Additionally, simple daily activities like walking, playing outside, or riding a bike help keep your body active and healthy.
• Focus on Hormonal Balance, Gut Health, and Stress Reduction: Stress, hormones, and gut health affect how your body loses weight. Getting good sleep, managing stress with calming activities like yoga, and eating fibre-rich foods help your body stay balanced. These healthy habits make it easier to lose fat naturally and maintain a suitable weight for a long time.
