Sustainable Weight Loss: Evidence-Based Strategies

Losing weight and keeping it off doesn’t require extreme diets or quick fixes. Instead, it’s about making small, consistent changes to your daily habits. Here’s what works:

• Balanced Diet: Focus on nutrient-rich foods like vegetables, fruits, lean proteins, whole grains, and healthy fats. Avoid extreme diets and practice portion control, especially when dining at hawker centres or during festive meals.
• Regular Exercise: Aim for activities you enjoy, whether it’s walking, swimming, or using fitness corners. Everyday movements like taking the stairs or walking more also help.
• Behavioural Changes: Track your meals, set specific goals, and plan ahead to avoid impulsive eating. Manage stress and get enough sleep to support your efforts.
• Medical Support: For those struggling with weight-related health issues, GLP-1 medications like semaglutide or telehealth services like Trimly can offer additional help.

Even losing just 5–10% of your weight can improve your health, reducing risks of diabetes, heart disease, and more. Success comes from consistency, not perfection. With a realistic plan and proper support, long-term results are within reach.

The Sustainable Path to Healthy Weight Loss and More Energy

The Science Behind Weight Loss

Achieving lasting weight loss involves a combination of good nutrition, regular exercise, and gradual behaviour changes. Let’s delve into how energy balance and metabolism come into play in this process.

How Energy Balance and Metabolism Work

At its core, weight loss boils down to energy balance - burning more calories than you consume. This concept, combined with factors like metabolism, hormones, and genetics, lays the groundwork for sustainable weight loss.

Experts suggest creating a moderate calorie deficit of 500–750 calories per day. This approach can lead to a healthy weight loss rate of about 0.5–1 kg per week.

Nutrition Strategies for Singapore

Losing weight doesn’t mean going hungry. It’s about making smarter food choices that leave you feeling satisfied. Nutrient-dense options like vegetables, fruits, lean proteins, whole grains, and healthy fats are your best allies. Steer clear of extreme diets; instead, aim for balance and variety.

Protein and fibre are particularly helpful as they keep you full and may even slightly boost your metabolism. When dining at hawker centres, opt for dishes loaded with vegetables and lean proteins. Swap white rice for brown rice and keep an eye on portion sizes. Look out for the Healthier Choice Symbol (HCS) on packaged foods to guide your decisions.

Building sustainable eating habits is about small, manageable changes. Rather than cutting out entire food groups, focus on portion control and a balanced plate. This approach is especially helpful given the hearty servings often found at local eateries.

Exercise and Physical Activity

Exercise isn’t just for shedding kilos - it’s crucial for maintaining weight loss in the long run. Singapore’s urban landscape offers a variety of ways to stay active, from the park connector networks and cycling paths to fitness corners in HDB estates.

To minimise the risk of injury, choose activities that suit your fitness level and lifestyle. Whether it’s a morning stroll at East Coast Park, a swim at a community pool, or a group fitness class, finding something you enjoy will keep you motivated. Given Singapore’s hot and rainy weather, indoor workouts can also be a practical option.

Beyond structured workouts, everyday movements, known as Non-Exercise Activity Thermogenesis (NEAT), can make a big difference. Small actions like taking the stairs, walking to the MRT station, or standing while working can significantly increase your daily calorie burn. Incorporating these habits into your routine is an effective way to support long-term weight loss.

Behaviour and Mental Health in Weight Loss

Achieving sustainable weight loss isn't just about diet and exercise - it also requires attention to mental and behavioural factors. Obesity stems from a complex interplay of genetic, environmental, behavioural, psychological, and socioeconomic influences. Understanding these factors can help transform short-term efforts into long-term success.

Behaviour Change Techniques That Work

Creating lasting habits requires targeted strategies. One effective method is self-monitoring, where you track your food intake, physical activity, and weight. This helps you spot patterns and triggers that might otherwise go unnoticed.

Setting goals is another powerful tool. The most effective goals follow the SMART framework: specific, measurable, achievable, relevant, and time-bound. Instead of vague objectives like "lose weight", focus on actionable steps such as "walk 30 minutes daily" or "prepare lunch at home four times a week". These specific goals make it easier to measure progress and stay motivated.

Meal planning is especially helpful in avoiding impulsive decisions, which can be a challenge in Singapore's vibrant hawker centres. Planning your meals ensures you have healthier options on hand, supports a steady metabolism, and helps you resist spur-of-the-moment cravings. Practising mindful eating can also help you differentiate between physical hunger and emotional cravings. And if you slip up, having a plan to recover from setbacks can keep you moving forward without losing confidence.

Beyond behavioural strategies, addressing physiological factors like sleep and stress is equally important.

Managing Sleep and Stress

Lack of sleep and chronic stress can derail weight loss efforts by disrupting hunger hormones and increasing cortisol levels, which encourages fat storage.

In Singapore's high-pressure work culture, managing stress is essential. Set boundaries for your work hours, practise mindfulness during your commute, or take short walks throughout the day. And don’t underestimate the importance of sleep - aiming for 7–8 hours of quality rest each night is a cornerstone of any weight loss plan, not just a luxury.

Social and Cultural Factors in Singapore

Weight loss efforts in Singapore are also shaped by social and cultural dynamics. Singapore's food-centric culture, where social gatherings often revolve around meals, can make it challenging to stick to healthier choices. Turning down food might sometimes feel impolite, and societal expectations around body image can create additional pressure. Weight stigma, too, can impact self-esteem and motivation.

However, social support can make all the difference. Sharing your goals with friends and family can foster accountability and understanding. Joining group-based programmes or connecting with others who share similar goals can provide encouragement and solidarity. When healthcare providers treat obesity as a chronic condition rather than a personal failing, it helps remove stigma and promotes compassionate care. Having a strong support network - whether it's friends, family, or a community group - can help you navigate challenges and stay committed to your journey.

Medical Support and Telehealth for Weight Loss

When diet and exercise alone aren't enough, medical interventions can play a crucial role in supporting sustainable weight loss as part of a well-rounded, science-backed approach.

When to Consider Medical Weight Management

Medical weight management becomes important when lifestyle changes don't deliver lasting results or when weight-related health conditions arise. For Asian populations, including Singaporeans, obesity is defined as a BMI of ≥27.5 kg/m², while being overweight falls between 23–27.4 kg/m². Additionally, a waist circumference above 90 cm for men or 80 cm for women signals higher health risks.

If personal efforts to manage weight aren't working, seeking professional help is key. For instance, a physiotherapist (F12) noted that many patients deal with weight-related musculoskeletal issues that, while significant, might not require specialised hospital care. Regular medical check-ups are essential to track factors like liver and kidney function, cardiovascular health, blood sugar levels, and overall nutrition.

How GLP-1 Medications Work

GLP-1 receptor agonists are modern medications designed for long-term weight loss and work best when paired with lifestyle changes. These drugs mimic hormones that control appetite and blood sugar, helping reduce cravings and keeping you feeling full for longer.

Different GLP-1 medications offer varying results: liraglutide can lead to 5–8% weight loss, semaglutide 10–15%, and tirzepatide up to 15–20%. They are often recommended when lifestyle adjustments alone aren't enough or when weight loss plateaus. The noticeable progress from these medications can also provide the motivation needed to maintain healthier habits over time.

Trimly's Telehealth Weight Loss Services

Creating a Long-Term Weight Loss Plan

Sustainable weight loss isn't about quick fixes - it’s about creating a personalised approach that fits into your lifestyle and continues to work even after you’ve hit your initial goals. The focus should be on developing strategies that are realistic and easy to maintain over time.

Setting Achievable Goals

To start, aim for a daily calorie deficit of 500–750, which can help you lose about 0.5–1 kg per week. Break your overall weight loss target into smaller, more manageable milestones. Beyond just tracking your weight, think about setting goals that reflect broader improvements in your well-being, like increased energy levels or better sleep. Keep in mind that forming new habits takes time, so patience is key.

These smaller steps can help you build a foundation for healthy routines that last.

Building Daily Routines

With clear goals in mind, create daily habits that support them. In Singapore, where food is a big part of the culture, planning ahead can make healthier choices easier. For example, prepare simple breakfasts or pack balanced lunches during the workweek to avoid last-minute decisions at food courts. When eating out, look for options like steamed or grilled dishes and add extra vegetables to your meal. During festive occasions like Chinese New Year or Deepavali, enjoy traditional foods in smaller portions and balance heavier meals with lighter ones throughout the day. Late-night suppers? Opt for soup-based dishes or share meals to keep portions in check.

Maintaining Your Weight Loss

To sustain your progress, consistent self-monitoring is essential. Regularly checking in on your weight and habits can help you catch small gains before they become bigger setbacks. Staying active is also a critical part of maintaining results over the long term. Instead of returning to restrictive diets, focus on adopting eating patterns that you can stick to for life. Periodic check-ins with healthcare providers, whether in person or through telehealth, can provide valuable guidance. Additionally, having a support system - be it workout buddies, family, or professional advice - can make all the difference in staying on track.

Conclusion: Your Path to Lasting Weight Loss

Achieving sustainable weight loss is more than just shedding kilos - it's about embracing a healthier lifestyle through practical strategies, professional guidance, and personal dedication. Research shows that even a modest weight reduction of 5–10% can bring about significant health improvements, such as better heart health, improved type 2 diabetes management, and a lower risk of fatty liver disease.

The core principles of successful weight loss remain straightforward: eating a balanced diet, staying physically active, and addressing behaviours that contribute to weight gain. In Singapore, where food culture thrives, practising portion control and staying active are particularly relevant. It's also important to recognise that managing obesity often requires a long-term, well-rounded approach.

Professional support can make a big difference. For instance, GLP-1 receptor agonists offer an effective boost when progress slows. Telehealth services, like those provided by Trimly, bring doctor-led programmes, tailored treatment plans, and continuous monitoring right to your fingertips. Coupled with digital health tools, these resources make it easier to achieve and maintain weight loss over the long term.

Consistency is the secret to success - not perfection. Regularly tracking your progress and scheduling check-ups can help you stay focused. Building a network of support, whether through loved ones or professionals, provides the motivation and accountability needed to overcome challenges.

Your weight loss journey is personal, and having the right support can make all the difference. With evidence-based strategies and accessible telehealth services, long-term, sustainable weight loss is well within your reach.

FAQs

What are the essential steps for achieving sustainable weight loss?

Sustainable weight loss isn’t about quick fixes or extreme diets - it’s about finding a balance that works for you and sticking with it. Start by focusing on healthy eating habits: include nutrient-rich foods in your meals, practise portion control, and enjoy a variety of fruits, vegetables, whole grains, and lean proteins. Pair that with regular physical activity, aiming for 150–300 minutes of moderate exercise each week. Activities like brisk walking or cycling are great options, and adding some resistance training can help build muscle and keep your metabolism active.

Equally important are lifestyle and behavioural adjustments. Set realistic goals that you can achieve step by step, keep track of your progress, and stay mindful of your eating patterns. For example, monitoring your weight and daily habits can help you spot areas that need tweaking. The key is to focus on gradual changes that you can maintain over time, creating a healthier lifestyle that supports your long-term well-being.

How do GLP-1 medications support sustainable weight loss?

GLP-1 medications support weight loss by curbing appetite, increasing the sense of fullness, and slowing down how quickly food moves through the stomach. These combined effects often result in consuming fewer calories, leading to steady and lasting weight reduction.

These medications mimic a natural hormone in the body responsible for regulating hunger and digestion. By doing so, they help make it more manageable to control eating habits and stick to a healthier lifestyle over the long term.

How can I maintain a healthy weight in Singapore’s food-loving culture?

Maintaining a healthy weight in Singapore’s food-focused culture is possible with a mix of mindful eating and active habits. Start by practising portion control and selecting healthier options like wholegrain foods, lean proteins, and dishes prepared with less oil or sugar. When dining out, you can share rich dishes or opt for smaller portions to enjoy your favourite local meals without overdoing it.

Make regular exercise a part of your lifestyle. Aim for 150–300 minutes of moderate aerobic activity per week - think brisk walking or cycling. Add resistance training to strengthen muscles and support weight management. Singapore offers plenty of opportunities to stay active, from scenic parks and fitness corners to community exercise programmes.

You can also embrace local traditions by tweaking recipes to include healthier ingredients. Get your family or friends involved in active outings, blending quality time with fitness. This way, you can relish Singapore’s rich food culture while keeping your health goals in check.
