What Is the Best Way to Lose Weight? (The Complete, Honest Guide)
The science-backed, no-gimmick guide for Singaporeans who want to lose fat for good — including how to eat at hawker centres and still see results.
Every week, there's a new diet trend promising you'll drop 10kg in 30 days. Keto. Intermittent fasting. Juice cleanses. Low carb. No sugar. Six meals a day. Zero meals a day. It's overwhelming — and most of it is noise designed to sell you something. Here's the truth the fitness industry doesn't want you to overthink: the best way to lose weight is to consistently burn more calories than you eat, fuelled by whole foods, supported by exercise, and sustained over time. That's the whole formula. Everything else is detail — and this guide goes deep on every part so you can actually use it.
The Non-Negotiable Foundation: Calorie Balance
Your body is an energy system. It runs on calories. When you eat more than you burn, your body stores the excess as body fat. When you eat less than you burn, your body pulls from those fat stores for energy — and you lose weight.
This is called a calorie deficit, and it is the single most important concept in fat loss. No diet on earth bypasses this rule. Keto works because cutting carbs tends to reduce total calorie intake. Intermittent fasting works because compressing your eating window often leads to eating less. They're not magic — they're just different roads to the same destination: fewer calories in than out.
How Big Should Your Deficit Be?
A deficit of 300–500 calories per day is the sweet spot for most people:
- 300 cal/day deficit → approximately 0.3kg of fat lost per week (slow and very sustainable)
- 500 cal/day deficit → approximately 0.5kg of fat lost per week (the most commonly recommended rate)
- 750–1,000 cal/day deficit → approximately 0.75–1kg per week (aggressive, harder to sustain, more muscle loss risk)
For most beginners, aim for a 300 to 500 calorie deficit. It's meaningful enough to see progress on the scale every week, but moderate enough that you won't feel depleted, lose muscle, or quit after two weeks.
Step 1: Calculate Your Personal Calorie Target
To create a deficit, you first need to know how many calories your body burns per day — your TDEE (Total Daily Energy Expenditure).
Your TDEE is made up of:
- BMR (Basal Metabolic Rate) — calories burned just keeping you alive. Accounts for 60–70% of your total calorie burn.
- NEAT (Non-Exercise Activity Thermogenesis) — calories burned through non-gym movement: walking, fidgeting, household chores.
- Exercise — calories burned during workouts.
- TEF (Thermic Effect of Food) — calories burned digesting food (~10% of your total intake).
Use a free TDEE calculator online. Input your age, height, weight, and activity level. Subtract 300–500 from the result — that's your daily calorie target.
Step 2: Track What You Eat
You can't manage what you don't measure. Research consistently shows people who track their food lose significantly more weight than those who don't. Use MyFitnessPal or Cronometer for at least 4–6 weeks.
Tips for accurate tracking:
- Weigh food raw, not cooked
- Log oils, sauces, and condiments — they add up fast
- Scan barcodes rather than manually searching
- Log before you eat, not after — it changes your decisions
Step 3: Build Your Plate Around These Principles
Protein First — Every Single Meal
Protein is the most important macronutrient for weight loss:
- Most satiating macronutrient — suppresses hunger hormones better than carbs or fat
- Preserves muscle mass during a calorie deficit
- High thermic effect — your body burns 25–30% of protein's calories just digesting it
- Supports lean body composition as you lose fat
Target: 1.6–2.2g of protein per kg of bodyweight daily. Best sources: chicken breast, eggs, Greek yoghurt, tuna, lean beef, cottage cheese, tofu.
Fill Half Your Plate With Vegetables
High fibre, extremely low calorie, very filling. Broccoli: 34 cal/100g. Spinach: 23 cal/100g. Cucumber: 15 cal/100g. Fill half your plate before adding anything else.
Choose Smart Carbs
Whole-food carbs (oats, sweet potato, brown rice, legumes, fruit) digest slowly and keep hunger at bay. Refined carbs (white bread, pastries, sugary snacks) spike blood sugar and leave you hungry within an hour.
Manage Fat Portions
Healthy fats are essential — but at 9 cal/gram they're calorie-dense. Include avocado, olive oil, nuts, and salmon daily, but measure portions rather than estimating.

Liquid Calories
Drinks don't trigger satiety like food does. Bubble tea: 300–600 cal. Latte with syrup: 250–400 cal. Orange juice: 110 cal with no fibre. Switch to water, black coffee, and plain tea — this alone can cut 300–600 calories daily.
Weekend Eating
Two days of 1,000 calories over maintenance cancel five days of 500-calorie deficits. Weekends count. Allow one free meal — not one free day.
Step 5: Use Exercise to Accelerate Results
Strength Training (2–3x per week)
Builds muscle that burns calories 24/7. Beginners often experience simultaneous fat loss and muscle gain — body recomposition — when starting strength training.
Cardio (2–3x per week)
Burns extra calories and improves heart health. Start with LISS (30–45 min incline walks, cycling, swimming). Add HIIT sessions once fitness improves.
NEAT — Daily Movement
NEAT can vary by 2,000 calories per day between individuals. Aim for 8,000–10,000 steps daily. Park further away. Take the stairs. Walk while on calls.
Step 6: Optimise Recovery
Sleep 7–9 hours per night. Sleep deprivation increases hunger hormones by 24%, reduces fullness hormones, elevates cortisol, and causes people to consume 300–500 more calories per day. It's not optional — it's part of the programme.
Manage stress. Chronic cortisol elevation promotes abdominal fat storage and triggers cravings for high-calorie foods.
What Works vs. What Doesn't
✅ What Actually Works
- Moderate 300–500 kcal daily deficit
- High protein at every meal (1.6–2.2g/kg)
- Half your plate filled with vegetables
- Strength training 2–3x per week
- Cardio and 8,000–10,000 daily steps
- Tracking your food for 4–6 weeks
- 7–9 hours of sleep per night
- One free meal per week — not a free day
- Weekly average weigh-ins
- Consistency over months, not days
❌ What Doesn't Work
- Detox teas — temporary water loss, nothing else
- Fat burner supplements — caffeine at a massive markup
- Extreme diets under 1,000 calories — muscle loss and guaranteed rebound
- Daily weigh-ins and panicking over fluctuations
- Cardio only, no weights — a smaller version of the same shape
- Cutting out entire food groups forever
- "Starting again on Monday" every single week
- Guessing portions instead of measuring
- Out-exercising a bad diet
- Going it alone with zero accountability
Sustainable Fat Loss vs. Crash Dieting: A Real Comparison
| Factor | Sustainable Approach | Crash Diet |
|---|---|---|
| Rate of Loss | ✔ 0.5–1kg/week, mostly fat | ✘ Fast at first — mostly water and muscle |
| Muscle Mass | ✔ Preserved with protein + training | ✘ Significant muscle loss |
| Metabolism | ✔ Maintained or improved | ✘ Slows down to adapt |
| Energy Levels | ✔ Stable throughout the day | ✘ Crashes, brain fog, irritability |
| Hunger | ✔ Managed with protein and fibre | ✘ Constant, willpower-draining |
| Hawker Meals & Social Life | ✔ Built into the plan | ✘ "Can't eat anything" — isolation |
| Rebound Risk | ✔ Low — habits stick | ✘ Near-guaranteed regain, often more |
| 12-Month Outcome | ✔ Lighter, stronger, leaner | ✘ Back to square one — or worse |
