Step 1: Understanding Calories and Energy Balance
Weight loss fundamentally comes down to energy balance. To lose weight, you must consume fewer calories than your body burns. This is called a caloric deficit.
How Many Calories Do You Need?
Your Total Daily Energy Expenditure (TDEE) is the total number of calories you burn in a day. It consists of:
- Basal Metabolic Rate (BMR): Calories burned at rest (60-75% of TDEE)
- Thermic Effect of Food (TEF): Calories burned digesting food (10% of TDEE)
- Exercise Activity Thermogenesis (EAT): Calories burned during exercise (5-15% of TDEE)
- Non-Exercise Activity Thermogenesis (NEAT): Calories from daily movement (15-30% of TDEE)
Calculate Your Calorie Needs
Step 1: Calculate your BMR using the Mifflin-St Jeor equation:
Men: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) + 5
Women: BMR = (10 × weight in kg) + (6.25 × height in cm) - (5 × age) - 161
Step 2: Multiply by activity factor:
- Sedentary (little exercise): BMR × 1.2
- Lightly active (1-3 days/week): BMR × 1.375
- Moderately active (3-5 days/week): BMR × 1.55
- Very active (6-7 days/week): BMR × 1.725
- Extremely active (athlete): BMR × 1.9
Step 3: Create a deficit of 300-750 calories for weight loss
Recommended Rate of Weight Loss
Aim to lose 0.5-1% of body weight per week. This typically means:
- 0.5-1 lb per week for women
- 1-2 lbs per week for men
- Slower rates preserve more muscle mass
- Faster rates risk muscle loss and metabolic adaptation
Step 2: Macronutrient Distribution
Once you know your calorie target, you need to distribute those calories across the three macronutrients: protein, carbohydrates, and fats.
Protein: The Foundation
Protein is crucial for preserving muscle mass during weight loss, increasing satiety, and supporting recovery.
Protein Targets
- Minimum: 0.7g per lb of body weight (1.6g per kg)
- Optimal: 0.8-1g per lb of body weight (1.8-2.2g per kg)
- Higher body fat? Base on lean body mass instead of total weight
Fats: Essential for Hormones
Dietary fat is necessary for hormone production, vitamin absorption, and overall health.
- Minimum: 0.3g per lb of body weight (0.7g per kg)
- Optimal: 0.4-0.5g per lb of body weight (0.9-1.1g per kg)
- Never go below 20% of total calories from fat
Carbohydrates: Fuel for Performance
After setting protein and fat, the remaining calories come from carbohydrates.
- Carbs fuel intense exercise and support recovery
- No minimum requirement, but performance benefits from adequate intake
- Adjust based on activity level and personal preference

Step 3: Meal Planning and Food Choices
Focus on Whole Foods
Prioritize nutrient-dense, minimally processed foods that keep you full and provide essential nutrients.
Top Protein Sources
- Chicken breast, turkey, lean beef
- Fish: salmon, tuna, cod, tilapia
- Eggs and egg whites
- Greek yogurt, cottage cheese
- Protein powder (whey, casein, plant-based)
- Legumes: beans, lentils, chickpeas
Healthy Carbohydrate Sources
- Oats, quinoa, brown rice, sweet potatoes
- Whole grain bread and pasta
- Fruits: berries, apples, bananas
- Vegetables: all types, unlimited quantities
Healthy Fat Sources
- Avocado, nuts, seeds
- Olive oil, coconut oil
- Fatty fish: salmon, mackerel
- Nut butters (watch portions)
PRO TIP: Use the "80/20 rule" - make 80% of your calories from whole, nutrient-dense foods, and allow 20% for flexibility and foods you enjoy. This makes your diet sustainable long-term.
Step 4: Training for Fat Loss
Resistance Training is Essential
Lifting weights is the most important type of exercise for fat loss because it:
- Preserves and builds muscle mass
- Increases metabolic rate
- Improves body composition
- Creates the "toned" look most people want
Optimal Training Split for Fat Loss
Beginner (3 days/week):
- Full body workouts (Monday, Wednesday, Friday)
- Focus on compound movements
- 3-4 sets of 8-12 reps per exercise
Intermediate (4-5 days/week):
- Upper/Lower split or Push/Pull/Legs
- Mix of compound and isolation exercises
- 3-5 sets of 6-15 reps depending on exercise
Cardio: The Supporting Actor
Cardio helps create a calorie deficit but isn't necessary for fat loss. Use it strategically:
- LISS (Low Intensity Steady State): Walking, easy cycling - great for recovery and additional calorie burn
- HIIT (High Intensity Interval Training): Sprint intervals - time-efficient but taxing on recovery
- Start with 2-3 cardio sessions per week
- Add more only if weight loss stalls
PRO TIP: Focus on increasing daily movement (NEAT) before adding more cardio. Park farther away, take the stairs, go for walks. This burns calories without impacting recovery.
Step 5: Tracking Progress and Making Adjustments
How to Track Effectively
Don't rely solely on the scale. Use multiple metrics:
- Body Weight: Weigh daily, average weekly to account for fluctuations
- Measurements: Waist, hips, chest, arms, thighs weekly
- Progress Photos: Same lighting, angle, clothing every 2 weeks
- How Clothes Fit: Subjective but valuable feedback
- Performance: Are you maintaining strength in the gym?
When and How to Adjust
If weight loss stalls for 2+ weeks despite compliance:
- Reduce calories by 100-200 (reduce carbs/fats, keep protein high)
- Increase activity (add 1-2 cardio sessions or increase daily steps)
- Take a diet break (eat at maintenance for 1-2 weeks if dieting 12+ weeks)
IMPORTANT: Weight fluctuates daily due to water retention, digestion, stress, and hormones. Never make decisions based on one day. Look at the 7-day average trend.
Step 6: Overcoming Common Challenges
Dealing with Hunger
- Prioritize protein at every meal (most satiating)
- Eat high-volume, low-calorie foods (vegetables)
- Drink plenty of water (often mistaken for hunger)
- Get adequate sleep (poor sleep increases hunger hormones)
- Consider meal timing that works for you (some do better with breakfast, others skip it)
Social Situations and Restaurants
- Check menu in advance and plan your meal
- Opt for grilled proteins and vegetables
- Ask for dressings and sauces on the side
- Don't arrive starving (have a protein snack before)
- Remember: one meal won't derail progress
Handling Plateaus
Weight loss plateaus are normal and expected. Your body adapts to lower calories by:
- Reducing NEAT (unconsciously moving less)
- Becoming more efficient at exercise
- Lowering metabolic rate slightly
Solutions: Increase steps, add cardio, reduce calories slightly, or take a diet break to reset.
