The Complete Weight Loss Guide

Everything you need to know about losing weight effectively and keeping it off forever. Science-backed strategies that actually work.

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:

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.

Carbohydrates: Fuel for Performance

After setting protein and fat, the remaining calories come from carbohydrates.

Macronutrient Calories per Gram Recommended %
Protein 4 calories 30-40%
Fats 9 calories 25-35%
Carbohydrates 4 calories 30-45%

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:

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:

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:

When and How to Adjust

If weight loss stalls for 2+ weeks despite compliance:

  1. Reduce calories by 100-200 (reduce carbs/fats, keep protein high)
  2. Increase activity (add 1-2 cardio sessions or increase daily steps)
  3. 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

Social Situations and Restaurants

Handling Plateaus

Weight loss plateaus are normal and expected. Your body adapts to lower calories by:

Solutions: Increase steps, add cardio, reduce calories slightly, or take a diet break to reset.
