Illustration for How much protein should I eat to lose weight?

Target 1.8-2.2 grams of protein per kilogram of body weight daily to maximize fat loss and muscle preservation. Achieve this by consuming 25-30 grams of protein with each main meal.

Why Protein Helps You Drop Fat

When in a calorie deficit for fat loss, protein intake is crucial. Protein increases satiety more than carbohydrates or fats, reducing cravings and overall calorie intake. Crucially, sufficient protein preserves muscle mass during weight loss. Muscle burns more calories at rest than fat. Retaining muscle through adequate protein intake makes fat loss more effective and sustainable.

Calculating Your Daily Protein for Fat Loss

Calculate your daily protein target by multiplying your body weight in kilograms by 1.8-2.2. Convert pounds to kilograms by dividing by 2.2. Example: A 70 kg (154 lb) individual requires 126-154 grams of protein daily (70 kg * 1.8 = 126 g; 70 kg * 2.2 = 154 g). Distribute this intake across meals, aiming for 30-40 grams at three main meals, supplemented by protein-rich snacks.

Distribute Protein for Optimal Results

Protein distribution throughout the day is as crucial as total intake for fat loss. Aim for 25-30 grams of protein at each major meal. This consistent intake optimizes muscle protein synthesis and enhances satiety, surpassing the benefits of consuming protein in fewer, larger doses.

  1. Find your target.Multiply your body weight in kg by 1.8-2.2 for your daily protein goal.
  2. Distribute evenly.Aim for 25-30 g of protein at each breakfast, lunch, and dinner.
  3. Choose wisely.Prioritize lean meats, dairy, eggs, and plant-based proteins to hit your numbers.

Remember: Protein: Maximize fat loss, preserve muscle.
