Protein for Weight Loss: How Much You Need & Best Sources

Why Protein Matters More Than Any Other Macro

If you could change only one thing about your diet for weight loss, it should be eating more protein. Here's why protein is uniquely powerful:

1. Protein Keeps You Full

Protein is the most satiating macronutrient. Studies show that increasing protein intake from 15% to 30% of calories causes people to eat 441 fewer calories per day — without trying. That's almost a pound of weight loss per week from just feeling less hungry.

2. Protein Preserves Muscle

When you're in a calorie deficit, your body burns both fat and muscle for energy. Adequate protein intake signals your body to preserve muscle and burn fat instead. This is critical because muscle tissue burns more calories at rest, keeping your metabolism healthy.

3. Protein Burns More Calories to Digest

The thermic effect of protein is 20-30%, meaning your body burns 20-30% of protein calories just digesting it. Compare that to 5-10% for carbs and 0-3% for fat. Eating 100 calories of chicken breast costs your body 25 calories to process. Eating 100 calories of butter costs just 2.

How Much Protein Do You Need?

The standard recommendation for weight loss is:

• 0.7-1.0g per pound of body weight (or 1.6-2.2g per kg)

For example:

• 150 lb person: 105-150g protein per day
• 180 lb person: 126-180g protein per day
• 200 lb person: 140-200g protein per day

If you're significantly overweight, use your goal weight instead of your current weight for this calculation.

Tracking Your Protein

The biggest challenge with protein is consistency. It's easy to eat enough protein at dinner but fall short at breakfast and lunch.
