Why protein matters more when you eat less

When you cut calories, your body looks for energy wherever it can. Some of that can come from muscle. Losing muscle is not what most people want. It can leave you weaker and lower the calories you burn.

Eating more protein, along with strength training, helps protect that muscle. That is why this version asks for more protein than you would need to simply maintain your weight.

What this version sets up for you

This page starts with the goal set to "Lose fat." That does two things:

  • Protein: your range uses 1.6 to 2.2 grams per kilogram of body weight.
  • Calories: your target is 20% below your maintenance calories, but never under 1,200 for women or 1,500 for men.

Here is an example. A 145 lb (66 kg) woman who is lightly active gets 105 to 145 grams of protein a day. Her calories come out to about 1,460 a day, down from about 1,830 to maintain. At the middle of her range, protein makes up about a third of her calories.

Tips while you lose weight

  • Keep your pace steady. The CDC notes that people who lose about 1 to 2 lb (0.5 to 0.9 kg) a week are more likely to keep it off. Our calorie deficit calculator can help you plan it.
  • Put protein on your plate first. Fill in vegetables and starches around it.
  • Track your progress with more than the scale. Our weight loss percentage calculator shows how far you have come.

Frequently asked questions

How much protein should I eat a day to lose weight?

This calculator uses 1.6 to 2.2 grams per kilogram of body weight a day for fat loss (about 0.73 to 1 g per pound). For a 145 lb (66 kg) person, that is about 105 to 145 grams a day. If your BMI is over 30, we use a lower reference weight so the target stays realistic.

Should I base protein on my current weight or my goal weight?

This calculator uses your current weight, unless your BMI is over 30. Then it uses the weight you would be at a BMI of 30 for your height, because extra body fat does not need extra protein. For someone who is 5 ft 5 in (165 cm), that is about 180 lb (82 kg).

Why is the protein range for weight loss so high?

When you eat less than you burn, your body can break down muscle along with fat. A sports nutrition position stand notes that higher protein intakes help people keep lean mass during a calorie deficit. Strength training helps too.

How much protein per meal should I eat to lose weight?

Split your daily target across your meals. For a target of 105 to 145 grams, that is about 35 to 48 grams at each of three meals. If that feels like a lot, pick the '3 meals + snack' option to spread it out.
