Keep reading to learn more about protein’s role in weight loss and how to eat a high protein diet.
Protein is one of the three macronutrients, along with carbs and fat. It plays a key role in the formation, maintenance, and structure of your organs and tissues.
Protein has many important bodily functions, such as:
Protein is made up of a chain that contains 20 smaller units called amino acids. Of these, nine are considered essential amino acids. They must be consumed in food because your body can’t make them.
Protein’s effects on weight loss
Increasing your protein intake may help promote weight loss in many different ways.
Appetite and fullness
Protein
These effects of a high protein intake could lead to a natural reduction in food intake.
Metabolic rate
A
Protein may also increase how much energy your body uses to absorb, metabolize, and store food. This is called the thermic effect of food (TEF). The TEF for protein is 20–30%, meaning that 20–30% of the calories found in protein are used simply to digest it. Meanwhile, the TEF for carbs and fat is 5–10% and 0–3%, respectively.
Body composition
Protein’s ability to suppress appetite, promote fullness, and increase your metabolism can help you lose weight.
A
Typically, when you reduce your calorie intake, your metabolism slows down. This is partly due to muscle loss. However, a higher protein intake can help protect against muscle loss and keep your metabolic rate up.

How much protein should you eat every day?
The amount of protein you need every day depends on several factors, such as your age and sex. The exact amount is also somewhat controversial.

However, the authors of a
Research suggests that eating more protein than the RDA may promote weight loss and overall health. For example:
- A
2017 study found that participants who ate a high protein diet of 1.34 g/kg/bw (0.6 g/lbs/bw) for more than 75% of the 6-month duration experienced significantly more weight loss than the group who followed the RDA requirements. - A
2016 review found that eating up to 2 g/kg/bw (0.9 g/lbs/bw) may help promote strength and prevent muscle degeneration. - A 2015 study found that females ages 65 years and older require 1.3 g/kg/bw (0.6 g/lbs/bw) of protein to help prevent age-related muscle loss.
- A 2015 review found that eating up to 1.6 g/kg/bw (0.7 g/lbs/bw) per day can help promote weight loss, reduce body fat, and maintain muscle mass.
Consuming protein beyond 2 g/kg/bw (0.9 g/lbs/bw) may not provide additional benefits. A
A high protein diet for weight loss and overall health should provide about
So, if you weigh 68 kg (150 lbs), this provides 82–136 g of protein daily.
