Protein boost metabolism, suppress appetite and induce thermogenesis.

So, just adding protein-rich to your breakfast can be very helpful in weight loss very fast.

Eating protein-rich help you eat less for the rest of the day. How? We will discuss it in detail below.

Does protein help to lose weight fast?

Yes, protein helps to lose weight fast and eating protein-rich breakfast is the single and most powerful trick to lose weight fast. Protein and belly fat have an inverse relationship. More is the protein, lesser belly fat.

Mechanism of protein that helps to reduce belly fat and maintain a healthy weight.

1. The body burns more calories in the digestion of protein than carbs.

Our body also burns calories to digest the food that we eat also called the thermic effect of food (TEF). 

It is reported that the thermic effect of nutrients is 5-10 for carbs, 20-30% for protein, and 0-3% for fat. [2][3]. 

Although all studies haven’t the same figure, at least it is clear that protein has a higher thermic effect, which is two times higher than carbs and ten times higher than fat.

Our overall diet is generally 10% of daily total energy expenditure. This is because normally our diet is carbs centric. By eating higher you can increase this energy expenditure to 15-20 %.[2]

0-30% thermic effect of protein means if protein provides 100 calories, then 20-30calories were used to extract these calories and effective calories were 70-80.

This is also a good way to burn more calories by just eating.

2. It helps to suppress Appetite

Protein suppresses hunger and can help to create a calorie deficit. [4]

It helps you to eat fewer calories without even conscious about calorie intake. It also helps to decrease day-to-day calorie intake and you can create a significant calorie deficit at the end of the weeks.

A study shows that eating 30% of calories can help you to eat 441 fewer calories per day. [5]

3. It boosts metabolism significantly

Boosting metabolism is one of the key factors to lose belly fat and shed pounds of fat.

Some people have a naturally faster metabolism than others. Faster metabolism allows you to burn more calories naturally throughout the day. 

This makes the metabolism key factor in maintaining and losing weight. 

Protein found in every tissue of the body. It will prevent muscle loss, help you to increase muscle mass with weight training and exercise. [5

More is the muscle mass, the more energy will require to keep you alive also called basal metabolic rate (BMR). Because muscle tissue requires more energy. Increasing muscle mass will boost your BMR.[6][7][8]

Protein is harder to digest than carb. Our digestion system works harder to digest protein than carbs and fat. And this helps to accelerate the metabolic rate up to 20-35%.

More protein not only help with body composition and metabolism. But, also helps you hide under-fat, and look good.

4. Reduces cravings and prevent you from taking snacks

Craving can add tons of calories to your diet without even realizing it. Because of this, most of the people fail to achieve goals on their diets. This is the reason people gain weight, although they eat their meal consciously. 

But, protein may solve this problem for dieters and weight losers.

Protein helps to decrease the desire to eat by 15% and fast-food cravings by 15%. But, it helps to increase fullness by 25%. [9]

5. It can change weight regulating hormones

Weight gain or loss both is also regulated by the brain for example satiety is controlled by our brain part hypothalamus. [10][11]

Our body sends signals to the brain and our brain decides how much to eat, what to eat, and when to eat.

Eating high protein instead of fat or carbs increase satiety hormones and decrease hunger hormone.[12][13][14]

Eating high protein reduces hunger and creates a continuous calorie deficit without slowing down metabolism is the actual reason why a high protein diet results in automatic weight loss.

6. Protein can help you lose weight without calorie monitoring or doing anything new

Protein can help to lose weight and maintain a healthy weight.[15]

In one study of overweight people found that just increasing protein to 30 can help to lose almost 1 pound per week. They just add more protein to their diet, but they did not restrict anything intentionally.

Protein can also prevent weight regain by 50% and the rest 50% weight regain is fat-free muscle gain.  

How much protein should we eat for weight loss per day?

Recommended Dietary Allowance (RDA) for protein by the Institute of Medicine (IOM),

Males
14–18 years52.0
19–70 years and older56.0
Females
14–70 years and older46.0

Although this value can prevent protein deficiency and not fixed. It is way lower than a sufficient amount of protein for weight loss and body composition. It can be changed based on your activity level, age, sex, etc. 

Eating 30% calories from protein is optimal for weight loss and to maintain a healthy weight.

What do the studies say?

  • According to the 2015–2020 Dietary Guidelines for Americans the optimal protein intake is 10-35% is considered optimal for weight loss and other health benefits.
  • A study has shown that getting 30% calories from protein can boost metabolism by 80-90calories per day. Yet this contribution may not look significant if it compares with reducing appetite and increase satiety.[16][17]
  • Another study showed that eating 25% of calories from protein can reduce carving by 60%.
  • Eating 30% calories helps to eat 441 fewer calories per day and helps in losing weight almost one pound per week- by just adding protein to the diet.[18]
  • A 2016 study recommends that people should eat 1g protein per kg body weight with sedentary, 1.6g protein per kg body weight with moderate lifestyle, and 1.6g protein per kg body weight with intense physical activity to prevent muscle loss. And adults can eat 2g protein per kg bodyweight for the long term and can tolerate upper limit 3.5g protein per kg body weight.

The exact amount of protein should eat based on studies

It is cleared with these studies that 30% of calories from protein is optimal and healthy for weight loss.

Amount Based on calories

30% of calories mean if you eat 2000 calories per day you need to eat 600 calories from protein.

1g of protein provides 4 calories means 600 calories would have been provided by 150g protein. So you need to eat 150g protein.

For simple understanding multiply your total daily calorie intake by 30/400= 0.075.

Amount Based on body weight

You can also eat protein based on your weight. Just eat 1.5-2.2g protein per kg of your weight. 

If you are a 60kg person eat 90-130g protein. If your lifestyle sedentary starts with a minimal 90g limit to above.

These numbers aren’t too accurate protein intake 25-35% or 90-150of calories can be effective.
