How high protein diet helps in weight loss?
- More calories burnt: Protein –rich diet boosts the metabolism levels. Digestion, absorption, and metabolism of proteins require more energy, which is obtained by burning more calories.
- Reduced appetite: Including more protein in the food makes you fell fuller and less hungry. Increased satiety levels make you consume less food and energy and help in weight loss.
- Optimize the amount of weight-regulating hormones: More protein intake results in an increase in satiety hormones and a decrease of hunger-causing hormones in the body.
According to a study published in the International Journal of Obesity, the effect of a high-protein diet on weight loss was examined in 932 obese families. The results indicated improved health parameters with a decrease in weight and body fat along with prevention of weight gain.
In another study conducted on 83 obese women, a protein-rich diet led to decrease in total body fat, waist circumference, lipids, glucose levels and blood pressure.
In addition to helping in losing weight, protein also helps in improving muscle mass, strength, and endurance.
Thus, it is also recommended for bodybuilding.
The daily requirement for protein is 0.8 grams per kilograms of body weight, to carry out the normal bodily functions. However, if one is aiming for weight loss or bodybuilding, an extra intake of protein is beneficial.
Below we provide a list of 11 foods which are proven to help in weight loss. You can either read about all of them or jump to the ones you love using the table of contents below:
Nutritious High Protein Foods For Weight Loss
Here are 11 Foods which are abundant in proteins and can help with your weight loss schedule.
Seafood is amongst the richest and healthiest protein sources. It includes various fishes, shrimps, prawns, crabs, and lobsters to name a few.
It is considered a complete and high-quality protein source as it contains all the essential amino acids, which are required by the body through diet. Additionally, it also contains many other nutrients and omega-3-fatty acids which are good for mental and cardiovascular health. As compared to other meats and poultry, the calories and fats in seafood are lesser, and the proteins in it are much more digestible.
A 100g serving of seafood provides about 29g protein, which depends on the type of seafood. However, most seafood is considered rich in protein. Fishes like tuna and salmon will provide 26-28g protein, shrimps and prawns provide 25g protein, crab offers 23g proteins while lobsters give about 20g protein.
In a study published in the International Journal of Obesity, it was found that inclusion of seafood as part of an energy-restricted diet plan facilitated much more weight loss than a diet without seafood.
What does this mean? Seafood comprising fish, shrimps, prawns, crabs, and lobsters is a rich, complete and high-quality protein source, offering 20-30g per 100g serving.
2. Lean meat-Chicken and Beef
Animal protein is one of the best, and complete sources of all the 8 essential amino acids required by the body to perform different functions. It is very fulfilling in nature and promotes satiety.
The complex proteins from animals require more energy to digest which results in more calories burnt. Lean meat is a very healthy source of animal protein which includes chicken breast and beef.
A 100g serving of beef will load the body with about 22g of protein, while chicken provides around 23g high-quality protein.
Research conducted on 61 women consuming either chicken (white meat) or beef (red meat) reported significant decreases in body fat and lipid levels in both the groups. This proves that both the types of animal proteins are suitable for weight loss.
What does this mean? Lean meats (meats with low-fat content) are excellent protein foods providing all the essential amino acids to the body. They can give you 20-25g protein in a 100g serving.
Eggs are very nutritious and contain protein at high levels. 12% of eggs constitute protein. They are commonly available and very versatile. They can be eaten in different forms and easily incorporated into dishes.

The egg yolk contains cholesterol which could be a concern for some people. However, egg increases the cholesterol in only some individuals, while in others, it does not.
The cholesterol in egg increases the HDL cholesterol (good cholesterol) in the body. Therefore, it is also beneficial to consume only egg whites which provide about 3.5g protein.
Journal of American College and Nutrition reports a study in which the effect of egg-based breakfast on 30 overweight subjects was examined. As a result, the food intake was decreased, and satiety levels were increased in the people after the breakfast.
In another study, egg-based diet promoted weight loss by a decline in body fat and waist circumference.
What does this mean? Eggs are highly nutritious and a must-have food to increase protein intake and promote weight loss.
Dairy products are an excellent source of protein obtained from animals, which can also be consumed by vegetarians.
Milk is considered a complete diet as it contains almost all nutrients required by the body. It contains high levels of protein. Two main types of proteins are present in milk- soluble (whey 20%) and insoluble (casein 80%).
One cup cow’s milk contains about 8g of protein. Milk helps you feel full and decrease the urge to eat. Several studies prove the effectiveness of dairy products in losing weight.

One can consume both low-fat and full-fat yogurt to aid in weight loss. Contrary to the belief that one should consume low-fat dairy products, consuming high-fat dairy is known to lower the risk of obesity.
What does this mean? Protein-rich yogurt should be added to the diet to facilitate weight loss and improve digestion.
6. Whey protein
Whey is another commonly used dairy protein that promotes weight loss.After curdling of milk to form cheese, the remaining liquid is whey.
Proteins are extracted from this liquid and are called whey proteins. They may be of different concentrations depending on the technique of extraction used. It is used to obtain whey powder (11-15% protein), whey concentrate (25-89% protein) and whey isolate (>90%).
Whey is a complete protein which has high levels of essential and branched chain amino acids, vitamins and minerals. Therefore, it is widely used in protein shakes, baked products, nutritional supplements and infant food.
What does this mean? Whey protein is a proven, complete and healthy protein-rich food for weight loss and management.

- Milk consists of the carbohydrate lactose, which can be difficult for some people to digest. Lactose intolerance is quite common around the world.
- One should not consume protein in exceptionally high amounts, more than the maximum prescribed or recommended limits. The body can absorb and digest only a specific amount of protein per day. Very high protein intake can lead to protein toxicity which can reduce the intake of vitamins and minerals by the body and cause disorders of kidney, liver, bone and digestive tract.
In the end..
High-protein foods help in weight loss by helping the body burn more calories and increasing the energy expenditure. They also decrease hunger and limit food intake by helping in the release of satiety hormones and making one feel fuller.
