15 High Protein Vegetarian Sources for Weight Loss [Science Backed]

Plant-based foods are a complete protein source and as useful as animal protein for weight loss. Here we discuss 15 such foods which are rich in protein, fiber, and other nutrients, which make them ideal for weight loss by both vegetarians and non-vegetarians.

Dietary habits play a vital role in determining the weight of a person. Certain foods can help in increasing or decreasing the body weight. Thus, for losing weight, it is imperative to pay attention to eating patterns and the food consumed.

Protein is an essential nutrient for persons who are aiming at weight loss. Consumption of a high-protein diet is associated with weight loss as it helps in reducing the food intake by increasing satiety and decreasing hunger. Also, protein metabolism requires more energy which results in more calories burnt.

People often prefer animal sources of protein for weight loss as it is considered of high-quality. However, research has now proven that plant-based protein sources are as useful as animal protein in weight management.

Many plant-based foods are protein-rich and provide us with the essential amino acids required by the body from the diet. Therefore, it can be said that one can successfully achieve weight loss goals by opting for a vegetarian diet.

In studies, it was shown that a vegetarian diet is capable of providing the body with all the essential nutrients in the required amount at all stages of a person’s life and is also beneficial in the prevention of certain diseases.

A study published in the Journal of American Dietetic Association states that vegetarians have a lower BMI than non-vegetarians due to their eating habits. Vegetarian diets are not only nutrient-rich but also more beneficial than a non-vegetarian diet for weight loss.

This is because a diet containing animal protein does not lower the cholesterol levels and increases the risk of heart diseases. In contrast, a plant-based diet consisting of more proteins and fewer carbohydrates has lipid-lowering effects in addition to assisting in weight loss.

The efficacy and advantage of a plant-based diet over a non-vegetarian diet can be inferred from the fact that in several trials involving over a thousand individuals, it was found that people on a vegetarian diet experienced a significantly higher weight loss than persons on a non-vegetarian diet.
