Science behind weight loss, high-protein eating, and metabolism

A high-protein intake stimulates thermogenesis which in turn increases metabolism. It is because protein takes more energy to digest than fats or carbohydrates, resulting in an increase of calories burned even when at rest. According to a study in The American Journal of Clinical Nutrition, high-protein foods can increase the metabolism up to 80-100 cal per day.

Protein-rich foods also give you the feeling of being full, which reduces your appetite, and therefore, your calorie consumption. A study by the University of Washington School of Medicine found that people who ate 30% of their daily calories as protein consumed 441 less calories each day.

While the weight-loss benefits of high protein diets are obvious, excessive intake can lead to kidney problems or osteoporosis. Balance and moderation is key to incorporating high protein foods into your daily diet.

Getting Started: High-Protein Foods

Focus on lean protein sources like eggs, greek yogurt, tofu and lentils. Remember that all proteins are not created equally - you should also consider your source of protein. A study in The American Journal of Clinical Nutrition, for example, found that long-term plant-based protein consumption is healthier.
