Why is protein so important?

Proteins are basic components of the human body, each cell contains them. Are used to produce muscles, tendons, organs, and skin, as well as enzymes, hormones, neurotransmitters, and various tiny molecules that serve many important functions.

In a study with 12 subjects who ate a high protein isocaloric diet (30% protein, 20% fat and 50% carbohydrates) for 12 weeks. Increased satiety, eating 441 fewer calories per day, lost 4.9 kilos and they also decreased fat.

Protein intake helps build and maintain muscle mass. Lean muscle mass burns more calories than fat, even when the body is at rest.

A diet low in fat and protein can lead to weight and muscle loss. Loss of muscle contribute to long-term weight gain.
