Why Do We Need To Consume Protein to Lose Weight?
Protein is the single most important nutrient for weight loss and a better looking body. A high protein intake boost metabolism, reduces appetite and changes several weight- regulating hormones.
Our weight is actively regulated by our brain via hypothalamus. By replacing carbs and fats with proteins, it actually increases the levels of satiety hormones, while reducing the levels of hunger hormone. This leads to a major reduction in hunger and it can make you eat fewer calories automatically.
After we eat, some calories are used for the purpose of digesting and metabolizing the food. This is called the Thermic Effect of food. Protein has higher thermic effect (20- 30%) compared to carbs (5-10%) and fats (0-3%). About 20- 30% of protein calories are burned while the body is digesting and metabolizing the protein.
Due to high Thermic Effect and several other factors, a high protein intake tends to boost metabolism. It makes you burn more calories around the clock including during sleep!
