Energy expenditure is the amount of energy that a body requires to perform physical activities such as movement, blood circulation, breathing, exercise and digestion of food.
A recent research study published in The American Journal of Clinical Nutrition has tried to study the impact of over consuming of macronutrients (carbohydrates, fats and proteins) on energy expenditure.
The study was conducted on 25 people who over-consumed macronutrients for 56 days. They were provided with three categories of proteins - 5, 15 and 25 per cent and their energy expenditure were monitored during activity and sleep.
The results have shown that people who consumed a high protein diet had high energy expenditure during both activity and sleep. People who consumed a low protein and high-fat diet had normal energy expenditure during activity but low ewenditure during sleep. Also, the muscle mass increased in people on a high protein diet and reduced in low protein diet people. People who were on a normal protein diet had normal energy expenditure and muscle mass.
