Protein and Weight Loss
Some researchers have suggested that increasing the amount of protein in the diet may help with weight loss.
How? The mechanism for this may lay in 2 properties of protein
Firstly, protein has a high satiety factor. That is, it tends to fill you up and keep you satisfied for longer than if you had a meal based on fat or carbohydrate.
Secondly, it takes more energy for protein to be digested and metabolised by the body, compared with carbohydrate and fat. This energy expenditure is known as the thermic effect of food or dietary induced thermogenesis (DIT). Theoretically, consuming more protein will increase this aspect of energy expenditure and hence increase overall daily energy expenditure.
Therefore, diets that are high in protein may help promote a sustained reduction in energy intake and increase energy expenditure, which may prove beneficial for weight loss.
Further work is needed to establish whether high proteins diets pose long-term health risks.
