This happens because resistance train stimulates muscle protein synthesis, as does an increased intake of high-quality protein ( 6, 7 ). As mentioned before, protein shakes provide amino acids that are easily absorbed by your body. Researchers believe that their inhalation increases amino acerb levels in the bloodstream, which in turn triggers a more significant reception for muscle synthesis ( 8, 9, 10 ).

Protein seems to influence their production. Both PYY and GLP-1 are hunger-reducing hormones, and studies show that high protein diets increase levels of each after a meal ( 14, 15 16, 17, 18 ). PYY and GLP-1 act by reducing your appetite, and GLP-1 besides delays the empty of your stomach ’ south contents. therefore, both hormones lead to increased feelings of comprehensiveness ( 19 ). What ’ s more, tell suggests that protein may besides reduce levels of ghrelin, a hormone that stimulates appetite ( 20, 21 ). While most studies use food, these appetite-controlling effects have besides been seen when testing supplements ( 22 ). For exemplar, one study in 18 women determined that drinking a whey protein beverage lowered ghrelin levels and increased PYY and GLP-1 levels, compared with the control group ( 23 ) .
Boosts your metabolism
high protein diets besides increase energy outgo — the calories you burn — in two different ways. first, your body burns more calories by metabolizing protein than carbs or fat.

DIT indicates the come of energy needed to metabolize each alimentary relative to the number of calories ingested. Its values for protein range from 15–30 % in contrast to 5–10 % for carbs and 0–3 % for fat ( 24 ).
Second, high protein diets stimulate gluconeogenesis — the serve of producing glucose from proteins or fats in the absence of carbs — which is believed to burn excess calories in the process ( 26, 27 ). In fact, one study in 10 healthy men reported a higher energy consumption in a high protein diet compared with the control condition, determining that 42 % of the increase was due to gluconeogenesis ( 28 ). consequently, increasing your protein intake through protein shakes and powders might help you take advantage of these metabolic effects .

In one study in 37 women, those who consumed an extra 40 grams of whey protein per day, showed a small decrease in abdominal fat compared with those who received a lower protein-quality append ( 33 ). similarly, a 23-week study determined that those who consumed an extra 56 grams of whey protein per day had lower body weight by 4 pounds ( 1.8 kilogram ) and lower body fat by 5 pounds ( 2.3 kilogram ), compared with the control group ( 34 ) .
