High-protein diets include definitions of relative quantity (protein energy ratio) and absolute quantity (protein intake), with most high-protein diets referring to a dietary pattern in which daily protein intake exceeds 20% of total daily energy or 1.5 g/(kg-d), but generally does not exceed 30% of total daily energy or >2.0 g/(kg-d).
Several studies have confirmed that high-protein diets reduce hunger and increase satiety and resting energy expenditure. Since ingested protein cannot be stored by the body but needs to be metabolized and utilized immediately (including peptide synthesis, new protein synthesis, urea production and gluconeogenesis), the metabolism process requires a large amount of adenosine triphosphate (ATP).
High-protein diets can reduce body weight and improve a number of cardiovascular disease risk factors, including glucose homeostasis and lipid profiles. However, if you wish to implement a high-protein diet, please do so under the guidance of a physician to avoid overloading liver and kidney function with excessive protein consumption.
