Deep dives

Dietary Protein and Satiety

Increased protein intake is believed to boost feelings of fullness through mechanisms like raised levels of gut-derived satiety hormones, increased energy expenditure, elevated amino acids in the blood, and higher gluconeogenesis. Dietary protein is essential for amino acids essential in physiological processes, with the recommended daily intake set at 0.8 grams per kilogram of body weight to prevent protein deficiency. Most adults, however, consume much more protein than the recommended amount.
