How protein affects these pathways
Protein has a unique effect on these hormonal pathways. Unlike carbohydrates and fats, which are digested relatively quickly, protein takes longer to break down. This slower digestion rate leads to a more gradual release of ghrelin, helping you feel full for longer.
Moreover, protein-rich foods stimulate a quicker release of leptin and PYY. This is especially true for vegan high-protein meals, which often contain plant-based proteins that are rich in fibre, further enhancing the feeling of fullness.
The Thermic Effect of Protein
Protein has a higher thermic effect compared to fats and carbohydrates. This means your body uses more energy to digest, absorb, and metabolise protein.
While this is often cited in discussions about weight management, it's important to note that the thermic effect is just one small piece of a much larger puzzle. It's not a silver bullet for weight loss or management, and its impact is relatively minimal when compared to other factors like overall caloric intake, the quality of your diet, and physical activity.
