Protein
Protein is one of the three macronutrients and plays a central role in appetite control and body composition.
Protein helps you feel full and reduces overall food intake. It also supports muscle maintenance during weight loss. Including enough protein in meals can improve consistency and control. This makes it easier to stay within your target intake.
