Does increased protein intake always correlate with fat loss?

Increased protein intake does not inherently guarantee fat loss; rather, it is contingent on total caloric intake. When managing weight, the balance of calories consumed versus calories burned plays a crucial role. If a person consumes more calories overall than they expend, regardless of whether those calories come from protein, carbohydrates, or fats, they are unlikely to achieve fat loss.

Protein can support weight loss due to its effects on satiety and its thermic effect, but these benefits are effective only within the context of a caloric deficit. If someone increases their protein consumption but also increases their total caloric intake or does not alter their caloric intake at all, fat loss may not occur. Therefore, while protein can be an important component of a diet aimed at weight loss, it is not the sole determining factor; total caloric balance is crucial in achieving fat loss.
