Which groups would benefit most from additional protein?

Individuals trying to lose weight would benefit most from additional protein because protein plays a significant role in weight management. Consuming a higher protein diet can aid in several ways: it enhances feelings of fullness and satiety, which can help reduce overall calorie intake, making it easier to lose weight. Protein also has a higher thermic effect compared to fats and carbohydrates, meaning it requires more energy for digestion and metabolism, thereby supporting a higher calorie burn. Furthermore, adequate protein intake can help preserve lean muscle mass during weight loss, as maintaining muscle is essential for sustaining a healthy metabolism.

The other groups mentioned don't typically require additional protein as part of their specific goals or dietary habits. For example, inactive individuals may not need as much protein since they may not be utilizing their muscles to the same extent as those who are active. Similarly, those focused solely on cardio may not require increased protein intake since their energy needs and muscle repair requirements differ from those engaged in strength training. Those consuming primarily starchy foods may not specifically require additional protein, especially if their overall diet is balanced. The emphasis on weight loss and the critical role of protein in this context makes the first option the most beneficial choice.
