Which dietary strategy is linked to a longer lifespan?

• A. Daily carbohydrate intake
• B. Increasing protein intake
• C. Limiting daily energy intake
• D. All the above

Answer: (C)

Choosing to limit daily energy intake is associated with a longer lifespan due to its effects on metabolic processes and overall health. Caloric restriction, without malnutrition, has been widely studied and found to lead to various health benefits, including improved heart health, reduced risk of disease, enhanced cellular repair mechanisms, and potentially increased longevity. This strategy encourages the body to utilize its energy more efficiently and can lead to beneficial changes in hormone levels, inflammation reduction, and improved insulin sensitivity. In contrast, merely increasing carbohydrate or protein intake may not provide the same health benefits. While these macronutrients play essential roles in the diet, their intake is not directly linked to longevity outside the context of overall energy consumption. It's important to focus on a balanced diet that also considers the quality of calories consumed, rather than just the quantity or macronutrient focus.
