Correct Answer is D
Explanation
A. Increasing intake of saturated fats and limiting fiber to reduce digestive stress: This promotes heart disease and insulin resistance. Saturated fats raise cholesterol, and fiber is beneficial, not harmful.
B. Consuming a high-protein, low-carbohydrate diet with minimal physical activity: Low activity and extreme diets can increase cardiovascular risk and insulin resistance long-term.
C. Relying on vitamin supplements and avoiding all sources of dietary fat: This ignores whole food nutrition. Some fats (e.g., omega-3s) are heart-healthy and essential for metabolic function.
