Does A Low-Carb Or Low-Fat Diet Promote Longevity?

The debate over which diet is best for overall health and longevity has been ongoing for decades. Two popular dietary approaches that have received much attention in recent years are low-carb and low-fat diets. Both diets have their respective proponents, but which is the better option for living a longer, healthier life?

Low-Carb Diets: What Are They?

According to Melissa Prest, D.C.N., R.D.N., a member of the Prevention Medical Review Board and national media spokesperson for the Academy of Nutrition and Dietetics, a low-carb diet typically involves restricting the amount of carbohydrates consumed and focusing on foods that are rich in protein or fat. Keri Gans, M.S., R.D., author of The Small Change Diet, adds that a low-carb diet is generally defined as one where carbohydrates make up less than 45% of total calories.

Low-Fat Diet: What Is It?

According to Keri Gans, M.S., R.D., a low-fat diet is typically characterized by restricting fat intake to less than 30% of total calories consumed. However, Gans points out that the exact percentages may differ depending on the specific dietary approach being followed. Melissa Prest, D.C.N., R.D.N., explains that a low-fat diet aims to limit consumption of high-fat foods and prioritize foods that are higher in carbohydrates and protein.

Is A Low-Fat Diet Better For Longevity Than A Low-Carb Diet?

According to a study, A low-fat diet incorporating plant-based foods may help people live longer than a low-carb diet. However, it’s essential to make intelligent food choices within each diet. High-fiber carbs like oats, beans, and whole grains offer health benefits like lowering cholesterol, while foods high in saturated fat, such as red meat, butter, and fried foods, should be limited to reduce the risk of heart disease.
