Below are Dr. Fuhrman’s arguments against some of the most popular diets:
Gluten-free diet: While those with gluten sensitivity or Celiac disease should avoid eating gluten, Dr. Fuhrman believes that this diet’s success is grossly exaggerated. Most people on gluten-free diets end up eating high-glycemic foods, like potato flour or rice flour, that pump up your blood sugar and insulin, promoting weight gain.
High-protein diet: Certain studies have linked high-protein diets to an increased risk of diabetes and weight gain. Additionally, a high level of protein promotes the hormone called IGF-1, insulin-growth factor 1, which is linked to breast and colon cancers. Too much protein can also be hard on the kidneys.
Low-carb diet: A low-carb diet causes overeating because you’re never full or satisfied. According to Dr. Fuhrman, cutting out carbohydrates can be destructive for your overall health; it triggers the excess production of chemicals called ketone bodies, which leaves acids in your tissues and can trigger electrolyte shifts in your body, putting your heart at risk.
Fat-free diet: Because fat is essential to nutrient absorption, avoiding fat altogether can lead to more cravings and weight gain.
Low-calorie diet: Dr. Fuhrman equates this kind of diet to asking your body to breathe less oxygen – it’s not sustainable and is a formula for failure. Cutting back on too many calories creates nutrient deficiencies, which causes a higher degree of cravings.
