Highlights
•
The DIETFITS trial ended the macronutrient wars — diet quality matters more than the ratio of fat to carbs
Gardner presents his landmark trial: 609 participants randomized to healthy low-fat or healthy low-carb diets for 12 months. Result: no difference in weight loss. The emphasis on healthy in both diets — eating real food — was the actual intervention.•
Personalized nutrition is real but not in the way the diet industry claims — genetics explain very little of individual diet response
Gardner tested whether genetic markers or insulin levels predicted diet response. They did not. The personalized nutrition narrative — find your optimal diet through genetic testing — is not supported by current evidence.Was this useful?
