Consumption of whole-fat dairy foods (milk, cheese) does not promote long-term weight gain and may improve body composition by reducing fat mass and increasing lean body mass, contradicting the reductionist view that saturated fat and calories in dairy drive obesity.

You do not need to restrict yourself to low-fat or non-fat dairy to manage your weight. Current evidence suggests that whole-fat milk and cheese do not contribute to long-term weight gain, and yogurt consumption is actually linked to weight loss. Focus on consuming unsweetened, fermented dairy products like yogurt and cheese, as they appear to support healthy body composition by reducing fat mass and increasing lean mass.

GoodRefutesHIGH confidence
Based on the current science, dairy consumption is part of a healthy diet, without strong evidence to favor reduced-fat products... whole-fat dairy foods do not cause weight gain, that overall dairy consumption increases lean body mass and reduces body fat
