‘Proof’ it’s fats, not carbs, that cause weight gain – but only in mice
“Fat consumption is the only cause of weight gain!” declares the Mail Online, reporting on a study where mice were exposed to different diets and monitored for weight gain and increased energy intake.
Around 30 different diets, all highly controlled, were given to mice over a period of 12 weeks.
The diets varied in the amount of carbohydrate, fat and protein they contained. The mice’s body composition and food intake was measured every day.
