Bread Might Be Making You Gain Weight Even Without Eating More Calories

Researchers at Osaka Metropolitan University found mice preferred bread, rice, and wheat over chow and gained body fat even without eating more calories.

The mice showed lower energy expenditure, liver fat buildup, and other metabolic changes linked to the carbohydrate-rich diet.

When wheat flour was removed, the harmful effects reversed, suggesting staple carbohydrates can influence weight through metabolism, not just calorie intake.

The study could inform obesity research and future diet guidance on bread, rice, and wheat-based foods.
