Beware of These Surprising Foods That Slow Down Your Metabolism, Say Dietitians.

Dietitians warn that seemingly healthy foods like fruit juice and granola bars can actually slow down your metabolism and hinder weight loss efforts. Fruit juice is often loaded with artificial sugar and lacks fiber, causing insulin surges and inflammation. Granola bars contain added sugars and refined carbohydrates that are damaging to your metabolism and gut health. Instead, opt for unsweetened beverages and fat-burning nuts and fruits to increase your metabolism and caloric rate.
