Are Bananas Good or Bad for Weight Loss?
Bananas have a mixed reputation in diet culture. Here’s the honest breakdown:
- In favor: At 105 calories, a banana is a moderate-calorie snack with real fiber (3.1g) and nutrients — far better than processed snacks of similar calories.
- Watch out for: Bananas are more calorie-dense than watery fruits like watermelon or berries, so portion awareness matters if you’re eating several per day.
- Best use case: A great pre-workout snack or addition to oatmeal/smoothies, but not necessarily a “free” food to eat unlimited amounts of.
