Is watermelon good for weight loss?

This combination of moderate calories and genuine nutritional value is exactly what sustainable Indian dieting looks like.

How to reduce calories when eating watermelon
The ultimate volume snack. 500g watermelon = 150 cal. That is a LOT of food for very few calories. It fills your stomach with water and fibre, leaving less room for high-calorie snacks.
Replace afternoon biscuits with watermelon. 500g watermelon (150 cal) vs 4 biscuits (200 cal). More food, fewer calories, better hydration. An easy swap during summer.
Skip the watermelon juice. Eating watermelon: 30 cal/100g with fibre and chewing time. Drinking watermelon juice: 35 cal/100ml but you consume 300ml (105 cal) in seconds. Always eat, don’t drink.
Add a pinch of salt. Salt enhances the sweetness and adds electrolytes for hydration. Zero extra calories for a significant taste improvement.
