When to Pick Each

For Cutting / Weight Loss

When cutting on a tight calorie budget, Radish gives you 27 more calories of headroom per serving — that's room for an extra snack, more vegetables, or a higher-protein second portion. If protein density matters more (which it does for preserving muscle on a deficit), Radish delivers more grams of protein per calorie consumed.

For Bulking / Muscle Gain

For muscle gain, you want calories AND protein. Watermelon brings 46 calories — useful when you're chasing a surplus and struggling to eat enough. Watermelon delivers 0.9g of protein per serving, which directly feeds muscle protein synthesis. The best pick depends on whether you need more total calories or more usable protein.

For Keto / Low-Carb
