What is watermelon · 92% water

READ THE ORIGINAL

Watermelon is about 92% water, so although its sugar reaches the blood quickly, the total in one serving is small, and its real effect on blood sugar is modest. The chapter on why watermelon barely moves blood sugar works through that arithmetic step by step.

The water is also why it tastes very sweet yet is very low in calories: only about 30 kcal per 100 g. The gap between feeling like you ate a lot and not actually taking in much energy is exactly what makes watermelon satisfying.

The red of red-fleshed watermelon comes from lycopene, the same pigment that makes tomatoes red. Yellow-fleshed watermelon has almost no lycopene, and its other nutrients are much the same. If lycopene matters to you, choose red.
