Each peeled lychee is about 6 calories, which makes the bowl the real serving size. On the energy-density scale, 66 kcal per 100 g puts lychees at the low end.

A typical serving (1 lychee, 10 g) has about 6 calories, and 100 g has 66 kcal. Calories scale with weight, so double the portion means double the number.
There are 0.8 g of protein in 100 g of lychees, which works out to about 0.1 g per serving (1 lychee). Treat it as an energy source rather than a protein source.
Sugar comes to 15.2 g per 100 g, so 1 lychee (10 g) delivers roughly 1 g. That sugar is already counted inside the calorie figures on this page.
Every value on this page comes from USDA FoodData Central, entry 169086 (SR Legacy). Serving figures are converted from the per-100-g data, so rounding can shift a total by a calorie or two.
