A typical serving (1 slice (1/6 of 17-oz cake), 80 g) has about 257 calories, and 100 g has 321 kcal. Calories scale with weight, so double the portion means double the number.
There are 5.5 g of protein in 100 g of cheesecake, which works out to about 4.4 g per serving (1 slice). Treat it as an energy source rather than a protein source.
Sugar comes to 21.8 g per 100 g, so 1 slice (80 g) delivers roughly 17 g. That sugar is already counted inside the calorie figures on this page.
Every value on this page comes from USDA FoodData Central, entry 172711 (SR Legacy). Serving figures are converted from the per-100-g data, so rounding can shift a total by a calorie or two.
