A typical serving (3 oz, 85 g) has about 84 calories, and 100 g has 99 kcal. Calories scale with weight, so double the portion means double the number.
There are 24 g of protein in 100 g of shrimp, which works out to about 20.4 g per serving (3 oz). That is a genuinely high protein share for the calories.
Yes. Carbohydrate is 0.2 g per 100 g, effectively nothing, so almost all the calories come from protein and fat.
