Sport calories come from protein ?

[viper]

How can you figure how how many calories come from protein ?

Calories: 150
Protein 10g

isn't it 10 into 150?

 

[JustaThought]

I believe each gram of protien is responsible for 4 calories.

Thats 1g proties = 4 calories

the rest is made up from your other ingredients

Yes, 4cals per gram of protein, so your food above has 40cals coming from protein, 110cals from carbs, fats, and alcohol.
