This is LOOOONG after the last comment, but I think you could mention coconut milk as a very nice solution if people have any troubles with milk. I don’t have any digestion problems but I know that my skin doesn’t reaaaally enjoy lots of milk, which is quite a mark of non-tolerance.
Coconut milk is a bit heavier in fats but these are medium-chain saturated fats which are very good, and I believe whey or normal foods brings enough proteins anyway. My cans have % coconut+water, and casein. That’s 1000kcal a can… and still less than $3 for these
To be a great athlete you need to be able to sustain high forces (speed x strength = power). Bigger muscles can generate more power because they are capable of producing more force at a given speed. The higher your training intensity, the faster you deplete your body of carbohydrates, amino acids, fat, water and electrolytes. Your body’s nutritional priorities are replacing carbohydrates and amino acids. Failure to replace carbohydrates can cause your body to catabolize (break down) muscle tissue resulting in serious losses of muscle mass, strength, speed and power.
