: Grams of protein vs calorie intake I am currently on the 5x5 program with the goal to get stronger. I understand that in order to achieve this goal one must consume a surplus of calories in order to actually gain the muscle.

Do understand that the 1g per pound total body weight is a rough guideline. It will give you more than your body's daily protein requirements. The excess is burned as energy. As a rough guideline:

a serving size of meat (beef, pork, chicken, fish) about the size of your closed fist contains roughly 20g of protein
a serving size of meet about the size of your open hand contains roughly 40g of protein.

Unless you are a big guy trying to lose weight, hitting your dietary protein requirements without breaking your calorie limits for the day is quite easy to do with real food. Protein shakes come to play when you need to increase your protein while still trying to stay below a Calorie limit.

That said, there are four things your muscles need to grow and get stronger:

Work: if you don't push yourself your body will never realize it needs to get stronger
Rest: the actual building happens when the muscle is in a relative state of rest. In fact sleep is when a lot of your strength gains actually happen.
Protein: Obviously, to create the protein pairs that help with contraction the body needs it's essential amino acids which come from various sources of protein.
Energy: Without sufficient energy to synthesize the proteins necessary for strength, the body won't be as efficient and you will have harder times getting stronger and keeping up with the program.

I already posted it as an answer on another question. The high protein needs are a myth to sell shakes. Well actually they are no myths but old research that is obsolete now.

Muscle mass and strength can be gained on a wide range of protein intakes, from as little as the RDA up to very large amounts. There is little support for the necessity of very high amounts, e.g. >2 g protein/kg body mass per d, for optimal muscle hyper-trophy during energy balance or excess. (source)

Maybe you need more protein than before, but even though you are probably extremely proud of your achievements, doing 5x5 still doesn't make you a professional athlete and keeps your needs well below the 2g/kg/day mark.

So to answer your question, you will probably burn more calories, it does not make a huge difference through which means you consume them, although I personally would recommend carbohydrates before exercise (or during prolonged cardio exercise). Always keep in mind that calories are a rough measurement at best.
If you consume less than your body needs, it will collect the energy from other sources, first of fat but at some point from the muscle mass itself.

How much your body really needs is hard to measure or estimate, instead of making calorie calculators the main guideline. I'd recommend listening to your body, when you are hungry: eat.
(granted you are not suffering from an eating disorder, have general weight problem or something comparable, of course)
