do I need a lot of protein for a flat stomach?

Protein can help preserve lean mass, which means you have to lose less weight in the long run. Lifting also helps preserve lean mass.

I've been wondering since I never seem to hit enough protein.

You need a lot of protein and a lot of calories to support heavy-lifting to build the muscle that will make you look lean and taut once you lose enough fat to see the underlying muscle.

So in that way yes. That said just eating lots of protein alone won't do anything other than give you more calories.

Are you trying to build muscle or lose fat?

Trying to lose the fat on my stomach only

friend you can't spot reduce.

Impossible. Can't spot reduce. Losing fat is like trying to dry a sponge. Can't dry a corner when the rest is still wet. Your body decides where to burn it and there is no food or exercise that will make your body use up stomach fat first.

And what does protein do?

Sufficient protein is required to maintain or build muscle. At a caloric surplus you can build muscle, at caloric deficit you can only really maintain your muscle. General advice is 0.8g of protein per pound of lean mass.

So heavy lifting will give one a flat stomach?
And what does protein do?

I already answered both of these. Protein and lifting help you retain muscle which means you have to lose less weight in the long run. Either way if your body fat is high you will have to lose fat to have a flat stomach. If you are at a normal weight then heavy lifting is going to be very important. The most important factor is being patient.

If you have fat on your stomach, you have fat on the rest of your body. There is no way to spot reduce. Fat comes and goes where it wants and you have to eat a calorie deficit and get some strength training in (to not lose as much muscle) and eventually, after a very slow process, some of the fat will go away. On your entire body, including your stomach.

Bets way I can tell anyone to build muscle and lose fat is to lift heavy was doing no more than 30 minutes of cardio a day. Do to much cardio and your just burning away the cals your body needs to build muscle. Now this works for me. Dont know how it works for others. This is also why most body builders do very little cardio during training season.

Your stomach and 6 pack are made in the kitchen meaning your diet. Eat at a deficit. It has to come off eventually from your stomach. It just might come off other areas first and your stomach last. Keep doing weights they are important to keeping your muscle tone and will help hold everything together so you see results better. Plus they burn calories huge bonus. A good diet at a 500-calorie deficit, weights 3x a week, cardio 3x a week. That’s it. People just try and overcomplicate a very uncomplicated thing. Either that or they want an easy 30 day fix. That just isn't going to happen.
