Eating "big meals" doesn't meen anything. You need to learn how to count macros...
You weigh 160lbs
1g of protein = 4 calories
1g of carbs = 4 calories
1g of fat = 9 calories
I eat in a 40 40 20 split
Try similar for yourself
Thats 40% of my cals is from protein, 40% is from carbs, and 20% is from fats
Do some math...and like magic...you have a diet. Good luck.
