I’m honestly curious, do you snack a lot or something? Where do your calories come from?
I looked up a few frozen pizzas you can get in my area and they are around 800-900 kcal. Assuming you eat 3/8 per meal, that’s 9/8 a day, or up to about 1000 kcal. On the basis that you average a similar amount of calories per meal and consume the usual three meals.
The average man needs between 2000 and 3000 kcal. Woman start at 1600.
Since I gun for at least 2800 kcal and my average breakfast is about 600 kcal, my other meals need to be ~1200 kcal (1.3-1.5 pizzas). I never eat outside of meals except for maybe once over the weekend.
