Are you gaining weight? If so, you're eating enough. If not, then you're not. Simple as that.
Im about 167, picking up weights again. Pretty Much at the skinny fat stage. Im tyring to put on some pounds, and im not sure if I am eating enough. I am a college student so it is hard to measure portions and calories from the school cafeterias.
Plate full of eggs, 3 strips of bacon, 20 oz of milk
3 chicken breasts, 4 boiled eggs. 20 0z of milk
whey protein and bcaa
meat, vegetables, 20 oz of milk
Chicken or turkey sandwich on wheat
If your eating clean it's pretty easy to not eat enough. When I bulk I just make sure I'm never hungry. If you want to be big you have to eat big!
I think its pretty decent for being in school.. If your not gaining weight try adding a bit more at each meal or adding in a few snacks throughout the day like protein bar, add another shake, yogurt, cottage cheese, fruits.
