Either prepare food in advance (best option) or bring protein bars or shakes with you when you go places. At last resort, 7-11 has tuna sanndwiches on wheat bread that are really tastey, and Carl’s has some good chicken sandwiches as well.
Bro at that age anything you eat your body will use as energy or to re build your muscle so this is what i say any time you see food you eat it. If your not hungery you eat anyways because in 15 mins from that point in time you will be hungery and its a damb good thing you just ate another sandwitch if ya know what i mean.
so stick to the basics carry around a bar and a weight gain shake so you can down some calories at any time. if you get hungery eat a double big mac or go the a graocery store and eat a liter of yogurt. there is no excuse for not eating unless your at a funeral then you can take a break
