Foods to carry with you:
Here's a killer (and cheap) breakfast with lots of calories:
-1 cup oats
-4 tbsp peanut butter
-8-12oz cottage cheese
-1 or 1.5 scoops whey
Or, for low carbs, just eat a shitload of eggs with peanut butter and cottage cheese mixed in.
Can of salmon
2 scoops of whey
Honest to god, it's good. Add in a vegetable if possible or piece of fruit if it's impossible to go with a leafy green.
Another option: Peanut butter and lettuce sandwiches. Or just do peanut butter with whatever the hell you want. You're 6'2 and 168lbs.
steak, blahblahblah, vegetables.
Get a lot of sleep.
On the breakfast thing:
Cook oatmeal with peanut butter in it (I sometimes even preheat the peanut butter). Stir. Mix in cottage cheese. Mix in whey. NOM.
You're 6'2" and 168. You just need to focus on getting the calories in. Shit, hit up the fast food with your buddies but just be sensible about it.
