I started doing that last week. I only drink water! I have as much protien as possible via shakes and yard bird. I dont do fast food with the exception of mcdonalds grilled asian salad!
I try to cook everything vs buying it cooked, I do as little bread as possible,
Snacks. Try celery, apples, oranges, bananas, yogurt, carrots,
a tiny side salad (watch the dressing though) -
Drink more water, if you get hungry, pop a top - I carry a case of water in my car so i dont have to stop and buy water at 1.00 + a pop.
Red meat is good protien but bad for your heart and testies - (i stay away, its hard)
You have to hit it hard and stay focused! Hang around people that have the same goals as you, not people that wanna ride out to the bar all day everyday, you drink, get hungry and eat whatever..
Good luck sista
