what can and cant i eat on a diet?

Answer 1

there is nothing you cant eat. BUT you have to count calories and e.g. one meal at McDonalds contains as much calories as healthy food for a whole day.
find calorie/fitness calculator on the net, enter your stats and it will tell you how many calories a day you need to maintain your weight. take 300-400calories off that number and that's how much you need to lose weight.
eat 5-6 small meals a day instead of 3 big ones.
5-8 servings of fruit and vegetables a day.
8 glasses of water a day.
4-6 times a week cardio work out for 30-50min plus light weight training.
no junk food, no sodas, no white flour (white bread, pasta, cookies, cakes etc)
