no more carbs. Eat lots of veggies,
one portion of fruit only,
one handful of raw nuts, low fat dairy, high fat fish, lean meat. The increase in protein will keep you from getting hungry and on the long term completely abolish any cravings. Also, no deep frying, no butter, but olive oil and canola instead. No more rice, pasta, potatoes, flour....
My Dad eats that way for 5 yearsby now, is very healthy and lost 30 kgs during the first year.
Good luck!
