I go to a nutritionist, she gives me a very detailed and strict menu for a week, basically no white flour AT ALL, no fat (oils, mayonnaise, margarine, etc, no shrimps, only fresh cheese, no creams, no processed meat, no carrots, potatoes, abocado, onions, soy, garlic, no sugar (only fructose like Splenda), milk with 1% fat...
1 example of a day would be, breakfast, 1 cup of cereal with 1 cup of milk and THATS it, meal, 150 grams of meat with steamed vegetables and 1 glass of juice, dinner, 1 slice of bread (non white bread) with 30 grams of fresh non fat cheese and 1 cup of beans.
