There are dozens, perhaps hundreds, of different ideas about what <b>kinds</b> of foods affect weight management. Eating or refraining from eating such foods is supposed to promote weight loss or gain without struggle. I've experimented with an embarrassingly large number of the candidates:

alcohol, almonds, animal products, brazil nuts, cabbage soup, carbohydrates, cilled and frozen foods, chocolate, cider vinegar, combinations of fruits and vegetables, dairy, eggs, fish, goose liver, grapefruit, hot peppers, leaves, lettuce, lipids, martini olives, mustard, peanuts, porridge and gruel, potatoes, probiotics, processed foods, proteins, radishes, rice, shrimp, solanaceous plants, soup in general, sugar, supplements, tea, water, white bread, whole grains.

I'm happy to believe that every one of these foods helps somebody with weight management, but that somebody is not me. No food or combination of foods has ever helped me with weight management for long.
