There are drugs available (Rxhealth even carries some) that is approved in Europe but not in the States. One problem; they don;t really work. The desire for food is too powerful. There is only one powerful tool -- your mind. You must practice using will power to eat less and eat wise choices.
You can't starve yourself thinner. But you don't need as much food as you think. Cut just 500 bullshit calories out each day and increase the amount of sets and the decrease the time in-between them. It's the only thing that works.
ZIP will help a little too. : ) Seriously, only because it supports the thyroid, which is the furnace that uses fat for fuel. But it still comes down to calories.
