Read what I just posted to you in your calories post. Honestly, I dont think atkins is effective. U cut out all carbs, which actually isnt healthy for you. .And basically u just eat the fatty foods etc.. . It might help u lose some weight at first and quick, but it most likely will come right back once u start eating carbs again. .And u cant cut out carbs forever...
And hun.. Trying to lose 20 lbs in 2 weeks.. Well thats being a little too hard on yourself. To do that u would have to prolly starve and please please dont do that to yourself.. Plus, u will feel worse because your body will go into starvation mode and u will just gain it back plus some and quicker then u think. (im not just talking out of my a$$ by the way..Ive had an eating disorder for 2 yrs now, and am trying to recover, but I talk to nutritionists all the time so im very aware of nutrition) you;d be surprised tho, if u start following a healthy meal plan, even if u only lose like 2-3 lbs in 2 weeks, u will feel better, and therefore look better also.
