I began my new way of eating about 4 weeks ago so I'm no expert by any means but I can recognize my friends problem. She is following the "diet plan" of a local weight loss clinic. She is currently 5' even and 135 lbs. and they have her eating 1000 calories per day and limited to 16 grams of fat. This clinic has in no way educated her on healthy fats or eating a balanced diet. 1000 calories is way too low for anybody. She was excited to tell me today that she's only had 700 calories the past few days but is upset that she's been stuck at her present weight for a month now. I told her that intake is way too low but she's going to listen to these "doctors" and not me (who has 50 lbs to lose). She is severely undernourishing herself and could do some damage. Any advice on how to help her realize this is not good?
