That's exactly what happened to me when I started. "You'll ruin your liver", "It'll put you in the hospital". When I replied back that my doctor is the one who suggested it then they usually shut up. I've learned not to try to get encouragement from my real life friends because it just isn't going to happen. I'm not sure if it's psychological or what, but from my experience, not many people that I know are jumping up and down because of my weight loss.
Just hang out in here, girlie. This forum is INDESPENSIBLE to me, without the encouragement and girls in here I KNOW I'd be back to my old ways. Setting goals and being accountable for the exercise and food that I eat has really meant a lot. Do what's right for you and if you have concerns about the diet then ask any of the members here if it's happened to them or consult a physician with your concerns
