First off....throwing up doesn't cause one to loose weight.....research it....but the calories go in almost immediately.

The best way is to take that 5 minute hike......as your starting point....then increase if daily or as rapidly as your body allows.....& you will be surprised just how much the exercise does wear off the lbs.....also not eating any junk food.....& starches/sugars....keep those out of your diet.....eat the healthy food that doesn't taste that good, but it good for you.

Eating smaller meals of healthy food more times a day....sometimes helps. I have struggled with anorexia....so my bad....I usually only eat one meal a day.....but if I bring any snack food in the house & eat it.....the weight goes on. I know because I only go shopping once a month....& when I buy junk food it's gone within the first 2 weeks of the month....making the last 2 weeks of the month the healthy weeks & I usually loose any weight I gained the first 2 weeks.

Also....don't know what meds you are on.....but AD's do cause weight gain because of the decrease in the metabolism.....that's sadly just a fact that has to be dealt with & countered with healthier foods & exercise. It does work......& from a personal experience.....ED's of any sort aren't something to get involved with.....as they cause horrible other problems that one has to live with the rest of their life & there is nothing worse than sitting there in older age saying....."If only I hadn't......."
