need help GAINING weight.

PLease go see a Dr and start eating HEALTHY no junk, eat normal just normal healthy foods 3-4 times a day.

This is why Starvation mode is bad.

and don't forget to eat the extra calories that you *earn* by doing excercise. If you were excercising and only eating 800 calories, you were pretty close to zero calories I bet. (Not good)

Look in community and add a lovely girl called 'audreyyrose' She herself was in a similar position to you and has regained her shape and a little bit of weight. She now looks and feels great slim and healthy not boney and skinny.
Good luck with your journey we are all behind you.

Some good advice here:) If you find you are unable or unwilling to stop exercising for the moment, I would avoid cardio at least and focus on strength, grace and flexibility. Try forms of exercise like Tai Chi, Chi gong, mild weight training, yoga etc.

Some foods such as raisins and crackers can be slipped into your diet here and there between meals to help increase your calorie intake.

Slow and steady is the best solution. I would highly recommend having a doctor or naturopath check you out and see if you are suffering from any nutritional deficiencies. Losing your hair is not unusual, and as you regain your health you will probably find that this stops soon.

Wish you luck. It's not too late to get back onto a healthier road!!

I'm glad you are ready to take better care of yourself. What you ought to do is reconfigure your goals, pretending that you weigh 115 lbs, and follow the recommended calorie intake for maintenance.

You should not have to focus on any particular food group, but instead be sure to include a variety of healthy and nutrition dense foods from all groups. Dairy, lean meats (or meatless proteins if you are vegetarian), plenty of vegetables and some fruits, and healthy fats like olive or canola oil, even real butter in moderation. Try natural nut butters with celery stalks, apple slices, or even rice cakes.

Your little stomach might be quite shrunken and will not like to feel overstuffed, so plan to start by not overdoing the fiber or veggies, so that you can meet your caloric needs with foods that have more calories per ounce. Gradually you will be able to eat normal amounts of food without feeling ill.

You've made a healthy decision! Best wishes to you.

(edited to include one more note: yes, you might have an eating disorder -- but you also might have just gone overboard dieting. If you do have a psychological issue, seek help from your doctor, for sure.)

Definitely get a doctors advice with this. There are a ton of different gainer protein shakes out there. Also go with calorie dense foods obviously.

See a doctor. Also, don't see a 'nutritionist', see a 'dietician'. Nutritionists do not have to be qualified and the word isn't protected, whereas dieticians must be qualified and not anyone can start calling themselves one. (Ben Goldacre - a science journalist - has a dead cat which is a 'certified nutritionist'!)

But overall, please see a doctor ASAP. We don't know anything other than your height and weight. They'll be able to see you in person and identify what exactly you're deficient in through your appearance or blood tests.

You may need therapy too. Although you may be able to gain it back easily in theory, the psychological component may make it harder to do so in practice. But best you go to see a doctor and get their advice, which should be superior to anyone on MFP.
