First of all, how tall are you and how much do you weigh? When someone says they "look huge!!!" that is a big red flag unless I know more info. Anorexia
is a "body image" problem more than just an eating problem.
Second, you need to be eating 1500-2000 calories per day or your body will go into starvation
mode and conserve your calories by making fat... kinda the opposite of what you are trying to achieve. The ideal way of taking in those calories is to spread them out throughout the day... three meals with two snacks. That keeps all your body systems functioning well throughout the day...
Third, once you cut your calories to a healthy well balanced limit... then the idea is to add aerobic exercise
. Walking 30-45 min each day is plenty provided you get your heart pumping good.
And lastly, make sure you drink lots of water... water flushes out the body of waste. If you get dehydrated, you will lose "weight" but your body will begin to conserve functions and shut down... that's bad.
If you truly want to be "thin", then talk with a professional dietitian and your doctor who can help you guide your healthy eating....
Hope this helps Peace
