My goodness! I was so shocked that someone could actually think that 350cals a day with so much exercise could be healthy for them. You obviously know about calories and stuff but u have absolutely NO IDEA of how such a ratio of food/exercise can and WILL damage ur internal organs. Yes, u can keep it going for maybe 24-48hrs but ur body will crash and u WILL at some stage collapse due to lack of nutrition and deficits in minerals and electrolytes paramount for life! Ur liver and kidneys will begin to work harder whhich will put stress on ur heart. Please wake up to this and prevent undue and preventable pain to urself and surrounding family. Trust me i do know what i am talking about- i am a nurse and see this sad and very preventable disease pretty much every day i am at work. Its something u need to deal with and confide in someone u trust- they can help u come up with a healthy strategy to lose weight but in a structured way. This not a cheap way out with what u r doing- it will prove more expensive then u think! I think its got to stop here and now and stop the cycle of pain and punishment to urself! Get healthy and a healthy body weight by seeing a nutritionist, seek out a gym or join a sport club. TIME is the key- no quick fix. My sister did exactly what u r doing now and trust me- it is sad, it is dangerous and the outcome is more then tragic. She lost her teeth (she is 26 and didnt throw up!) her hair is horrible, her skin is damaged and her organs are up the creek- she now experiences mini strokes due to this! I am not joking. Sad for her but also her family (she has 2 kids) and her parents and siblings because one day she will have a major stroke and unfort she wont recover and will never be able to play with her kids and witness them get married. WAKE UP AND GROW UP AND TACKLE UR ISSUES HEAD ON IN HEALTHY MANNER. Atleast u have a chance to recover, my sister doesnt!
