Answer:
I don't think it is possible.
Explanation:
You can loose weight by not consuming anything (not receiving proper nutrition) and it can be damaging to the body. Also without the proper nutrients is would be hard to maintain fitness because you would lack energy and could get more cramps.
Starving (another way not to get nutrition) to lose weight makes your body more likely, in the long run, to replenish fat. It uses the new basal metabolic rate from starvation mode. Lean individuals were more likely to gain more fat after starvation
C.pump blood more efficiently
Well, it depends on the context and the severity. If they are mad at you when doing it, it could be considered abuse, especially if there are marks on your body from it. If it is jokingly or sarcastic, then no. Clothes hangers and fly swatters don't seem that bad, but of course, I am not you, nor am I in your situation. You won't get much help if you have no proof, so you would have to have maybe some marks or a video or sound recording. Every police officer and social worker has different opinions though, so you could get help from one with no proof and you could not get help from one even if you have proof. I would say, think wisely about what you will do about it and balance the pros and cons before you act on it.
Hope this helps and if you have any other questions please let me know :)
