Do you think it is possible to lose weight and stay physically fit without receiving proper nutrition? Justify your response.
dlinn [17]

Answer:

I do not think it is possible. 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. If you don't have nutrition your hair,nails,bones and skin with become weak and you will feel drained and tired all the time. Yes you could lose weight but your body wouldn't be healthy.
