Yes you need to stay out the sun
All living organisms carried out metabolism. Metabolism refers to a set of biochemical reactions on which the survival of the living organisms depend. Living organisms get energy from the food they eat to fuel the biochemical reactions. The majority of the energy needed in the body is derived from carbohydrates. When carbohydrate is eaten, it is broken down through the metabolic process of glycolysis and subsequent biochemical reactions and the final product is energy. This energy is then used for various purposes in the cell, especially to drive biochemical reactions and it can be transferred from one form to another.<span />

Answer:
I don't 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 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
