Pre-diabetic on antipsychotics: should I keep forcing big seasonal weight loss?

My weight currently fluctuates, by a difference of a gain or loss of fifteen kilograms. I lose that in cooler months and regain it in warmer months, as a side effect of my medication. There currently aren’t any antipsychotics that have been legally approved in Australia yet, only in the USA. I’m pre-diabetic and I’m fat. Should I keep doing this each autumn/winter, while I’m waiting for the weight loss drugs to be approved? It gets too hot to eat in spring and summer, to eat the amount of low fat foods it takes to lose weight.
