I eat less...don't even think about food for the most part. Every spring and summer I'll lose 10-15 pounds just from lack of appetite (which I gain back in the fall and winter because all I do is stay inside and eat carbs). I also tend to eat more salads and fruit in the warmer months so that accounts for some of the weight loss too. Sometimes I don't know which starts which---do I eat less because I'm manic or do I get manic because I'm eating less? The chicken or the egg? Same thing with caffeine.
