Hi! Everyone I know has a diminished appetite in hot weather and I've usually wanted to just snack on things like salads, fruits and meats in the summer and not each much at all. As soon as cool weather sets in, my appetite starts to rampage.

I also find I have other times when my appetite changes apparently for different reasons than weather, although they're unknown to me. Sometimes I eat like a fiend--other times I don't.

I'm wondering since you're having a hard time reaching a good calorie level if you might want to increase your fat intake a little here and there. Generally speaking, fat does tend to decrease appetite, but at the same time a little goes a long way toward increasing calories.
