Yes, hot weather always knocks my appetite down! Especially when it's muggy - feels soooo oppressive. Who wants to eat then?

Also ketosis kills my appetite and I also struggle to get the foods in that I should. I've started supplimenting with Atkins shakes. I try to get 4 or 5 small "feedings" in a day, with a shake being one of them. Even when I'm hungry, I can't eat much at one sitting.

I agree, try to find shakes, smoothies, or other hot-weather treats that you will find refreshing & enjoy enough to try and push your intake back up.
