Your body literally cannot “try to keep you warm” other than shivering etc which yes burns more calories. Our bodies can cool us down but not heat us up. I don’t think anything can heat itself up in the same general sort of way that we can cool ourselves down.
Turns out, hot weather causes a greater calorie burn than cold weather. “In general, you burn more calories when you are hot (or in hot, humid weather) because your cardiovascular system has to do more work to pump blood
All I know is that military rations for Artic weather have about double the amount of calories as the standard ones.
Never heard of hot weather rations being any different to standard though.

A calorie is a measure of energy. It’s the energy one needs to raise the temperature of one litre of water by one degree Celsius.
When you’re cold, your body is actively heating many liters of water inside your body by many degrees Celsius, to maintain body temperature.
I googled it.

I believe I saw a video showing that if you are shivering it burns more energy than if you were doing a workout.
Calories are heat. You either sweat, breath or pee out your calories.
If you are in the cold the body works harder to keep you warm which burns more calories.
Tried Ai, this is what I got
At rest: Cold burns more calories.
During moderate workouts: Hot might burn a bit more due to cooling demands.
During intense workouts: Cold may win, since you can often perform better and go harder without overheating.
