Sweating in not an indication of calories burned. It is the body's way of regulating your temperature. As far as I know there have been no long term scientific studies proving the human body burns more or less calories due to Food/Drink temperature.

Don't complicate things. Calories in vs calories out period.

Whatever the case is, I guarantee that teh tarik (Pffffft less sugar is still sugar & condensed milk which are alot of calories) you drink is more calories than any teeny tiny un-calculable calories you might or might not burn from the minuscule increase in body temperature. You want to burn enough calories to burn the calories in that teh tarik (easily 100-200 calories depending on amount of sugar/milk & size of glass) then go for a 20-30 minute brisk walk.
