Sweating itself burns almost no calories — it's your body cooling down, not the work. The calories come from the activity that made you sweat.

All values use the MET approach from the Compendium of Physical Activities (Ainsworth et al. 2011) and the ACSM formula. Figures are gross calories (including resting metabolism) — individual variation due to fitness level, technique, temperature, and metabolic efficiency can be ±20–30%.
For more precise measurements, heart-rate-based devices or lab testing (indirect calorimetry) are recommended.
Calories are burned primarily by physical work — muscles converting energy. Resting metabolism (Basal Metabolic Rate, BMR) accounts for 60–75% of an average adult's daily energy expenditure. Movement, exercise, and everyday activity (NEAT — Non-Exercise Activity Thermogenesis) make up the rest.
No single activity dramatically elevates burn in isolation — what matters is the sum of all activity throughout the day.

Yes. Many half-truths circulate about Sweating. The section above explains what the science actually says.
For some of these concepts (e.g. resting metabolism, muscle calories) weight does matter; for others (e.g. sweating) it barely does.
Combining cardiovascular exercise (running, cycling, swimming) with strength training and a moderate calorie deficit is the evidence-based approach.
