Does jogging in hot weather increase your weight loss?

Water balance. Exercise in hot weather will make you sweat more. This level of water loss/dehydration may give you a temporary weight loss, but this will go away after hydration. Probably best not to overfocus on day to day/hour to hour weight, and focus on the bigger picture of your overall health: exercise (strength, endurance, flexibility), diet, hydration, stress reduction, etc.
