Tips for loosing weight 
Though Not experienced 
I went to shimla n leh and still didn’t lose weight
may be consistent and constant exposure needed
I live in Shimla And Guess what I am Not gaining Over 61 
I eat a lot sab Lag Jata
I was in russia for 6 yrs , I gained alot of weight
1 hour of what excercise?
Casual walking or full-on swimming?
Increased appetite and craving for hot spicy foods in this temperature will counteract all the weight loss by shivering
