10 kg is equal to how many calories?
If we follow the 3,500-kCal rule, 10kg would be 77,000kCal. So over 45-days that works out to around 1,700kCal burned per day. This is a lot to burn in a day so I recommended giving more time to burn that weight (most dietitians and nutritionist will recommend limiting yourself to burning 1000 per day).
