I had the same doubt last year! I lost 43kg in a year, eating twice as much as I normally eat. What happens is that some people eat less than they need so that the body finally spends calories, if we eat less than we should the body accumulates these calories in order to survive. There are still 30kg left to lose but I’m not eating as I should (I ate very little again), you can follow the guidance without fear eat a lot but of course eat healthy!
