Lost 20kg in 3 months!

Hey!
How did yu lose 20kg so quickly? xx

I lost 20 kg eating 1200kcal/day (which is the minimum kcal/day a healthy diet can be) with a daily requisite of 2.900. The caloric deficit is enough to be losing 1,7 kg each week XD

Now I just want to lose 5 more kg and I'm done!

its just a matter of self control, eating healthy and doing some exercise (also went to the gim like 45 min 5 days a week)
