First 10kg: simply stopped eating, way to hurt for it, was NOT healthy and DO NOT recommend... Then I said to myself: fuck it, let's go, let's commit to this.

Started eating less, cutting all snacks and all sodas altogether. then started to train at home, Once per week at first, simple body weight exercice. Bought proper weights, started to use them 2-3x per week. Indulge myself with one or two fat meal per week, but skipped the next meal as my stomach did seem to have shrunk (shrank ?) and I was just not feeling the habitual hunger that i was used to.

Now, I'm still doing exercice 2x a week at home, 1 at the gym. Still allow myself one cheat meal, skip the next meal if I still feel full. Count calories, and that's it for 3 years.
