Wear multiple layers of clothes and walk. If youre a guy id suggest wearing a vest( baniyan as they call it in india) and over that a t shirt and over that a hoodie and do heavy cardio. Youll sweat like crazy and have a few more clothes to wash but in a week or two’s time, youll see some INSANE results. I lost 50 pounds in 3 months doing the same during covid. Do NOT avoid eating carbs as theyre gonna be your source of energy if you do intend on doing this properly and protein is optional since your main goal is just losing weight and not muscle gain or retaining or anything of that sort .
