So I'm a male, Caucasian, and almost 17 years old. I weigh about 130 kilograms (I know, it's a lot) and am about 1.87 metres tall, so that clocks my BMI in at a whopping 37 kg/m2, which means I am Obese Class II, so "Severely Obese" (according to Wikipedia). I really do want to lose this weight, at least get to just Overweight level (BMI of at most 30, so for my height this would mean a weight of no more than 105 kilograms), never mind Normal level. I was wondering if this would be possible to do in around 3 months? I'm willing to try any "extreme" diets (I've tried them before and absolutely no harm came to my body nor to my mental state. The only reason I keep putting on weight is because of exams) but not anything that involves "miracle pills" because those really are dangerous and they don't work. Bulimia is off the table too, as it should be. Before anyone asks, no I don't look like a human beach ball, despite my enormous weight. Still, I really want to lose this weight before I start Year 13 (or maybe, if doing it in 3 months isn't possible, at least by the end of 2019). Any tips or suggestions would be extremely appreciated!
