try paleo diet for a month, around 1g of protein per 1lb of body weight, 80g of fat (nuts - not peanuts!, avocados, dark 85% cocoa chocolate, bit of peanut butter, coconut oil...) and carbs from green veg only (no potatoes, parsnips, carrots...). I lost around 30kg (obviously not in a month). I used my fitness pal app/website on my smartphone to track protein/fat/carbs ratio... After a month/6 weeks introduce carbs slowly on your exercise days... For me it meant eating 3 eggs every day, a lot of meat, handful of nuts, bit of dark chocolate and big bowl of steamed veg. Got used to it quickly, made me feel much better and I was never hungry!
