I used to weigh around 22stone, always had issues with my weight, went down to 12stone (Im 6'1) Never had any issue with either weight I was when it came to service I received. I lost 10stone, took me1 year, ate 3 meals a day, and did not do any exercise outside of my regular golf games on the weekends. Its really not about what you eat, I had a takeout every single friday. Though i was on between 700-1000 calories a day. At first its hard, but first week i lost 15lbs, second week 14, third week 9. After you see those sort of results, you really start to gain the motivation.
And there was no better feeling than after all of that work and effort, being able to go into a store and buying a pair of Armani jeans off the rack, and knowing when you go into stores, you will be able to find your size easily.
