These threads are a great motivational tool.
Roughly this time last year I was 15 stone, smoked 20-40 cigarettes a day and drank ~5 pints every night. I was a mess and looked and felt like crap. Had a word with myself ( ok I had a bit of a breakdown ) and now I’m 11 stone, no longer smoke and only drink a glass or two of wine a few times a week. It was tough going but my outlook has changed dramatically, I’m much happier and more confident now. I feel great.
No real trick to it either, just eat more intelligently and exercise. I eat a lot of oats ( just plain oats with sometimes raisins or chopped banana on them, my preference is for Scott’s old fashioned porage oats ), plenty of salmon and chicken, lots of salad and protein shakes when I train. Training consists of 3 or 4 gym sessions a week; squats and free weights, maybe some crunches.
Aim this year is to put on a stone of muscle.
Good luck on your journey all!
