The 26-year-old joiner would easily consume 6,000 calories in a day, while eating nothing but fast food and his weight shot up to 17st.He knew things had to change when he went on holiday to Majorca and was too embarrassed to take off his top when he went swimming. To make matters worse, his girlfriend Rachel Brown, 30, was a gym instructor with a toned physique.Dan, from Grimsby, knew that the only way to match Rachel's figure was by completely transforming his life.He gave up his alcohol binges and went from being overweight to a body builder in just over a year.The father-of-two said: 'I still cannot believe how I have changed. 'The key for me was giving up the booze, if I was on the lash, I would be eating all of the wrong things and bingeing on fast food. 'I could easily get through 6,000 calories in a day and would drink a bottle of vodka over a weekend. 'I was still going to the gym during this time but it was making no difference to my body shape. 'I had man boobs and hated the way I looked. 'The low point for me was when a lass pointed at me and said I was, 'the fat one.'' That was the trigger which prompted Dan to get serious about fitness.He changed his diet - swapping his favourite Coco Pops and takeaways for a high protein diet of grilled chicken and fish.(dailymail.co.uk)Bakudaily.Az
