Nice job man! Lot of people get motivated and start their physical training which last maybe a week or two then they just give up. The hard part is to maintain that routine and stick with it. You did an awesome job! I was in the same boat. My weight was 190lbs 20% body fat. Took me a year to get to 145lbs and now i weight 168 lbs with 6% body fat. The only thing i can suggest for you is that replace the casein in the day with either some salmon or chicken, you can also do whey. Do casein before bed. Other then that you are on the right track brother! Keep it up!
