Like so many of us, Hunter Hobbs of Norman, Oklahoma, made a deal with himself to get serious about his health and fitness for a 12-week period. He was curious to see what kind of results he could achieve in just three months, so he took a photo of himself every day during his transformation which began in January.

He stitched the photos together to create an unbelievable time-lapse video that will have you wanting to make a similar body transformation commitment. In only 12 weeks, Hobbs lost an impressive 42 lbs, going from an initial weight of 202 lbs to 160 lbs.

Hobbs claims he worked out consistently five to six days a week, using a combination of weightlifting and cardio to achieve his results. However, he also revealed that it was his diet and not the workouts that was the hardest part of the challenge.

He says he ate only “chicken, sweet potatoes, oatmeal, salads, almonds, whey protein shakes, etc.” Hobbs also told the Daily Mail, “I also cooked all of my meals, brought my lunch to work every day and rarely ate out.”

“I initially tracked all that I was eating to get a better idea of how many calories, protein, carbs and fats I was taking in and then just stuck to the same stuff so I knew what I was eating,” Hobbs added. He also revealed that he gave up alcohol and soda completely and drank at least a gallon of water a day.

Hobbs says all the hard work was definitely worth it, but now that he’s completed his 12-week challenge, he plans to relax a little bit and enjoy life rather than deprive himself of the little indulgences he loves all of the time.
