Incredible Time-Lapse Video Shows a Man's 20kg Weight Loss Over 12 Weeks

The video shows Hobbs transforming from from 92kg to 72kg — a total loss of 20kg — over the course of 12 weeks. While the 55-second video makes the transformation go by in a mesmerizing blur, it certainly didn't come quickly or easily, Hobbs told MensHealth.com.

Hobbs explained that he had always been a pretty fit person, but after he graduated college two years ago and started a full-time desk job with an oil and gas company, his physical health took a back seat.

"I was at a point when I needed to get back in shape," Hobbs said. "I wondered, if I really committed for three months and went all out, what I could accomplish. I also have a passion for making videos, so I thought I could come up with something really cool."

Pictured above at 92kg, Hobbs was the heaviest he had ever been. Determined to make a change, starting January 1st, Hobbs took a shirtless photo a day and got to work.

Hobbs' Workout Plan

"I started off lifting heavy in the gym, doing sets of six to eight reps, going five to six times a week," he said. "After four or five weeks of that, I switched to higher reps, 10-12, and lower weights, but upped the intensity."

Hobbs added in cardio whenever he could, usually for 20-30 minutes after he was done lifting.

"I did a lot of incline on the treadmill, maxing out the incline and walking at about four miles per hour," he said. "If I didn't do the treadmill, I'd do the Stairmaster."

Hobbs' Eating Plan

Hobbs already had a background in working out, having been pretty consistent with it in college. The real challenge was changing his diet.

Through researching online and consulting a couple of friends, Hobbs got an idea of how many calories he should be eating and what types of foods would work best for him.

"My diet was pretty basic — oatmeal, chicken, eggs, spinach salads — and I stayed really consistent with it," he said. "I packed my lunch every single day."

Hobbs thinks his nutrition made the biggest difference in his results.

"The toughest part of this whole thing was people around me eating stuff I couldn't," he said. "Especially my roommate. One day, I got back from the gym and said, 'Man, I'm really craving a pizza,' and my roommate said, 'That's a great idea,' and ordered a large pizza and ate it in front of me."

Moving Forward

Now what's his plan? Relax a little bit, but not too much.

"I've gotten into a great routine both at the gym and with making my own meals, so I'm definitely going to stick to that," Hobbs said. "But I'm not going to feel bad if I go out and have a few drinks with my friends every once in a while or go out for a nice dinner."

Hey, everyone deserves a cheat meal now and then.
