January is the most popular time of the year for people to make an effort to get into shape, but you don't need to wait for the new year to roll around to start making a major change in your life.

LaKeisha Shurn from Berkeley, CA spent the last 100 days going to the gym and documenting her weight loss journey, and her results show not just a healthier person, but a happier one.

In her first video, LaKeisha reveals that she's at 348 pounds and suffers from low self-esteem and depression. "I always just thought of myself as someone who was unattractive and was not fit to be married or have kids," she says in her video diary.

LaKeisha vows to go to the gym for 100 days, and she does just that. We see footage of her running on the treadmill, working the machines and taking group exercise classes at 24 Hour Fitness.

By Day 52, she looks noticeably happier. By Day 70, she reaches one of her first goals - dropping out of the "300 Club" and hitting 299 pounds. By Day 90, her body had become much more flexible, and she could pull her leg up straight.

By the end of LaKeisha's 100 Days, she dropped from a size 26 to a size 22 and found the self-esteem that had been missing in her life.

"I want you to see how one person really changes everything about their life," she says.

LaKeisha's 100-day program was inspired by Give It 100, the online community curated by Karen Cheng. Last year, Karen recorded her progress as she taught herself how to dance in 100 Days, and soon after started Give It 100 to inspire others to accomplish their goal, be it learning to dance, lose weight, or any sort of project that takes patience and dedication to complete.

"The video has totally changed the trajectory of my life," Cheng told us back in November. "Now, I'm doing something that could actually make a difference." You can follow LaKeisha's day-by-day progress and all sorts of other journeys at Give It 100.
