Fifteen-year-old MacKenzie Walker of Windsor, Ontario, has dropped 100 pounds with hopes of someday becoming the next Ms. Olympia. 

Walker struggled with obesity and overeating as a child, weighing 170 pounds by the time she reached fifth grade. In middle school, she weighed over 220 pounds, and by high school she still weighed around the same amount.

In September 2013, she decided to make lifestyle changes that would allow her to reach a healthy weight.

Walker started changing her eating habits, doing light cardio, and following bodybuilders on Instagram for inspiration. She credits lifting weights and counting macronutrients for currently keeping the weight off.

Within six months, Walker lost 70 pounds, but the rapid weight loss caused her to have excess skin in her abdominal area.

Whats up guys! So as most of you know, my name is MacKenzie Walker. When I was 13 years old, I weighed 227 pounds at might highest weight. You live life with fear, you live life with a mental battle. You’re trapped inside your own body. You scream for help, but really, the only person who can get you out…is you. On September 24th 2013, I as a 13 year old girl, decided it was my last & final time to get my life on track. No more going to sleep in fear of not waking up, no more thinking about thing’s I can’t do because I’m overweight. I embarked on this journey & it was one that lead me somewhere I never would have guessed possible. A year and a half later, I am 100 pounds down from my highest weight of 227 pounds. Now at age 15, I am asking for something I am very uncomfortable asking for. Help. I suffer from a severe back pain daily, one that holds me back from focusing on school, one that holds me back from doing intense forms of cardio, one that makes it difficult to make it up the stairs with ease. I experience uncomfortable temperatures under my stomach hang, that cause me to sweat when I shouldn’t be. At 15 years old, no teenager should ever have to go through the pain I do daily. The mental struggle I face now, is much worse than it was 100 pounds ago. On September 21st 2015, I will be going in for a consultation. I have been quoted roughly $8900 which will include my hospital fee’s, the surgery & the consultation rate. I am not one to ask for help, but in this case… I must. Please, if you wouldn’t mind donating even just a dollar to my surgery fund, you’d be contributing to changing my life. & for that, I can not thank you enough for.

She was told that she would need abdominoplasty, or a “tummy tuck,” to remove the extra skin.

Walker set up a GoFundMe page to pay for the $9,000 procedure. Her fitness coach, Chris “Beastmode” Jones, reached out to his YouTube followers to seek donations for her surgery. She was able to come up with the necessary funds in two months.

The surgery was performed on July 28, 2015, and Walker is still recovering. 

However, that has not stopped her from returning to the gym, where she is continuing her physical transformation.
