Why did Colter Barnes leave Alone?

Colter Barnes was one of the participants in the eighth season of Alone, however, he was medically evacuated after 67 days for losing too much weight.

Alone is an American reality television series on the History Channel. It features the self-documented daily struggles of 10 individuals. The individuals should survive in the wilderness for as long as possible, with a limited amount of survival equipment. With the exception of medical check-ups, the participants are isolated from each other and other humans. However, they may “tap out” at any time, or be removed due to failing a medical check-in. The contestant who remains the longest wins a grand prize of $500,000.

The seasons have been filmed across a range of remote locations. It is usually on indigenous-controlled land, including northern Vancouver Island, Nahuel Huapi National Park, Great Slave Lake, Chilko Lake, and British Columbia. Colter Barnes was one of the contestants on Alone season eight. He was born in Montana but was raised in Oregon. Colter has spent the last 14 years living, working and homesteading in the Alaskan bush, far from the road system.

Even though Colter grew up hunting and fishing with his friends and family, it was not until he moved into the fly-in only village of Kokhanok that he understood what living off land meant. Under the guidance of the local residents, he began the physically, mentally, emotionally and spiritually challenging and rewarding pursuit of a more subsistence-based lifestyle.

Barnes hoped to combine modern homesteading science and skills, with indigenous wisdom and traditions to win the eighth season of Alone. He also wished to demonstrate the beauty, meaning and fun that can be found when people slow down and simplify life.

Colter selected the following items to bring on his survival journey to Grizzly Mountain: sleeping bag, pot, axe, saw and tarp. Additionally, he also brought a bow and arrows, snare wire, multitool, paracord and a fishing line with hooks.

Unfortunately, Barnes was removed from the show due to failing a medical check-in. However, he managed to last 67 days in the wilderness. He was evacuated due to a low body mass index (BMI), and he had also lost too much weight.
