Weight Lost Survivor 

The record for the most weight lost on Survivor is held by a contestant named Richard Hatch, who lost a total of 103 pounds during his time on the show. Hatch was a contestant on the very first season of Survivor, which aired in 2000, and he was a member of the Tagi tribe.

Hatch's weight loss journey on Survivor was quite impressive, as he started the game at a weight of 240 pounds and finished at a weight of 137 pounds. He lost the majority of his weight during the first few weeks of the game, when he was struggling to find food and was forced to survive on a diet of mostly rice and fruit.

Despite his significant weight loss, Hatch was still able to perform well in the physical challenges and was a strong competitor throughout the game. He ultimately won the title of Sole Survivor and took home the $1 million prize.

It's worth noting that while Hatch's weight loss on Survivor was certainly impressive, it's important to remember that weight loss on the show is often accelerated by the extreme conditions and physical demands of the game. Contestants are often forced to survive on limited rations and engage in strenuous physical activity, which can lead to rapid weight loss. It's also worth noting that weight loss of this magnitude is not always healthy or sustainable, and it's important to approach weight loss in a healthy and responsible way.
