Weight loss resorts have grown increasingly popular as obesity rates rise in the US. Originally called "fat camps" in the late 1800s, the first modern weight loss resort opened in California in 1974. Now there are over 25 new resorts planned or under construction as the $60 billion weight loss industry continues to expand. Resorts pair weight loss programs with luxury amenities to help people lose weight in a relaxing environment. A week at a high-end resort can cost up to $14,500, while more affordable options start at around $1,000. As obesity remains a major health issue, the future of the weight loss resort industry looks promising.
