Contestants were encouraged to take drugs and other extreme measures
The Biggest Loser is an American competition reality TV show that initially ran on NBC for 17 seasons from 2004 to 2016. The show features obese or overweight contestants competing to win a cash prize by losing the highest percentage of weight relative to their initial weight. The show has been criticised for its encouragement of extreme weight loss methods, with several former contestants claiming they were encouraged to take drugs and other extreme measures to lose weight.
In 2016, several former contestants spoke out about the extreme measures they were encouraged to take to lose weight. According to the New York Post, contestants were told to take Adderall and pills called "yellow jackets," which contain ephedra, a weight-loss drug that has been banned by the FDA. These allegations sparked an internal NBC investigation. Contestants also reported taking amphetamines, water pills, and diuretics, as well as severely restricting their food intake and vomiting after meals. One contestant reported vomiting every day and being encouraged by a trainer to vomit to "lose more calories."
The weight-loss regimen promoted by the show involves severe caloric restriction combined with up to six hours a day of strenuous exercise. This type of regimen carries risks, including a weakening of the heart muscle, irregular heartbeat, and dangerous reductions in potassium and electrolytes. Contestants are required to certify that they believe they are in excellent physical, emotional, and psychological health, but the show has been criticised for its lack of attention to contestants' health. In 2014, the Season 15 winner, Rachel Frederickson, weighed in at an emaciated 105 pounds, prompting one of the trainers, Michaels, to quit, as she was "deeply concerned" about the contestants' health.
The show's focus on competitive weight loss and extreme methods has been criticised by health experts as counterproductive and dangerous. Contestants on the show lose upwards of 10 pounds per week, far exceeding established medical guidelines for safe weight loss of 1-2 pounds per week. A 2016 study in the journal Obesity followed 14 contestants during and after one season of the show, finding that drastic weight loss was associated with a slow metabolism and low levels of hormones that affect hunger. Additionally, the show has been criticised for its portrayal of obesity as a form of mental weakness and its potential to spread weight loss stereotypes and misinformation.

Contestants were told to take Adderall and pills containing ephedra
The Biggest Loser is an American competition reality TV show that initially ran on NBC for 17 seasons from 2004 to 2016. The show features obese or overweight contestants competing to win a cash prize by losing the highest percentage of weight relative to their initial weight. The show has been under fire for years for its encouragement of extreme weight loss methods. Contestants say they were told to take Adderall to speed up their weight loss, as well as pills called "yellow jackets," which contain ephedra—a weight-loss drug that has been banned by the FDA since 2004. Ephedra is a stimulant herb usually derived from the stem and branches of Ephedra sinica. It stimulates the heart, lungs, and nervous system. While it has been shown to aid in short-term weight loss, it is linked to severe side effects such as high blood pressure, heart attacks, seizures, strokes, irregular heartbeat, and even death.
According to Joelle Gwynn, a contestant on the show in 2008, Harper and his assistant handed out Adderall and yellow jackets, and told her, "Take this drug, it'll really help you." Another contestant, Suzanne Mendonca, claimed that Dr. Huizenga told her to fight dehydration with tablespoons of baking soda. Dr. Huizenga has denied these reports, saying they are hurting him professionally as a medical expert.
The weight-loss regimen on the show involves severe caloric restriction combined with up to six hours a day of strenuous exercise, which can pose risks such as a weakening of the heart muscle, irregular heartbeat, and dangerous reductions in potassium and electrolytes. Contestants are required to certify that they believe they are in excellent physical, emotional, psychological, and mental health before participating. Despite this, several contestants have ended up in the hospital due to their extreme weight loss methods. Physicians and nutritionists have expressed concern that the show's focus on competitive weight loss is counterproductive and dangerous.
The show's format contributes to the encouragement of extreme measures. Each season starts with a weigh-in to determine the contestants' starting weights, which sets the baseline for determining the winner. The contestants are then grouped into teams, each working with a specific trainer or all trainers. The trainers design comprehensive workout and nutrition plans for the contestants. During team-based competitions, the team that loses the highest percentage wins, and the losing team must send someone home. When the teams dissolve and the show becomes an individual competition, the two contestants with the lowest percentage of weight loss are eligible for elimination. The eliminated contestants compete for a smaller prize, while those remaining compete for a larger prize and the title of "The Biggest Loser."

Contestants took amphetamines, water pills, diuretics, and threw up
The Biggest Loser is an American competition reality TV show that initially ran on NBC for 17 seasons from 2004 to 2016. The show features obese or overweight contestants competing to win a cash prize by losing the highest percentage of weight relative to their initial weight. The show has been under fire for years due to several former contestants claiming they were encouraged to take drugs and other extreme measures to lose weight.
According to Suzanne Mendonca, a contestant from Season 2, contestants took amphetamines, water pills, and diuretics, and threw up in the bathroom. She also claimed that her trainer, Bob Harper, encouraged her to vomit, stating that she would "lose more calories." Mendonca further expressed that the show ruins lives mentally, emotionally, and financially. Joelle Gwynn, another contestant, supported Mendonca's claims, stating that Harper told her to severely restrict her food intake and lie about how much she was eating.
In addition to amphetamines, water pills, and diuretics, contestants were also told to take Adderall and "yellow jackets" to speed up their weight loss. "Yellow jackets" contain ephedra, a weight-loss drug that has been banned by the FDA. These allegations were made against Bob Harper and his assistant, who denied the claims. However, several contestants have consistently reported that the show encouraged drug use and extreme measures for weight loss, which resulted in severe health consequences and significant weight gain after the show.
The weight-loss regimen on the show involves severe caloric restriction combined with up to six hours a day of strenuous exercise, which carries risks such as a weakening of the heart muscle, irregular heartbeat, and dangerous reductions in potassium and electrolytes. Contestants are required to certify that they believe they are in excellent physical, emotional, psychological, and mental health, despite the potential dangers of the program. The extreme methods promoted by the show have been criticized by weight-loss experts as being counterproductive and dangerous, with some suggesting that the dietary guidelines and workout routines are flawed.

Contestants experienced drastic weight loss, losing an average of more than 100 pounds each. The show has been criticised for promoting an unhealthy approach to weight loss. Contestants were reportedly encouraged to take drugs and other extreme measures to lose weight.

Contestants also reported engaging in other unhealthy practices such as severe calorie restriction, purging, and excessive exercise.

Contestants were required to certify that they believed they were in excellent physical, emotional, psychological, and mental health, but several former contestants have since regained some or all of the weight lost, and some have spoken out about the physical and mental toll of their experiences on the show.

Contestants are required to certify that they believe they are in "excellent physical, emotional, psychological, and mental health."

The Biggest Loser did not return to NBC after 2016 but was picked up by USA Network in 2020. Despite some changes, critics argue that the show remains fundamentally toxic, promoting workout culture and perpetuating stereotypes about obesity and weight loss.
