Joe Weider

The family founded Weider Nutrition in 1936, considered the first sports nutrition company. Now called Schiff Nutrition International, they were the creators of Tiger's Milk nutrition bars and related products, one of the earliest lines of sports foods.[7] There are now two companies making supplements and bearing Weider's name - Weider Global Nutrition, and Weider Germany GmbH that is popular in Europe.

In 1953, Your Physique was renamed Muscle Builder magazine. The name changed again to Muscle & Fitness in 1980. Other magazines published by Weider's publishing empire included Mr. America, Muscle Power, Shape magazine, Fit Pregnancy, Men's Fitness, Living Fit, Prime Health and Fitness, Cooks, Senior Golfer, and Flex, in addition to the "skin magazines" Jem Magazine and Monsieur. The last two publications caused at least two clashes with obscenity laws. Weider has written numerous books, including The Weider System of Bodybuilding (1981), and co-wrote the 2006 biography Brothers Of Iron with Ben Weider. In 1983, Weider was named "Publisher of the Year" by The Periodical and Book Association. In 2003, his publication company, Weider Publications, was sold to American Media.

In 1972, Weider and his brother Ben found themselves the target of an investigation led by U.S. Postal inspectors. The investigation involved the claims regarding their nutritional supplement Weider Formula No. 7. The product was a weight-gainer that featured a young Arnold Schwarzenegger on the label. The actual claim centered on consumers being able to "gain a pound per day" in mass. Following an appeal wherein Schwarzenegger testified, Weider was forced to alter his marketing and claims.[8][9] Also in 1972, Weider encountered legal problems for claims made in his booklet Be a Destructive Self-Defense Fighter in Just 12 Short Lessons.[10]

Weider was ordered to offer a refund to 100,000 customers of a "five-minute body shaper" that was claimed to offer significant weight loss after just minutes a day of use. The claims, along with misleading "before and after" photographs, were deemed false advertising by a Superior Court Judge in 1976.[11]

In the 1980s, Weider found himself answering charges levied by the Federal Trade Commission (FTC). In 1984, the FTC charged that ads for Weider's Anabolic Mega-Pak (containing amino acids, minerals, vitamins, and herbs) and Dynamic Life Essence (an amino acid product) had been misleading. The FTC complaint was settled in 1985 when Weider and his company agreed not to falsely claim that the products could help build muscles or be effective substitutes for anabolic steroids. They also agreed to pay a minimum of $400,000 in refunds or, if refunds did not reach this figure, to fund research on the relationship of nutrition to muscle development.[11]

In 2000, Weider Nutritional International settled another FTC complaint involving false claims made for alleged weight loss products. The settlement agreement called for $400,000 to be paid to the FTC and for a ban on making any unsubstantiated claims for any food, drug, dietary supplement, or program.[12]

Weider died of heart failure on March 23, 2013, at Cedars-Sinai Medical Center in Los Angeles, at the age of 93.[13][14]
