The Advocare cleanse phase can cause severe diarrhea that may lead to dangerous electrolyte imbalances, according to the National Institute for Fitness and Sport. Some individuals have experienced serious health problems after using Advocare products, such as severe gastric pain, high blood pressure and organ failure.
The meal plans in the Max phase are deficient in key nutrients and long-term use may result in malnutrition, says the National Institute for Fitness and Sport. The stimulants in the energy drinks have not been approved for use by the Food and Drug Administration and may not be safe.
The Advocare weight loss program consists of a "cleanse" phase followed by a "Max" phase. Energy drinks, supplements and meal replacement drinks are key components of the plan, according to the National Institute for Fitness and Sport.
