In a video that has been viewed more than 4.8 million times, Emma refers to herself as practicing a body cleansing method. The woman, who claims to be a doctoral student and holistic nutrition coach, only drinks water and electrolyte drinks.

According to the 25-year-old woman, the intense hunger only lasted for the first and second day. She momentarily felt weak and considered breaking her fast, but then she determined to continue her diet. "I constantly remind myself of the benefits I can feel the longer I fast," said Emma Roberts. "I distract myself from the hunger by keeping busy with work, calling friends or family, and watching television."

Although not mentioning how much weight is reduced, Emma revealed the great benefits of this water fasting. Emma Roberts admitted that her skin became cleaner, her concentration increased, and her body fat decreased.

Because of the great benefits of the diet, Emma intends to do it at least twice a year. Unfortunately, a diet of only drinking water without eating at all is considered unhealthy. Certified diet expert, Wendy Lord, said that drinking only water for five days can pose risks. If done without professional supervision, it can cause dehydration, lack of nutrition, and other health problems.
