Susan Reynolds, 29, hasn't eaten cooked food in seven years. She dines on noting but raw fruits, vegetables, nuts and seeds, the Daily Mail reports. Reynolds claims her diet is the reason for her good skin and youthful look.

She said her diet keeps her looking so young that she is often mistaken for a teenager. Even though her diet seems intense, Reynolds said she doesn't even crave cooked food and doesn't want to go back to her days as a college student where she ate mostly but fast food, junk food and drank alcohol.

To help switch up her limited diet Reynolds will have smoothies and has also created entire meals out of nothing but raw foods, for example she mastered a cold soup made from herbs, spinach and a lot of lettuce.

The 29-year-old businesswoman started with her raw food diet when she became interested in yoga at the age of 21 while on a six-month trip to India. Once returning home Reynolds decided to become a vegetarian and was training to be a yoga instructor.

"I went for something to eat in a café called Red Sugar in Edinburgh, which served raw food," she said. "The owners told me a bit about it so I went home, read up on it and decided to give it a go. The difference I felt in a day was incredible so I've done it ever since. I haven't had a hot meal in seven years."

"The benefits include mental clarity, positivity, health, energy, radiance and the ability to make choices," she said. "Other things people have commented on include smelling good, great skin and youthfulness. People say I look good for my age. I'm also emotionally balanced and happy."

She eventually started a business called Twist and Sprout, which offers advice to people who want to begin a raw food diet. She even convinced her parents and boyfriend, Louie, to try it.

She said her father probably won't stick to the raw food diet and her mother is used to unusual diets. She said her mother cured herself from ME 14 years ago by cutting all sugar from her diet.

"Mom used to be practically bed-ridden but she reversed it with the sugar-free diet," Reynolds said. "She doesn't have ME anymore. I think her experience was one of the things that inspire me."
