  • Two Beijing-based wellness consultants tried, with mixed results – Christian François lost 9kg in three months; Alessia Chizzoniti quit because of health issues

To lose weight, Christian François started fasting two years ago. Eating two meals a day between noon and 9pm, he lost 9kg (19.8 pounds) in the space of three months.

“I increased my exercise during those three months,” the Beijing, China-based wellness and nutrition consultant recalls. “I was working out for one hour, five times a week, in the first month, and doubling the hours in the second and third month. I was burning myself out.”

The first week was the hardest, he says, as he would wake up at 8am and could not eat until midday. “As I increased my workouts, I was moody and cranky as I was hungry. But the body got used to it quickly.”

Once he reached his goal weight, the 26-year-old switched to a far less restrictive way of fasting. “I attained the discipline of understanding that I don’t always need food. I stopped daily fasting – now, I skip meals throughout the day whenever I go out for dinner at night so that I can enjoy the food more.”

Various studies have shown that fasting improves health both in people and animals. One recent study, from the University of Wisconsin in the US, showed that eating less often does more to improve the health and lifespan of rodents than simply eating less.
