Luis Miguel's long-awaited return to the stage has been confirmed. The legendary Puerto Rican-Mexican singer has announced his new live performances for 2023.

But beyond the announcement of his comeback, the singer took many by surprise with his weight loss. According to reports, the Mexican singer underwent a strict diet that allowed him to get back in shape.

Intermittent fasting

Rumours sparked about a potential health issue until it was reported that the musician managed to lose more than 20 kilos after following the intermittent fasting method - a controversial technique among nutritionists, because many of them are in favor of it, but others consider it very dangerous.

"People don't know to what extent obesity is a disease," Luis Miguel said according to Spanish TV show El Hormiguero.

"It's unsettling to give that information and people don't know. I did 36-hour intermittent fasts; this worked for me but it is not recommended for everyone."

Intermittent fasting is a type of eating pattern where a person alternates between periods of eating and fasting. It involves restricting food intake for a certain period, usually between 12-24 hours, followed by a period of normal eating. It has become a popular method for weight loss and maintaining good health.
