The 500-calorie diet is not suitable for everyone and should only be undertaken under strict medical supervision. While it may lead to rapid weight loss, it also carries risks such as malnutrition and micronutrient deficiencies.
Fastest ways to lose weight usually combine:
“Everyone's body is different, but for most people, eating less than 1,200 calories a day could slow your metabolism enough to make it harder to lose weight,” says Uy. Some signs you have low metabolism include: Weight loss progress that has slowed down. You feel tired or low energy throughout the day.
Consuming at least 1,200 calories per day has often been touted as the minimum for basic bodily functions and to stay out of starvation mode, but the amount is actually too low. A healthy amount of calories for adult women ranges from 1,800 to 2,400 calories per day and for men it's 2,000 to 3,200 calories per day.
As a general rule though, most nutrition experts recommend never going below 1,000-1,200 calories a day if you're dieting on your own. It's also worth bearing in mind that the body doesn't suddenly 'enter' and 'leave' starvation mode, like crossing the border from Devon into Cornwall.
Though it differs depending on age and activity level, adult males generally require 2,000-3000 calories per day to maintain weight while adult females need around 1,600-2,400 according to the U.S Department of Health. The body does not require many calories to simply survive.

Another intermittent fasting plan, known as the 5:2 approach, involves eating regularly five days a week. For the other two days, you limit yourself to one 500–600 calorie meal. An example would be if you chose to eat normally on every day of the week except Mondays and Thursdays, which would be your one-meal days.

One of the best ways to lose body fat is through steady aerobic exercise, such as brisk walking. Work up to at least 30 minutes of aerobic exercise most days of the week.
