It is meant to help people live longer, healthier lives.
The longevity diet recommends following a plant-based diet that includes little-to-no meat and poultry and periodic fasting.
More research is needed before this diet can be recommended as a way to increase your lifespan.

The guidelines include following a five-dayfasting-mimicking dietperiodically throughout the year.
Older adults may eat slightly more than that, including animal protein, to help preserve muscle mass.
The longevity diet recommends avoiding dairy products.
The guidelines also suggest not eating during the three to four hours before bedtime.
This involves consuming limited amounts of foods, mainly vegetables, nuts, and seeds, for five days.
Dr. Longo has also researched the benefits of fasting-mimicking diets.
Can the Longevity Diet Help With Weight Loss?
Any diet that includes mostly vegetables, fruits, and whole grains is likely to help you lose weight.
This is true of the longevity diet as well as other plant-based diets.
There has also been very little research done into the effects of diet on human longevity in general.
Many studies have found that it may be enough to simply choose lean meat and low-fat dairy products.
Fasting-Mimicking
It is also unclear whether a fasting-mimicking diet can help increase longevity.
The goal of the diet is to help you live longer.
People following the longevity diet should eat plenty of fruits, vegetables, and whole grains.
The research into whether or not this diet can help you live longer is limited.
Always discuss any new diet with your healthcare provider before deciding if it’s right for you.
