The findings contradict what has been observed in humans.
And a diet that includes a few days of caloric restriction each month reduces biomarkers of aging and disease in people, according to a small trial.

PIXABAY, MOJZAGREBINFOIn animal studies, bouts of fasting are shown to protect against aging-related diseases, suggesting that periodic fasting may benefit humans, too. But to cut out food for days at a time is no easy feat for most people, so researchers have designed a diet that mimics fasting without making dieters completely abstain from eating.
A short-term study of the diet in a small group of people published today (June 18) in Cell Metabolism yielded promising results. Biomarkers predictive of cancer, diabetes, and heart disease risk dropped among participants on the fasting diet, compared to those who maintained their normal eating habits.
“This single dietary change can counteract all these variables of aging, and I think that’s very impressive,” molecular biologist Christopher Hine of the Harvard School of Public Health told Science.
The researchers who conducted the study did not actually measure whether people’s health improved. Valter Longo of the University of Southern California who led the work told The Telegraph, “I think based on the markers for ageing and disease in humans it has the potential to add a number of years of life but more importantly to have a major impact on diabetes, cancer, heart disease and other age-related disease.”
The diet consists of five continuous days of caloric restriction each month. Participants ate prepared foods of vegetable soups, energy bars and drinks, tea, and a supplement amounting to 1,090 calories on day one and 725 calories for each of the other four days. “It’s not like eating ravioli, but it is better than going without,” Longo told Science. The rest of the month the volunteers could eat normally.
In mice, a similar regime did show health benefits—in particular, longer lifespan, less bone loss, and fewer cancers.
“This is arguably the first non-chronic pre-clinically and clinically tested anti-aging and healthspan-promoting intervention shown to work and to be very feasible as a doctor or dietitian-supervised intervention,” Longo said in a press release.
Longo said clinical trials are planned to test the intervention among larger numbers of people. One of the questions Naveed Sattar, a professor at the University of Glasgow, raised was whether people can stick to it. “The best way to alter weight trajectory or to lose weight is to make permanent and sustainable changes in one’s dietary composition,” Sattar, who was not involved in the work, told The Telegraph. “This way, folk can eat three meals a day and still have total less calorie intake than they had previously. This, for me, is better for mind and body, and critically, more sustainable.”

Periodic fasting may improve health but the problem is if you are planning to starve yourself to a diet, then it wouldnt help. I have tried it when i had to loose 11 pounds in a short duration.
Better then fasting, i just followed a diet recommended by lisa on her page, you can google for her by searching for "lisa plog diet plans" and you will find her.
I followed her from her weight loss journey and followed the same diet which she posted on her blog as her recommendation, shed off those 11 pounds within 4 weeks.
So, no fasting for loosing weight. Occassionally it is ok, but if you want to loose weight better get a proper diet like the lisa plog diet plans(google it).

The point of this study and article is not to look at fasting as a way to lose weight. In the article, the author quotes professor Sattar: "The best way to alter weight trajectory or to lose weight is to make permanent and sustainable changes in one’s dietary composition." If you take in less calories than you consume (caloric defecit), you will undoubtedly lose weight; no one can argue that.
I looked at the lisa plog diet; her page is full of grammatical errors and is very poorly written. After seeing her web page, it seems your post was solely to promote her (poorly-designed) website. If I'm wrong, I would love for you to reply and tell me how. In the meantime, pay a bit more attention to the articles you're posting on! Have a WONDERFUL day!
