Somebody sent them to me, and I reposted one of their storiesjust to see what people would say.

I ended up getting messaged by former employees and a bunch of people.

Since then, Gellis says shes received about a thousand messages a daymany of them anonymousall about F-Factor.

Its clear people are paying attention to this controversybut to what end?

(The diet does not explicitly require followers to track or limit their calories.

F-Factor asks followers to eat35-plus grams of the nutrient per day(thats 10 grams more than theU.S.

Department of Agricultures 25-gram recommendation for women).

People can also work directly with F-Factor dietitians withone-on-one nutrition counseling and group sessions.

Some people have reportedly paid as much as $20,000 for these services, according to theNew York Times.

However, that is apparently not the experience of everyone who has tried the eating plan.

Is there anyone else [whos] gotten major canker sores and mouth sores?

asked one of Gelliss followers about the diet.

People also shared pictures of rashes, hives, and swollen tongues they attribute to the diet.

One commenter anonymously wrote, During quarantine, I ordered the powder and made so many recipes.

I developed a horrible rash under my armpits and had a virtual dermatologist appointment.

I was on three different steroids and nothing worked.

The symptoms that allegedly come along with the diet arent strictly physical.

Several have lost their period or experienced their hair falling out.

F-Factor has always been committed to transparency, Zuckerbrot writes in her emailed statement.

However, Zuckerbrot doesnt offer many specifics about the companys protocol for investigating claims.

Food has no moral code.

Zuckerbrot denies the assertion that her diet plan is restrictive.

She reiterates that the diet is aimed at good health, not just fat loss.

However, as Zeitlin outlines, limiting calories is not the only thing that defines a restrictive diet.

A good amount of fiber is, honestly, 25, maybe even 30 grams a day.

Anything over that can beexcessive fiber.

Too much fiber can lead to all types of GI distress, including bloating, constipation, or diarrhea.

How can we expect women to make peace with their bodies when theyre constantly being fed conflicting information?
