David protein bar founder pushes back after lawsuit alleges company undercounted calories

A growing controversy surrounding David protein bars — a viral favorite among wellness influencers — is drawing comparisons to the movie "Mean Girls."

NBC Universal

A class action lawsuit filed in January alleges that the popular bars have more than 400% more fat and 80% more calories than advertised. It has prompted a flurry of recentsocial media postsreferring to the film's queen-bee character Regina George, who finds out that the "healthy" diet bars she was given are actually making her gain weight, not lose it. Others likened the situation to the "Seinfeld" episode in which the "nonfat" yogurt that everyone's obsessed with is — spoiler alert — full of fat.

On Wednesday, the company's founder, Peter Rahal, responded in astatement on X: "No one is getting Regina Georged."

In an interview, Rahal said the issue comes down to the way calories are calculated.

"It's a frivolous case where they're using the wrong measurement and method to measure calories," he said.

The labels on David protein bars — which come in flavors like fudge brownie, blueberry pie and cake batter — list 150 calories and 2 grams of fat. But the lawsuit describes independent tests that found the bars to have 268 to 275 calories per serving and 11 to 13.5 grams of fat.

The plaintiffs say the discrepancy violates Food and Drug Administration standards, which mandate that the nutrient content of a food item not exceed the declared value by more than 20%.

But Rahal said the plaintiffs' testing was flawed. The discrepancy, he said, has to do with an ingredient in David protein bars called esterified propoxylated glycerol, or EPG, a modified plant-based fat substitute that moves through the body without getting digested.

"This is what makes David have 150 calories," Rahal said. "It's really a special ingredient that allows the food to taste like fat but doesn't have the caloric impact."

The laboratory cited in the lawsuit, Rahal said, used a device called a bomb calorimeter to calculate the calories in David bars. That method includes the calories in nondigestible ingredients — including EPG — in its count, he added.

"The science is unequivocal. You don't use a bomb calorimeter to measure nonnutritive things. It's very, very basic," Rahal said.

The calorie count listed on David protein bars, Rahal added, is based on a calculation of just the calories the body absorbs. The company complied with FDA regulations when it developed its bars, he said.

The lawsuit does not specify the method used to measure the calories. Anresco Laboratories, which did the testing, said it could not comment because of confidentiality agreements.

Amy Goodson, a registered dietitian, said EPG has been around as an ingredient since the 1980s and has gone mainstream in recent years.

"This ingredient allows you to actually put less fat grams on the food label itself, because it yields 92% less calories than a typical gram of fat would," she said. "It's resistant to digestive enzymes, so it's going through your system, but it's not actually digesting."

That's a confusing concept for the everyday consumer, Goodson added.

"We look at a nutrition facts label and assume that what's on the label is what's in the product," she said.

David Protein, founded in 2024, quickly rose to prominence, with top names in the wellness and longevity space signing on as investors, including Andrew Huberman, a neuroscientist and podcaster, and Peter Attia, a celebrity doctor and author. Last month, Attia stepped down as chief science officer at David Proteinamid backlash over his emails with Jeffrey Epstein.

The hype around David bars has come amid a national obsession with protein. Thenew U.S. dietary guidelines, unveiled in January, place aheavy emphasis on protein, recommending it at every meal. Brands have capitalized on the craze: "Doritos Protein" chips hit store shelves this month, Starbucks is selling protein matcha, and the company Protein Pints even advertises high-protein ice cream.

Rahal said David Protein plans to fight the lawsuit.

"Any time you're on the forefront of innovation, there's confusion," he said. "We stand by our product fully."

'No funds for food.' TSA agents sleeping in cars as shutdown continues.

As thepartial government shutdowncontinues and Transportation Security Administration officers work without pay, many are struggling to stay afloat financially.

USA TODAY

The partial shutdown began in mid-February after Congress failed to pass funding for the Department of Homeland Security, which oversees TSA.Roughly 50,000 TSA officersare continuing to work but without regular pay during the funding lapse, raising concerns about staffing shortages and absenteeism asspring break travelramps up.

"Numerous employees have reported to me that their bank accounts are at zero or negative," Johnny Jones, Secretary-Treasurer of AFGE TSA Council 100 and a Dallas-based TSA worker, told USA TODAY. "No funds for daycare, no funds for food. They just want to know why the hell they can't get paid when we have money toshoot missilesinto other countries."

Friday, March 13, will be the first time TSA workers miss their full paychecks.

As TSA officers work to find ways to bridge their own financial gaps, Jones acknowledged that airport security lines havegotten longer.

"There is a significant part of the workforce that is working other duties outside of their duties at TSA," he said. "I hope they're not panhandling at the airport. There are people who are staying at the airport, not leaving, they're sleeping in their car to conserve gas, consolidating their work life."

Fewer agents are showing up to work as a result, with White House Press Secretary Karoline Leavitt saying in a March 11social media postthat "300 (TSA) officers quit," citingCBS News reporting. The rates of officers calling out have more than doubled since the shutdown began, the same CBS report found, with some airports facing the absence of more than 50% of their frontline TSA workforce on some days.

"Today, travelers are facing TSA lines of up to nearly 3 hours long at some major airports, causing missed flights and massive delays during peak travel," TSApreviously told USA TODAY in a statement. "These frontline heroes received only partial paychecks earlier this month and now face their first full missed paycheck, leading to financial hardship, absences, and crippling staffing shortages."

Some airports, like Denver International Airport (DEN), have even taken up collections to help TSA employees with some basic assistance.

"Once again, DEN's federal employees are working tirelessly to ensure our airport operates efficiently and safely without getting paid. TSA employees just missed their first paycheck, and as we enter a busy Spring Break travel period, we want to do what we can to ease the stress of this moment," DEN CEO Phil Washington said in astatement. "That's why we are calling on the public, our passengers, and other airport employees to donate grocery store and gas gift cards to help make this moment a little more bearable for these federal workers."

The collection is meant to help TSA officers purchase necessities while they're not getting paid.

"Donated gift cards can be from stores like King Soopers, Safeway, Walmart, Costco, and Target. Ideal gift cards include those stores that sell both gas and food. Denominations should be in $10 or $20 gift cards only. Visa gift cards cannot be accepted," thedescription of the eventsays.

Jones said other airports are doing similar charity drives, but added that it can be harder to get and distribute assistance at larger airports. He noted that some TSA employees have lost their housing when they were unable to pay rent on month-to-month leases as a result of the funding lapse.

"We took the oath to uphold the Constitution and protect the public, but the people who are elected to Congress took the same oath, but they don't do their job and fund the government," Jones said. "We are caught in partisan politics."

Do TSA PreChek, Global Entry still work?

Despite the disruption, DHS and TSA say expedited screening programs remain available.TSA PreCheck is still operational, allowing enrolled travelers to move through dedicated lanes and typically avoid removing belts and light jackets during screening. The agency reversed an earlier plan to suspend the program after pressure from airlines and lawmakers concerned about further slowing airport checkpoints, although officials warned that TSA PreCheck lanes could be closed on a case-by-case basis based on staffing during the shutdown.

DHS announced Global Entry lines would reopen on March 11, saying the change was meant toalleviate disruptionsfor travelers amid the shutdown.

How can I check the TSA line wait times at my airport?

Travelers worried about long security lines cancheck real-time wait estimatesbefore heading to the airport.

TSA publishes historical andlive checkpoint wait-timeinformation on its MyTSA mobile app and on the agency's website, where travelers can search by airport and time of day.

Travelers should be aware that some information on theTSA website isn't being updatedbecause of the ongoing government shutdown, the agency said in a statement on Feb. 17. Banners on both the TSA and U.S. Customs and Border Protection websites warn that, "Due to the lapse in federal funding, this website will not be actively managed."

That's different fromthe last government shutdownthat ran from October to November 2025, when TSA security wait times continued to update as usual.

This time, TSA confirmed to USA TODAY via email that both theMyTSA mobile appand the agency's wait‑time tracker are down because of a partial U.S. government shutdown now in its fourth week.

The app is also supposed to show whether TSA PreCheck lanes are open. However, some airports also publish their own checkpoint wait times on official airport websites or social media feeds. Checking those before leaving for the airport can help travelers decide whether they need to arrive earlier than usual.

How did Miami Ohio loss alter bracket?

With the loss, Miami (Ohio) joins the bubble picture and essentially pushes teams down the bracket. The MAC champion becomes a bid stealer since it would be a two-bid league instead of one, and teams could see their fate altered because of it.

An example is Auburn going down to the first four out after it was slated in the field, and San Diego State going from first four out to next four out.
