Is Everything We Learned About Fat Wrong?

Fat Fiction Director Jennifer Isenhart Discusses Film With Dr. Brian Lenzkes in LowCarbMD Podcast Episode 95

What if the “low fat, heart healthy” diet represents one of the most damaging public health recommendations in the history of our country?

That is the question director Jennifer Isenhart set out to answer with her new film, Fat Fiction, which premiered in Los Angeles last Friday, had a spectacular screening at the Low Carb Denver Conference last Saturday, and is now available for online watch party screenings through the innovative FanForce TV app. Sign up here to enjoy a virtual cinema screening from the comfort of your own home.

UPDATE, March 22: It was announced Sunday that Fat Fiction is now available for streaming on Amazon. Rent or buy here.

Dr. Brian Lenzkes, co-host of the popular LowCarbMD podcast, interviewed Isenhart for Episode 95. The two discussed a wide array of low carb topics, including the making of the film, the decades of faulty diet advice we’ve all received insisting that saturated fats are bad for us, and what we can do to reclaim our health. Fat Fiction features a long list of low-carb experts, including Lenzkes, and highlights several of Lenzkes’ patient success stories.

UPDATE: In the interview, Jennifer discusses how fans can sign up to host a screening of Fat Fiction at a theater in their community. This option has been delayed until after June 1 (at the earliest) by the Covid-19 virus, but online screenings are available, with Q&As being set up with one or more of the experts featured in the film.

Fat Fiction Director Jennifer Isenhart was the featured guest on Episode 95 of LowCarbMD co-host Brian Lenzkes.

“A lot of us in the low-carb community understand this stuff pretty well,” said Isenhart, “but I really wanted to lay it out in a way that somebody who hadn’t been exposed to this information before could understand it.”

“Fat Fiction” addresses the sad truth that 1 in 2 Americans — half of our population — has either diabetes or pre-diabetes and many of them don’t even know it. Isenhart’s film assembles some of the best known low-carb experts who, collectively make the case that our nation’s own Dietary Guidelines contributed to our epidemic of metabolic disease and obesity.

“It’s not calories in, calories out,” Isenhart said. “It’s the insulin model of weight gain, how carbohydrates affect your blood sugar, and why it makes such a negative impact on our bodies when we eat sugar.”


“Do calories matter?” Lenzkes asked rhetorically. “Yes, but satiety matters even more. If you’re not hungry all the time, you’re not going to be eating all day.”

In the film, Isenhart followed the results of three individuals who followed a low-carb diet for one week, and then switched to a low fat diet. The results were surprising to anyone who had not already experienced the satiety that is possible through a properly formulated low-carb diet.

Isenhart told Lenzkes she became frustrated witnessing the harm inflicted upon friends and family members who got sick from following the wrong advice. “When I was writing this film, I was writing it for my mom and dad, and for their friends. I think there are a lot of people out there who have been touched by type 2 diabetes. I just hope this film helps people see what they can do to take control of their health.

“We’ve been told the wrong thing for so many years,” Isenhart added. “It’s all about eating real food. There’s no gimmick. I really hope people can walk away with hope and an idea of how they can turn around their health.”

Lenzkes said he was looking forward to recommending the film to his patients searching for answers about the role fats can play in a healthy diet, as well as the harm caused by sugar and excessive carbohydrates.

“It’s important when you see a real life saved and changed,” said Lenzkes. “To me they’re not anecdotes, they’re my patients.”
