Every few months, like clockwork, a new headline appears. "Intermittent Fasting Linked to Heart Disease." "Experts Warn Fasting May Be Dangerous." "Skipping Meals Could Harm Your Metabolism."
You read it. You feel a flicker of doubt. Maybe you even mention it to someone who's been skeptical of your fasting from the start. And they nod knowingly, because of course they do — it confirms what they already believed.
Here's what nobody in that headline tells you: follow the money.
I've been doing one 36-hour fast every week for 25 years. Over 1,000 consecutive weekly fasts. More than 35,000 hours in a fasted state. I'm not writing this from a lab — I'm writing this from 25 years of documented, lived experience. And I can tell you with absolute certainty that the loudest voices calling fasting "dangerous" have a profound financial interest in keeping you at the kitchen table three times a day.
This post is going to make some people uncomfortable. Good. Let's get into it.
The Organization That's Supposed to Protect Your Health — Funded by Kellogg's
When you see a registered dietitian quoted in an article warning about the dangers of fasting, there's a reasonable chance their professional organization — the Academy of Nutrition and Dietetics — has taken millions of dollars from the very companies that need you to keep eating breakfast.
This is not a conspiracy theory. This is publicly documented and reported by The Washington Post, US Right to Know, and the Academy's own financial disclosures.
The Academy of Nutrition and Dietetics: Corporate Sponsors on Record
Let that sink in. The professional body that certifies the "experts" who tell you fasting is dangerous has accepted tens of millions of dollars from companies whose entire business model depends on you eating multiple times per day.
And those same companies paid $20,000 a pop to co-write the nutrition guidance that the public receives as objective science.
The American Heart Association Was a "Platinum Supporter" of Coca-Cola
The rabbit hole goes deeper. Between 2011 and 2016, Coca-Cola and PepsiCo sponsored at least 96 American health organizations — including the American Heart Association, the American Diabetes Association, and dozens of others. Coca-Cola was listed as a "Platinum Supporter" of the AHA.
The same AHA that issues guidance on diet and cardiovascular risk. The same guidance that underpins the articles telling you that fasting — which dramatically lowers insulin, reduces inflammation, and triggers cellular repair — is somehow a threat to your heart.
Meanwhile, researchers from the University of Cambridge found that Coca-Cola's research contracts included clauses that allowed the company to terminate studies that didn't produce favorable outcomes. Science for sale, with a refund policy.
Historical note: In the 1960s, the Sugar Research Foundation (the sugar industry's lobbying arm) paid prominent Harvard scientists to produce studies blaming dietary fat — not sugar — for heart disease. Those studies shaped American dietary guidelines for decades. The scientists were never required to disclose who paid them. This is not speculation. It was documented in JAMA Internal Medicine in 2016.
The "Fasting Is Dangerous" Study That Broke the Internet — And Its Problems
In early 2024, a study made massive headlines claiming that time-restricted eating was associated with a 91% higher risk of cardiovascular death. It went viral. Anti-fasting advocates shared it triumphantly.
Here's what those headlines didn't tell you:
- The study was observational — it tracked self-reported eating windows, not actual fasting protocols. It could not establish causation.
- Participants were not actually following an intentional fasting protocol. Many were eating in a compressed window due to illness, poverty, or shift work — conditions already associated with poor cardiovascular outcomes.
- The study relied on just two single-day dietary recalls to classify participants' long-term eating habits. Two days of memory.
- It did not control for overall diet quality, caloric intake, or pre-existing conditions.
- The American Heart Association — which presented the study — acknowledged its significant limitations.
Researchers who have spent careers studying intermittent fasting called the methodology deeply flawed. The study was, in the blunt words of one expert, "not a study of intermittent fasting."
But the headline had already done its job.
What the Science You're NOT Being Shown Actually Says
Let's talk about what happens in your body during a properly conducted 36-hour fast — the kind backed by decades of peer-reviewed research, not two days of self-reported food memory.
That 500% HGH spike, by the way, is the body's biological answer to the "but you'll lose muscle" crowd. Human Growth Hormone is the primary hormone responsible for preserving lean mass. Your body doesn't want to eat its own muscle — it releases a hormonal flood specifically to prevent it. The research on this has been consistent since the 1980s.
The Nobel Prize connection: In 2016, Japanese cell biologist Yoshinori Ohsumi was awarded the Nobel Prize in Physiology or Medicine for his discoveries of the mechanisms of autophagy — the cellular self-cleaning process that fasting powerfully activates. This is not fringe science. This is the highest scientific honor on the planet, awarded specifically for validating what fasting practitioners have known for centuries.
"But Isn't a 36-Hour Fast Extreme?"
I get this question constantly. And my answer is always the same: extreme compared to what?
Extreme compared to eating breakfast cereal manufactured by a company that paid to write the nutritional guidelines recommending you eat breakfast cereal? Extreme compared to spending every waking hour thinking about your next meal, managing insulin spikes, and wondering why you can't lose weight despite following all the "right" advice?
My protocol is simple: one 36-hour fast per week. For the remaining 5.5 days, I eat what I love — real food, in abundance, without guilt or restriction. No calorie counting. No meal prep containers lined up in the fridge. No supplements I was sold by the same industry telling me fasting is dangerous.
The 36-hour window is not arbitrary. It's the sweet spot: long enough to reach peak autophagy, peak ketosis, and the profound neurological clarity of God Mode (hours 24–36), but short enough to complete once a week and actually sustain for life. I've been doing this since my early twenties. I am not broken. I am not depleted. I am, by every measurable biomarker, in better metabolic health than the vast majority of people half my age who have never missed a breakfast.
So Who Should You Listen To?
I'm not telling you to ignore doctors or dismiss all research. I'm telling you to ask a question that mainstream health media has trained you not to ask:
Who paid for this?
When an organization that took $15 million from Kellogg's, Coca-Cola, and The Sugar Association produces guidance that coincidentally recommends eating breakfast every morning and cautions against skipping meals — that is not objective science. That is a vested interest dressed in a lab coat.
When a study with deeply flawed methodology makes global headlines and a robust, well-conducted body of fasting research gets buried on page 12 — that is not an accident. That is an industry with massive advertising budgets and deep institutional relationships controlling the narrative.
The people calling intermittent fasting dangerous are the same people who told you fat was killing you while quietly funding sugar research. The same people who certified corn syrup as heart-healthy. The same people who invented "the most important meal of the day" as a marketing campaign and then funded the studies to prove it.
I'm not asking you to take my word for it either. I'm asking you to read the footnotes. Check the funding disclosures. Look at who sits on the advisory boards. And then decide for yourself whether the science is clean — or whether it was written by someone who gets paid when you eat breakfast.
A note on safety: Extended fasting is not appropriate for everyone. If you have diabetes, a history of eating disorders, are pregnant, or take prescription medications, please consult a qualified healthcare professional before beginning any fasting protocol. The 36-hour fast described here is the protocol that has worked for me over 25 years — your starting point may look different, and that's completely valid.
The Full Protocol. No Industry Funding. No Conflicts of Interest.
25 years. 1,000+ weekly 36-hour fasts. Every phase documented — the hunger games of hours 0–12, the deep fast of hours 12–24, and the God Mode of hours 24–36. Plus the Re-Seed, Re-Feed, and Maintenance phases that make this a lifestyle, not a punishment.

Is intermittent fasting actually dangerous?
For healthy adults, the scientific evidence strongly supports intermittent fasting as safe and beneficial. The studies claiming it is "dangerous" are largely based on poor methodology and are often produced by organizations with deep financial ties to the processed food industry. Those with diabetes, eating disorder history, or certain medical conditions should consult a physician before starting. But for most healthy adults, the bigger risk is not fasting — it's continuing to eat processed food every 2–3 hours.
Does intermittent fasting cause muscle loss?
The research does not support this for protocols up to 36 hours. Human Growth Hormone spikes by up to 500% during a 36-hour fast — a hormonal response that actively preserves muscle mass. Studies consistently show that people lose the same amount of lean mass whether they fast or follow a standard calorie-restricted diet. The muscle loss concern is largely a myth with no strong clinical foundation.
Who funds anti-fasting research?
The Academy of Nutrition and Dietetics accepted over $15 million from corporations including Kellogg's, Coca-Cola, PepsiCo, General Mills, Mars, and The Sugar Association between 2011 and 2017. Coca-Cola was a "Platinum Supporter" of the American Heart Association. These are companies whose revenue depends entirely on you eating multiple times per day. Check funding disclosures before accepting institutional dietary advice at face value.
What actually happens during a 36-hour fast?
Hours 0–12: glucose burns, insulin falls. Hours 12–16: ketones begin, autophagy initiates. Hours 16–24: deep ketosis, HGH spikes 500%, mental clarity emerges. Hours 24–36: peak autophagy, peak ketosis, peak cognitive clarity — God Mode. The Nobel Prize in Physiology or Medicine was awarded in 2016 specifically for the discovery of autophagy mechanisms.
Is a 36-hour fast once a week sustainable long-term?
Yes — it is one of the most sustainable protocols precisely because it requires only one 36-hour commitment per week while leaving 5.5 days completely free. The body adapts over time: hunger normalizes, energy stabilizes, and the fast becomes something you look forward to. Over 25 years and more than 1,000 consecutive weekly 36-hour fasts, I have not experienced metabolic damage, muscle loss, or any of the dire outcomes predicted by industry-funded critics.
