The Insulin & Glucose Doctor: This Will Strip Your Fat Faster Than Anything!
Dr. Benjamin Bikman (guest), Steven Bartlett (host), Narrator, Narrator
In this episode of The Diary of a CEO, featuring Dr. Benjamin Bikman and Steven Bartlett, The Insulin & Glucose Doctor: This Will Strip Your Fat Faster Than Anything! explores metabolic scientist reveals insulin resistance as hidden driver of modern disease Dr. Benjamin Bikman argues that insulin resistance is the metabolic root cause linking many chronic conditions—from type 2 diabetes and obesity to Alzheimer's, infertility, hypertension, and certain cancers. He explains in simple terms how insulin works, why most modern lifestyles keep it chronically elevated, and how that drives fat gain, inflammation, and organ damage over time. The conversation covers fast versus slow pathways to insulin resistance, ethnic and gender differences in fat storage, environmental contributors like air pollution and vaping, and the pros and cons of ketogenic diets and GLP‑1 drugs like Ozempic. Bikman then outlines four practical dietary pillars and emphasizes muscle-building exercise as key tools to restore insulin sensitivity, extend healthspan, and sustainably lose fat without wrecking metabolism.

Key Takeaways
Insulin resistance underlies many major chronic diseases, not just diabetes.
Conditions like Alzheimer's ("insulin resistance of the brain"), hypertension, PCOS, erectile dysfunction, fatty liver disease, and some cancers often share a common metabolic core: tissues stop responding properly to insulin while insulin levels remain chronically high.

Chronic high insulin—driven mainly by frequent refined carb intake—makes and keeps you fat.
Insulin is the primary hormone that tells fat cells to store and hold onto energy; eating carbohydrate-heavy, frequent meals keeps insulin elevated all day, enlarges fat cells, and gradually creates "slow" insulin resistance that's hard to reverse.

Where and how you store fat matters more than how much.
Small, numerous subcutaneous fat cells are relatively healthy, while large, overfilled fat cells—especially in visceral (belly/organ) fat—promote inflammation and systemic insulin resistance; ethnicity and sex strongly influence fat cell number, size, and distribution.

Ketosis can accelerate fat loss and sharpen cognition when done correctly.
By lowering insulin and increasing ketones, a ketogenic diet shifts the body to burn more fat, raises fat tissue metabolic rate, provides the brain with an efficient fuel, and can improve energy stability—provided protein is adequate and overall calories aren’t chronically too low.

Muscle mass is a powerful protector against insulin resistance and early death.
Skeletal muscle is the main sink for blood glucose and becomes highly insulin-independent when contracting; resistance training and maintaining muscle are better predictors of longevity than aerobic fitness alone and greatly aid glucose and insulin control.

GLP‑1 drugs like Ozempic reduce hunger but can erode muscle and bone.
Clinical trials suggest ~40% of weight lost on high-dose GLP‑1 agonists comes from lean mass, which may be irreversible in older adults; used without strength training and high protein, patients risk regaining fat on a smaller, weaker frame when they stop the drug.

Four practical pillars can lower insulin and improve metabolic health.
Bikman recommends: (1) control carbohydrates—especially refined ones from boxes and barcodes, (2) prioritize protein, ideally animal-sourced, (3) don’t fear the natural fats that come with protein, and (4) once adapted, use structured fasting judiciously, especially if not already in ketosis.

Non-diet factors like stress, sleep, vaping, and pollution also drive insulin resistance.
Acute stress hormones, inflammation from infections, inhaled toxins (cigarette smoke, vaping aerosols, diesel exhaust), and some endocrine-disrupting chemicals can rapidly induce insulin resistance—even without weight gain—showing it’s not just about calories in/calories out.

When we're looking at smoking versus vaping, vaping is probably worse in terms of the damage to the airway and the insulin resistance that comes from it. But this gets worse because we know that insulin resistance is the core for most chronic diseases that are killing us, and there's a handful of other lifestyle habits that's contributing to it.
That's horrifying. So tell me everything.
Dr. Benjamin Bikman is a leading metabolic scientist-
... whose research focuses on the hidden epidemic of insulin resistance and its devastating consequences.
And by regaining control of your insulin levels, he says you can regain control of your life. Insulin is a hormone that affects literally every single cell of the body, but if those cells become insulin resistant, you start to spread the disease. For example, they call Alzheimer's insulin resistance of the brain. And even the most common forms of infertility, erectile dysfunction and PCOS, insulin resistance is a heavy contributor. Now, 88% of adults in the US have some degree of insulin resistance, and people hear this and think America's just fat and metabolically sick, but we're not actually the worst country when it comes to this. And part of it is because of how different ethnicities store fat, and I'll come back to that. But there's two roads to insulin resistance. So there's the fast lane, and I could make you insulin resistant in six hours with either of these common three things, but if I removed them, your resistance would go away just as quickly. Now, the slow lane, that's a problem, and there's certain lifestyle habits and problems with our diets that are massively contributing to slow insulin resistance. Now, thankfully, this can be resolved through four pillars, which are very simple.
We'll get into that, but why don't we just sack all this off and just take Ozempic?
Well, because people may not know about the negative side effects. For example, 40% of the weight that people are losing on these drugs is coming from-
Holy (beep) . (coin clanging) I have been forced into a bet with my team. We're about to hit 10 million subscribers on YouTube, which is our biggest milestone ever thanks to all of you, and we wanna have a massive party for the people that have worked on this show for years behind the scenes. So, they said to me, "Steve, for every new subscriber we get in the next 30 days, can $1 be given to our celebration fund (coin clanging) for the entire team?" And I've agreed to the bet. So if you want to say thank you to the team behind the scenes at Diary of a CEO, all you've gotta do is hit the subscribe button. So actually, this is the first time I'm gonna tell you not to subscribe (laughs) because it might end up costing me an awful... (laughs)
(coins clattering) Woo! Woo!
(chill music) Benjamin, what is the mission that you're on?
