Your body can only change so much in a single day. The sooner you accept that, the more consistent you will become.
It does not matter whether your goal is cardiovascular fitness, strength, or weight loss. There is a biological ceiling on how much adaptation can happen in any 24-hour window. Fighting that reality is what causes most people to quit.
Here is what I tell my patients. Build a system you trust. Commit to it for six weeks. Then — and this is the part most people get wrong — stop monitoring your progress until those six weeks are up.
Checking the scale every morning, scrutinizing yourself in the mirror every few days — it is one of the most demoralizing things you can do to yourself.

You are looking for evidence of change in a window too short for change to be visible.

Of course it looks like nothing is happening. That does not mean nothing is happening.

If you genuinely accept that your body is doing the most it can do each day, then the logical conclusion is simple: trust the system, stop looking up, and let the time pass.

Six weeks from now you will have a real data point. And most people who do this are genuinely surprised by what they find.

Life is won by inches. Stick to the plan and do not look up until you hit that six week mark.

Here is what 36 hours of fasting actually feels like — the honest version.

Hungry? Not really. By this point the hunger has largely passed, which surprises most people who have never pushed past the early stages of a fast.

Energy? I would describe it less as energetic and more as restless. You do not want to sit still. As long as I am moving I feel genuinely good. The moment I stop and try to sit quietly is when it gets uncomfortable. So the answer is — keep moving.

Sleep was okay. I woke up a few times. My body was clearly having some opinions about the situation. We had a brief conversation about short rib tacos and agreed to revisit the topic later.

For anyone who is afraid to try this — it is more manageable than you think. But it requires preparation. Do several weeks of intermittent fasting first before attempting an extended fast. Train your body to run without a constant glucose supply before you ask it to go this long.

Stay hydrated. Keep moving. Moderate exercise throughout. The hunger passes, the energy levels out, and the results speak for themselves.

36 hours into a fast — here is exactly what peptides I am using and why.

Two categories.

The first is a growth hormone secretagogue. I use Ipamorelin specifically. It is short-acting and works by augmenting your own natural growth hormone pulse — it is not a growth hormone molecule itself. The result is increased muscle preservation and enhanced fat breakdown during the fast, which is exactly what you want when you are in a prolonged calorie deficit.

The second category is a growth hormone fragment — the specific segment of the growth hormone molecule responsible for lipolysis, meaning fat breakdown. Researchers essentially mapped the growth hormone molecule, identified which portion drives fat loss specifically, and synthesized that segment on its own. I alternate between two options here.

HGH Fragment 176-191 is the exact peptide sequence from your own growth hormone. The downside is it breaks down relatively quickly, so you may need to dose two to three times a day to maintain the effect.

AOD 9604 has a slight synthetic modification that makes it more stable and longer lasting. Both are effective — I rotate between them based on preference.

I personally do not mind multiple dosing. I actually prefer the quick on, quick off profile because it more closely mirrors how physiological processes naturally work.

One important note: these peptides are not a shortcut. If you are not in a calorie deficit and not exercising, they will not overcome that. They are a tool that works on top of the fundamentals — not instead of them.

If you want the full protocol — exactly what I use, when I take it, and how I structure it around a fast — type FASTING PEPTIDES in the comments and I will send it to you.

“There is no data to support that.”

I have heard that line used to dismiss treatments, supplements, and procedures more times than I can count. And after 20 years in practice I want to tell you what it actually means most of the time.

It means nobody paid for the study.

Here is a real example from my own practice. I perform a procedure called a medial branch block and radiofrequency ablation on the spine. It targets the nerve that innervates the joints from the top of the spine all the way down to the tailbone. Insurance has covered it in the neck and the lower back for years because those areas were studied extensively and the data exists.

The thoracic spine — the mid-back — uses the exact same nerve with the same function. The anatomy is consistent throughout. But for years Medicare and most insurers refused to cover it there, citing a lack of supporting data.

So why was there no data? Not because the procedure did not work. I have a full roster of patients who paid out of pocket because it worked and they knew it. The data did not exist because there was no financial incentive to generate it. No pharmaceutical company profits from proving a procedure works. No academic career is advanced by studying a mid-back nerve block. So nobody studied it.

Medicare just changed its position this year and now covers it. The procedure did not change. The anatomy did not change. The money finally moved.

This matters enormously when evaluating nutrition, supplements, and emerging treatments. Absence of data is not evidence of absence. It is often just evidence of absent funding.

Keep that in mind every time someone uses “no data” as a conversation-ender. I will be coming back to this concept in future videos on nutrition and supplements.

I want to tell you about a moment early in my career that changed how I evaluate medical data forever.

I was at a conference and a presenter stood up and told a room full of physicians the following: OxyContin is safe, effective, and carries a very low risk of addiction.

We now know that was catastrophically false. It contributed to one of the worst public health crises in American history.

Here is what that claim was built on. A single letter — not a study, a letter — written to the New England Journal of Medicine in 1980. It looked at addiction rates in hospitalized patients in a narrow and poorly designed way. Purdue Pharma took that letter and used it to market OxyContin aggressively while shaming physicians who pushed back.

I did not prescribe it. Not because I had access to better data, but because I understood the physiology. One OxyContin pill was equivalent in potency to roughly ten Percocet. They wanted me to give it twice a day. I knew from basic pharmacology that flooding op**te receptors that aggressively would downregulate the receptor profile, suppress the body’s own endogenous production, and create a cycle where patients actually felt more pain over time — not less. That is why short-acting op**tes used sparingly and rotated between molecules is the correct approach.

The data told one story. The physiology told another. The physiology was right.

So how do you protect yourself from bad data presented with authority? Two options. Learn enough about the underlying physiology to evaluate claims yourself — that is the gold standard. Or find two or three people who are rigorous, credible, and genuinely invested in getting you accurate information, and follow them closely.

That is what this channel is built to be.

People tell me I am just making expensive urine when I talk about taking vitamins every day.

Here is my counter to that.

Let me show you what actual vitamin deficiencies look like — not theoretical risks, real documented disease states.

Vitamin D deficiency leads to osteopenia, osteoporosis, elevated fracture risk, proximal muscle weakness, increased susceptibility to respiratory infections, and in severe cases a bone disease called osteomalacia. There is a receptor for vitamin D on nearly every immune cell in the body. Deficiency has consequences.

Vitamin B12 deficiency causes megaloblastic anemia, peripheral neuropathy, poor wound healing, and significant cognitive decline. In profound deficiency it can progress to spinal cord degeneration. That is not a minor outcome.

Vitamin C deficiency causes scurvy, poor wound healing, joint pain, and anemia. We have known this for centuries.

These are not fringe claims. These are well-established disease states caused by the absence of nutrients your body requires to function.

So when someone tells me I am wasting money on vitamins, my answer is simple: it costs me about $1.50 a day to give my body more than it needs. And with water-soluble vitamins there is no meaningful downside to taking more than necessary. Even with the fat-soluble vitamins — D, K, and A — it takes a significant effort to reach toxic levels.

The question is not whether vitamins work. The question is why you would wait until you are deficient to care.

Here is one of the core reasons I take vitamin C and vitamin D every single day — and it comes down to understanding what is actually happening inside your body as you age.

The free radical theory of aging goes like this. Reactive oxygen species — essentially unstable molecules — are constantly interacting with your DNA, your mitochondria, and other critical cell functions.

Over time that damage accumulates.

There is a strong argument that this is one of the main reasons cancer rates are dramatically higher in older populations than younger ones.

Your native ability to neutralize these things is robust when you are young and declines steadily over time.

So what can you actually do about it?

Two things.

First, you can take supplements that directly neutralize free radicals. Vitamin C is the classic example. It attacks and neutralizes reactive oxygen species — the tradeoff is that the vitamin C molecule is consumed in the process, which is why consistent daily intake matters.

Second, you can optimize your immune system’s own ability to seek out and destroy abnormal cells before they become a problem. Natural killer cells do exactly that — they identify precancerous cells and eliminate them. Vitamin D is critical here. There is a receptor for vitamin D on nearly every immune cell in the body. That is not a coincidence.

The free radical theory of aging is probably correct. Your body’s native defenses decline with age. These supplements support both lines of defense with no meaningful side effects.

That is enough for me.

People ask me all the time what supplements I actually take. Here is the honest answer.

A multivitamin every day. When I am fasting I use a gentler formula that agrees with my stomach. When I am eating normally I switch to a higher potency option. Simple rule — the best supplement is the one you will actually take consistently.

D3 and K2. I take between 15,000 and 20,000 IU daily and monitor my levels twice a year. Despite that dose my levels stay in normal range — which tells you how deficient most people are running without even knowing it.

Zinc at 50mg. Critical for immune cell function and for holding onto your hair as you age. Both matter.

Magnesium glycinate at 400mg. There are two forms of magnesium out there. Take whichever one your stomach tolerates. A slightly less optimal form you actually take is worth more than the perfect form sitting in your cabinet.

NAD — that deserves its own video and it will get one.

Fish oil for inflammation and lipid support.

The broader principle: do not build a supplement stack you cannot sustain. If you are taking 20 things and feeling terrible, you will quit. Research, spread your dosages throughout the day, and find the combination you can stick with long term.

Consistency wins every time.
