In this live AMA, JJ Virgin challenges common nutrition myths and provides evidence‑based guidance on three core areas: (1) meal frequency and timing, emphasizing a limited eating window, adequate protein per meal, and avoiding food intake 2–4 hours before sleep; (2) creatine supplementation, detailing its biosynthesis, the methylation cost of endogenous production, the comparative potency of creatine HCl versus monohydrate, especially for women, and the rationale for combining HCl with taurine and magnesium to improve absorption and reduce GI distress; (3) resistant starch, describing its role as a fermentable prebiotic that boosts butyrate‑producing gut bacteria, its benefits for insulin sensitivity, satiety, and gut barrier function, while acknowledging that in certain gut‑dysbiosis states (e.g., SIBO, low stomach acid, FODMAP sensitivity) it may exacerbate symptoms. Virgin also addresses related concerns such as GLP‑1‑induced slowed gastric emptying, the importance of digestive enzymes, and practical snack recommendations, arguing that a protein‑focused snack earlier in the day is preferable to carbohydrate‑fat heavy options before bedtime. Throughout, she stresses nuance over absolutist claims and encourages personalized testing (e.g., gut microbiome panels) to tailor interventions.

It used to be that people were like, you have to get up, eat breakfast, have a snack, eat lunch, have a snack, have dinner, have a snack. That's ridiculous. The last thing you wanna do is eat right before bed. That's the worst possible thing you can do. The people who get the most attention on the internet make the biggest claims. They go down this rabbit hole of absolutes, and science is never that way. Resistant starch can affect the gut microbiome positively. Potentially there could be a negative, just like fructooligosaccharides. It depends on the situation. This is a completely overgeneralized claim. It's not a fact. Hello, welcome to Ask Me Anything. Excited to be with you today. Our Q&A topic for today, for this week, is nutrition and healthy metabolism. So we're gonna be doing a full Q&A on nutrition. So anything you've been curious about, there's a few questions in here I think are gonna completely change the way you think about metabolism, and healthy aging. So let's dive into it. From Dana, she says, people really underestimate the brain side of creatine. Also interesting on HCL, not talked about enough. Have you seen a difference in women specifically? Okay, so there's a couple really wild things going on. I want to give you some insight into this, pull back the kimono on creatine for women. 95% of creatine's in our muscle, 5% in our brain. I have heard— now some of this is just theoretical— is that our muscles. It's like we prioritize it in our muscles. This makes no sense to me. It would seem like you should prioritize your brain, but apparently your muscles— you need to have enough so that you have enough then for your brain. We make a gram or two of creatine a day from amino acids: methionine, glycine, arginine. Turns out, for your body to make that creatine is very— it is the most expensive process we do in our body to do this, using something called methylation. So it uses your B vitamins, your methyl donors to do this. It's very expensive. So things like B12 and SAMe, um, 5-methyltetrahydrofolate, are things that we use to methylate. This is the thing that taxes your methylation system the most. So if you're one of those people who's a poor methylator, has that 5-MTHFR SNP, like, the last thing you want to have to do is have your body have to work harder to make creatine because you're not getting enough supplementally. Okay, so that's the first part. Our body makes a little bit. We should be getting it from food. You have to eat a gram, a pound of raw or rare meat or fish, or 2 pounds of cooked animal protein to get about a gram of creatine. That is a ton. Like, I personally can eat that, but I think we're probably not getting that in, right? Can we agree? It turns out that if you, if you take in more creatine, your body will, will balance out by slowing, slowing down or shutting down its own production of it. Not forever, but just while you have enough on board. Which is awesome because then you protect those methylation pathways so they can do other important things like lower homocysteine. How cool. What the studies have shown is that about 750 milligrams of HCL equals about 5 grams of monohydrate. But when they've done the brain research, and I don't know if the form gets into the brain better or what, 750 milligrams of HCL they found helped women have faster processing speed, better cognition, better mood. And this was a menopause study. So these are preliminary research, you know, there's not a gazillion of them, but I mean, that's pretty amazing. I know what it does for me. So, and now you hear on the, on the monohydrate side, people are saying, oh, have 10 grams, 20 grams. But I don't know if you've taken that much monohydrate. You feel like crap. It's, it's distressing to your GI. You bloat. The other thing I want to point out is I took HCL and I combined it with taurine. Why? Think of taurine. Think of, like creatine is your performance engine, right? Well, taurine's like a cooling and fluid system. It helps your body with cell hydration, you not feeling that bloatiness going on, right? So we used to always do taurine and B6 to help people not retain water during their periods. So taurine's really good for that. We also brought magnesium in because magnesium is really the activator here. The ATP, which is your energy source in your body, is really magnesium ATP. You need um, magnesium to make sure your body can actually use the creatine. So they— that's why I put HCL, creatine, and taurine together. There is no other product available that has that. I have the exclusive on it. That is shiitine. It is amazing. If you guys want to use it, just cover the S, it becomes creatine. It's totally fine. But yes, so likely 750 milligrams is going to do you fine. I tend to use more But I'm also 6 feet tall and I drive myself pretty darn hard. So between hard workouts, hard mental stress, I do tend to do at least 2 servings a day, sometimes more if I'm time zone adjusting. So that is from Dana. I know they're dropping questions into chat and they're adding questions over here. If you're watching this, it would super duper help me out if you would subscribe, subscribe, follow, um, wherever you happen to be hanging out. I am doing this live through YouTube. It will live on YouTube after this.. So if you'd like to come and refer back to it, that's where it will be. I do a lot of cool videos on YouTube too, and boy does it help me out if you subscribe. So it would really help me if you'd do that. I just read Georgi Dinkov say that resistant starch can feed endotoxin-producing gut bacteria, thereby promoting inflammation. To avoid low glycemic starches such as green bananas. Okay. There are some people out there and I, I, it's funny, I also coach healthcare practitioners and help them build their brands. And one of the things I've warned all of them about, and I think it's the challenge out there. Is that the people who get the most attention on the internet make the biggest claims, and they, they go down this rabbit hole of absolutes, and science is never that way. This is a completely overgeneralized claim. It's not a fact. Green bananas contain something called resistant starch. So do cool potatoes, cooled rice. Now, resistant starch can affect the gut microbiome positively Potentially there could be a negative, just like fructooligosaccharides can be great for the microbiome but negative. It depends on the situation. In most cases, this is something that you should be doing and can be amazing because they're rich in resistant starch. And resistant starch is this really cool starch that's not digested in the small intestine. It goes to the colon where the microbes feed on it, and that's what you want. It's kind of like a prebiotic in that it can increase some bacteria, it decreases others. In most cases, what you see with resistant starch is that it increases the production of these short-chain fatty acids, especially butyrate. And butyrate is amazing. It's one of those things when you do a gut health test like Tiny Health or Vibrant Wellness, it's one of the things you look for. And a lot of times you end up having to supplement. I'm— I've been supplementing. I just did hellacious rounds of antifungals, antimicrobials, antibiotics after my Amazon trip. I'm restoring my gut now. Did Tiny Health test. Now I'm on a couple different things, a pendulum, Polyphenol Booster. I'm on BodyBio's Tudca and their butyrate. That's one of the big things that showed up was a problem with butyrate. Butyrate helps with your leaky gut, with gut barrier function. So if you feel worse doing some of these things, this is what you need to check because here it's kind of a— it's its own little like lab test. If you take Resistance Surge and you feel bad, I want to know why. Do you have SIBO, small intestinal bacterial overgrowth? Here's the reality. If you are on a GLP-1, it slows down gastric emptying. This can actually potentially lead to some small intestinal bacterial overgrowth if you have low stomach acid, which— this is why I always tell people you should be taking Protein Digestive Enzymes. That's something that we've been doing for years, especially if you're increasing your protein. But these were actually— our protein enzymes now are moving to a comprehensive formula to help you. They've always been a comprehensive, not just protein but fat and carbs too, but it's really focused on helping restore the gut and gut enzymes. But if you have any kind of SIBO, right, um, or a FODMAP sensitivity, which will tend to be— it depends on how ripe the banana is— you might feel worse if you do. The real question is why, because these things should be really, really helpful to you. The idea that resistant starch feeds endotoxin-producing bacteria is is kind of outrageous to say. So the reality is these, um, these bacteria, they're called LPS. They come primarily from gram-negative bacterial cell walls. Whether food increases it really has to do with what's going on with your gut. Is your gut messed up? Are you inflamed? Do you have poor metabolic health? This comment of just avoid that is— I completely disagree. And I would also say that if you're struggling with any of these things, because what we know is resistant starch— it's why our extra fiber is a focused resistant starch product because resistant starches help with insulin sensitivity, butyrate production, fat burning, satiety, bowel regulated— like, regularity, um, post-meal glucose response, right? Super important. This idea that everybody should avoid this and they're inherently inflammatory is wrong. But when you say these inflammatory things online, you get a lot of attention, and that person in particular is known for doing that. Okay, meanwhile, Shannon says, is there a healthy nighttime snack? I'm eating organic organic oatmeal, blueberry, and raw almond butter. The goal is to stabilize blood sugar but need to reduce belly fat. What is a better time to eat that snack? Oh, I'm glad you asked this. So here's the reality: why are you eating this snack? Why are we snacking? So what you really want to do is you want to eat 3 meals, maybe 1 snack during the day, and you want to eat during a smaller window. So you should eat about an hour or 2 after waking up in the morning. You need like an hour at least, but 90 minutes or so for your pancreas to come online. You get up in the morning, go out, see the sun, bring your cortisol up, get your melatonin down, get your organs firing, get your insulin going so that when you eat, your body's ready. And then you're going to eat every 3 to 5 hours. And so think about if you had breakfast around 8, maybe you have lunch around 12 or 1, dinner around 6. You want to stop eating 2 to 4 hours before bed. 2 hours is the minimum, longer is better. The last thing you want to do is eat right before bed. That's the worst possible thing you can do. When you're sleeping, you should be sleeping, not digesting. If your stomach's full, it's hard you cannot raise growth hormones. So you don't want to do that. So you want to stop eating 2 to 4 hours before bed. You shouldn't be hungry if you're eating correctly, which means eating protein first, optimizing protein to 0.7 to 1 gram per pound of target body weight, at least 30 grams of animal protein, 40 grams of plant at a meal. You're getting in that 10 grams or more of fiber at that meal. You're getting in a lot of fluid before or after. If you're eating that way, you You shouldn't be hungry. So maybe you've trained yourself to have that snack. I know that, that it used to be that people were like, you have to get up, eat breakfast, have a snack, eat lunch, have a snack, have a— have dinner, have a snack. Oh my gosh, that's ridiculous. Stop eating a couple hours before bed. If I'm going to eat a snack, I'd rather see a little protein hit snack. So I don't love the oatmeal, blueberry, and raw almond butter because that's basically fat and carbs. You don't— don't kid yourself that almond butter is high protein. It's high fat. You can't be high and high. So you can either have high protein or high fat, but you can't have high protein, high fat. So almond butter is basically 90% fat, and oatmeal and blueberries are carbs. So this is a protein-fat slam. So if you want to stabilize blood sugar, you actually don't need to eat to do that. Eat protein with fiber and you'll have good blood sugar control for a long period of time, right? Last thing you want to do is eat before you go to bed when your melatonin's up, your cortisol's down, your insulin production's down, because you'll wake up with higher fasting blood sugar and mess that whole thing up. So a better time to eat that snack would be never, and the next better time would be between, you know, breakfast and lunch or lunch and dinner, depending on what your timing is, you know. And for some people, they need to eat 4, 4 smaller meals a day. Sometimes it's 3 meals, sometimes it's 2 meals. See what works the best for you.
