Description:
In this video we examine the scientific evidence behind resistant starch, including randomized controlled trials showing reductions in body weight, total fat mass, and visceral fat measured by MRI—even when calorie intake remains controlled. We also explore the biological mechanism, including how changes in the gut microbiome may drive these effects.
But there’s an important twist: not everyone responds the same way. We’ll look at new research explaining why some people are “high responders” while others see little benefit, and what role specific gut bacteria play. Finally, we discuss practical ways to experiment with resistant starch yourself—from green bananas to high-amylose maize starch—and how to approach it carefully.

Nick – did I misunderstand you? I believe I heard you say you were going to provide a specific resistant starch brand/product, but I don’t see it. Most of the powders that I have looked at require a large amount of powder to achieve the 40gm goal – this is too many carbs. Help, please. Thank you!
Check out Dr. McDougal's 'Starch Solution'. After watching his forks over knives video I adopted the whole food plant-based nutritional path and got my health back. Cured Diabetes II, reduced weight from 285lbs to 170lbs and have effortlessly maintained that ever since.
Обожаю зеленые бананы !
Why are there tampons in your gut?
Does the same hold true for green plantains?
Resistanant starch type 2
Green banana❤
i started to eat a green banana with my morning greek yoghurt. also in dinner lentils with previous day cooked potato or rice so i hit the resistant starch target along with serotonin production so as to hit 2 targets with the same hammer. will inform on the results
It's yet to be determined whether using Unmodified Potato Starch is going to reduce visceral fat for me. But I will tell you, it will clean you out!! Not like diarehha, but much easier. So at least it has that added benefit.
Great video! Thanks 😊
I mix potato starch and green banana powder 50/50. I take 4 tablespoons a day. First thing with my Huel supergreens and in a shake or smoothie during day. No bloating or discomfort, but the side effect of all that fermentation is methane, CO2. Guess I'm probably a high responder.
mx calories "leave ur body" inst of hvn2b burned ^^ gvn "calories out" a whole new meaning xD rofl
So, can I crunch up dry spaghetti , eat it and get the same effect?
I WISH I could get my son, who's been diagnosed with NAFLD, to try this. He want to take any supplement not recommended by an MD. I sent him links to the published studies in nature metabolism and cell biology 6 months ago. He showed them to his PCP and his hepatologist, and since they'd never heard of them they couldn't recommend he take the supplement. So he won't.
He has lost almost 20% of his body weight over the past year, so kudos to him! But it has not yet made a dent in his MASH. His hepatologist has referred him to a phase 3 drug trial in which he'll be a participant. So if he's not in the placebo group, perhaps that will help.
I love this dude. He’s here to help, not hurt. Anytime I want to know something, I come straight to him.
Wow thats awesome, thanks Nick!! i actually like eating green bananas already 🙂 now i have to find a way to KEEP them green for a while…
Love all your videos but for some reason you talked soooo fast in this one and I couldn’t keep up
You don't poop out fat !
You burn the fat as energy.
The result is CO2 which you breath out and H2O which you urinate out of your body.
You can also fast and visceral fat will shred away FAST!
If you bake a banana then freeze it before putting into a smoothy, does it improve the resistance in the starch?
Fun food hack: Most starchy foods, like pasta, rice, and potatoes, when you refrigerate them, a portion of the starch converts, irreversibly, into resistant starch (type 3. RS3). The longer it's refrigerated, the more converts. (Freezing prevents the conversion. This is why bread goes bad quickly in the fridge, but does fine in the freezer.) We frequently cook our starches in large quantities. If I want pasta, I make 3x what I want to eat. I refrigerate the remaining and eat it in the following days. You can reheat the starch after it's been refrigerated and the resistant starch won't convert back into regular starch.
Thank you for leading me down this path Dr. Norwitz. I started with green bananas and now use the powdered form. I am finding that my AGE index has been dropping into healthy levels!
Your voice drives me crazy. Your program is manic. I could watch you again but infrequently ar best.
It's more like uncooked spagetti
Well no wonder i lost weight eating potatoes that i threw in the fridge lol
Complete nonsense and completely impractical. Buuuut….but the Study…the MRIs!!! Look at all the YouTube Videos of people who tried Resistant Starch and hooked themselves up to a CGM. Insulin spikes almost every time. Who the hell is going to eat 40grams of resistant starch (6 green bananas) a day? Even if you do it for 6 weeks and see a positive benefits what happens when you stop? Oh right, back to baseline. This Doc keeps pushing another Study or another Supplement, and then switches his approach in 6 months when another study or supplement comes out contradicting the first. I started watching this Doc because I thought he provided practical advice but now he's just another Guru pushing the next best thing to keep getting views and feed his Ego. Just eliminate Processed Food, Eat Clean/Low Carb, Intermittent Fast, Exercise and/or Lift Heavy 3x a week, Touch Grass, Sleep Well, and Socialize. You'll live a lot longer and happier without worrying about trying the next promoted Study or Supplement.
9:20 So finaly we pay mice back, do experiments on humans and see how we can help the mice 😂😂😂
I currently put 1/4 cup of chia seeds and 5g of creatine in a shaker with 16 oz of water and shake it vigorously for a minute and drink it first thing in the morning. Sounds like I can add 2 tsp of dried green banana powder to this and pick up some resistant starch too.
I’ve been enjoying your videos recently and your statement that you don’t use AI and showing all of your paperwork is what is causing me to hit subscribe. I categorically skip channels that use AI or don’t show an actual person talking so well done!
So, how are things going now?
i'm wondering if chinese potato starch is ok. it's cheap and chemically the same…
