Do Insulin Spikes cause weight gain and diabetes?

Should we worry about Insulin "spikes"? Is it healthier to keep our insulin flat at all times? Do insulin spikes cause weight gain, insulin resistance and diabetes? A new study looks at all these questions.

This is one of my favorite channels. I need to watch more! Thanks for what you do.

I'm a newgrad dietitian and I really appreciate the way you fairly break down research in a concise manner. Thanks for helping us all!

As somebody who has stubborn genetic glucose problems despite being skinny, avoiding junk food and getting lots of exercise, I had taken particular interest in this video. Heard just about every suggestion and had taken the advice: 1. reduce refined carb intake (I rarely had any). 2. get more exercise (been lifting weights since 1995 and do five hours a week of cardio). 3. lose weight (so much that my ribs show). 4. don't eat naked carbs * the endocrinologist had said always have protein, fat and fiber with your meal to try and reduce the blood sugar spike. I used to think that eating a number of small meals over the course of the day was preferable to "stabilize blood sugar levels". After having viewed this video and, earlier, the video with Nicola Guess, I had started moving back to three meals a day and with only light snacking in btwn (but not overeating). In particular, I have reduced the size of my dinners, and eating in the evening. Let's see if my morning fasting glucose improves any.

An obvious question would be - how does insulin spikes correlate to insulin resistance? Given the fact that we have been told many times that the majority of americans are pre diabetic, it would seen this study contradicts that information. Please do a video from your point of view on this question

The refutations of Gary Taubes just keep on coming. I love it.

Really eye-opening. I've been assuming large insulin spikes after meals are always bad. Makes me rethink things. Thank you.

While I have more questions after watching this video than I had before, it is undoubtedly the kind of information we need more of. We need to question the common sense truths regularly to get better information to make better decisions.

Thank you! I saw an interview of your with this woman diabetes doctor from England, I remembered one thing clearly that she said. "who says that your glucose levels have to be a flatliner all the time" The body was created in such a way to handle glucose.Of course, diet etc is important and it doesn't mean you have to eat sugars and processed foods. Clean healthy eating, exercise and living! I would really appreciate more data/information on this subject.

WHat is your view on the Kraft Test?

Because Dr. Joseph Kraft did a way better study and identified 5 insulin patterns that give a lot of information. These patterns are:


Pattern I: Normal insulin sensitivity and response. Insulin levels rise and fall appropriately after glucose ingestion.

Pattern II: Insulin levels rise higher than normal but return to baseline within a reasonable time. This pattern indicates insulin resistance but not as severe as in later patterns.

Pattern III: Similar to Pattern II but with insulin levels staying elevated for a longer period, indicating more significant insulin resistance.

Pattern IV: Characterized by very high initial insulin responses and prolonged elevated insulin levels, indicating severe insulin resistance.

Pattern V: This pattern was later added to describe individuals with high fasting insulin levels and an exaggerated response to glucose ingestion, indicating severe insulin resistance and dysfunction.



Would you consider doing a video on the Kraft Test? I am sure your audience would really appreciate it.

Am I the only one NOT surprised by this chart? All the food mentioned there seems to have an appropriate insulin reaction based on my understanding. Jellybeans being the highest makes sense since they're mostly just raw glucose, right? Then donut being pretty high but not as high as jellybeans also makes sense, due to the dough slowing down digestion, which is also the reason pasta ranks lower than potatoes, which are starchier and become much more digestible during cooking. With chips, I think the argument would be that the nutritional value is greatly reduced, and therefore probably the carbohydrate contents compared to full potatoes.. Then lentils vs beans is also not surprising as well. Beans are MUCH starchier than lentils, so it makes sense for them to rank higher. And as for oats being really low, I thought this was known? High fiber and relatively high protein (for a mainly carb-type food), makes perfect sense. And as for beef/fish being roughly the same as apples, that's another pretty obvious one to me. Apples are known to be a low glycemic food (fiber & pectin), and fish/beef are high in
protein, which, especially when consumed with minimal carbs, some of which gets converted into glucose...

Pathologizing a normal process... The results of the pasta was surprising.

Great video, but I'm afraid some people in the comment section are conflating insulin spikes with glucose spikes. Simply because insulin spikes don't seem to be particularly harmful, doesn't mean that glucose spikes are harmless.

Hit it out of the ballpark once again.

[naturefan]

All very interesting. I wore a cgm on and off for about 6 months, as a non diabetic trying to help various symptoms. I found that I felt worst, headaches, palpitations, when my glucose levels were flatter. My doctor agreed that it was best to go with my symptoms rather than trying to control the spikes.

I stopped wearing the cgm and have learnt enough to greatly improve my symptoms, less frequent urination, no bedtime loo visits and sleeping all night, but I’ve still got plenty of big glucose spikes!

Very intelligent and honest review of this study, and good advice.
Thank you!!! 👍🧡

[descai]

Could you do the same video but on glucose spikes?

[jaythardin]

This is great news. Going back to eating some of my favorite foods. Another great informative video.

[richards]

I am 78, pre diabetic, and just recently got a CGM to test for myself which foods cause my blood sugar to rise or spike more than others. and at what time of day as well. For sure it is an interesting experiment, and I feel is worth the hundred or so dollars. And yes I am more comfortable avoiding the spikes and trying too keep it somewhat stable. Enjoy your videos.

What about glucose spikes?

It would've been interesting to see the blood sugar levels in the same diagrams as the insulin levels.

Really great, thought-provoking scientifically sound information. Thank you for providing it!
