Do This Move Immediately After Eating (Reduce Blood Sugar By 52%!) — Transcript
Full transcript
- 0:00Did you know that there is a very small,
- 0:02hidden muscle deep in your calf that
- 0:05most people have never, ever heard of?
- 0:09And it turns out to be one of the most
- 0:11useful muscles in your entire body for
- 0:14controlling your blood sugar. So, a few
- 0:17years ago, researchers at the University
- 0:19of Houston found that activating this
- 0:22one muscle while you are just sitting
- 0:24down in a chair could cut the spike in
- 0:28blood sugar after a meal by around 52%.
- 0:33I want to be completely crystal clear
- 0:36from the beginning of this video. This
- 0:39is obviously a fascinating study, but it
- 0:41isn't just some magic fix that I'm
- 0:44trying to get you to do instead of
- 0:46everything else I talk about. The real
- 0:48value is the lesson that this research
- 0:52study teaches us, which is just how
- 0:54powerful movement can be for your body.
- 0:58So, in this video, I'm going to explain
- 1:01what this muscle is, why blood sugar
- 1:04spikes are so damaging in the first
- 1:06place, and the clever back door that
- 1:09your muscles use to deal with those
- 1:12blood sugar spikes, and then finish with
- 1:14the much bigger takeaway that I think
- 1:16matters even more than the muscle
- 1:19itself. And if you find this video
- 1:21useful, if you find it fascinating like
- 1:24I did when I first read about this
- 1:26study, then please just like the video,
- 1:29give it a hype as well, and subscribe to
- 1:31the channel. I promise you, it means so,
- 1:34so much, and it makes all the difference
- 1:36for the growth of this channel. Let me
- 1:38start with the problem that we're
- 1:41actually trying to solve here, you know,
- 1:42the point of this video. So, when you
- 1:44eat a meal with carbohydrates in it, the
- 1:47sugar floods into your bloodstream, and
- 1:50if it comes in, you know, in too big a
- 1:52quantity and too fast, you get a really
- 1:56sharp spike. And that spike is harmful
- 1:59in two ways. The first one is that sugar
- 2:03in your blood is sticky and it's
- 2:05irritating to the delicate lining of
- 2:07your blood vessels. So, every big spike
- 2:10does a little bit of damage and that
- 2:12compounds over years and decades.
- 2:15The second one is that to clear it, your
- 2:18pancreas has to release a big surge of
- 2:21insulin, which is the hormone that
- 2:23pushes sugar out of the blood and into
- 2:26your cells.
- 2:28The thing is though, sometimes that
- 2:29surge of insulin overshoots. It drags
- 2:33your blood sugar down lower than when it
- 2:35started, which is this classic afternoon
- 2:38crash that we all feel.
- 2:40You know, the tiredness and the brain
- 2:41fog and the sudden craving for something
- 2:44really sweet.
- 2:45And if you do that a few times a day for
- 2:47years on end,
- 2:49then two things will happen. Your
- 2:52pancreas gets, you know, a bit worn out
- 2:54from pumping out all of that insulin and
- 2:57your cells then eventually stop
- 2:59responding to it, which is what we call
- 3:02insulin resistance.
- 3:04And that is the road that leads
- 3:06step-by-step to pre-diabetes
- 3:09and then type 2 diabetes. Now, here's
- 3:12where it gets really interesting because
- 3:14your muscles have a very clever trick.
- 3:17Normally, getting sugar out of your
- 3:19blood and into your cells, it requires
- 3:22insulin, which acts like a key unlocking
- 3:25the door so that sugar molecule can just
- 3:27flow straight in.
- 3:29But when a muscle actually contracts,
- 3:31when you use it, like walking or squats
- 3:35or whatever,
- 3:36it can open up a completely separate
- 3:39door and pull sugar straight out of your
- 3:41bloodstream without needing much insulin
- 3:44at all.
- 3:46So, the point here is that a working
- 3:48muscle can mop up the sugar from your
- 3:51last meal directly, taking the pressure
- 3:53off your pancreas, and then flattening
- 3:56that spike.
- 3:58And this, honestly, is one of the most
- 4:00powerful ideas in all of exercise
- 4:03medicine, because it means that movement
- 4:05does far more than just burning
- 4:08calories. It actively helps your body
- 4:11manage its blood sugar in real time.
- 4:15And this brings us on to that little
- 4:17muscle in the calf, this tiny
- 4:20insignificant muscle that nobody has
- 4:22heard of, which is called your soleus
- 4:26muscle. So, the soleus is the deep
- 4:28muscle that keeps you upright whenever
- 4:31you're standing, and it's built very
- 4:33differently from most of your other
- 4:36muscles. And that difference is that
- 4:38your soleus muscle is made almost
- 4:41entirely out of slow, enduring fibers.
- 4:44So, it can keep contracting for hours on
- 4:47end without getting tired, which is very
- 4:50different to the other muscles around
- 4:53your body, like your bicep or your
- 4:55quads, where if you were to do bicep
- 4:57curls for hours or squats for hours,
- 5:00well, nobody could, could they? Because
- 5:02those muscles get tired really quickly.
- 5:04But your soleus muscle in your calf is
- 5:08very different. And rather than relying
- 5:10on its own stored fuel, it prefers to
- 5:14pull glucose and fat straight from your
- 5:17blood.
- 5:18And that makes it almost perfectly
- 5:20designed to keep clearing sugar for a
- 5:23long time while you barely move. And
- 5:27that is exactly what the Houston
- 5:29researchers actually tested. So, they
- 5:31had people do a slow, repeated heel
- 5:34raise while seated, you know, keeping
- 5:37the soleus muscle gently working. And
- 5:40they compared it to simply sitting still
- 5:43after a sugary drink. The result was
- 5:45that the post-meal sugar spike dropped
- 5:49by up to 52%
- 5:51and the amount of insulin needed fell by
- 5:54up to 60% 60%
- 5:58So, one, you know, tiny muscle working
- 6:02away while the person sat in a chair did
- 6:06a huge amount of the heavy lifting that
- 6:09would normally fall to your pancreas by
- 6:12releasing insulin. Now, let me just be
- 6:14really clear here. This was a small
- 6:16study done in a lab using a pure sugar
- 6:19drink rather than a normal mixed meal
- 6:23and it was designed to understand how
- 6:25the body works, not to prove that just
- 6:28twitching your calves and raising your
- 6:30heels beats going for a walk or going to
- 6:33the gym.
- 6:34So, let me be really, really explicit
- 6:36here. Doing this after your meals is far
- 6:39better than doing nothing, but on its
- 6:43own, it will not undo a diet full of
- 6:46ultra-processed food and it will not
- 6:49make you fit or healthy by itself. It
- 6:52doesn't mean that, you know, you only
- 6:54need to train your calf muscles and it
- 6:56certainly, obviously, doesn't reverse
- 6:59diabetes.
- 7:00All it's really showing us is just how
- 7:02powerful movement and muscle can be.
- 7:06But, taken for what it is, it's really
- 7:09useful in two ways. The first one is
- 7:11that for somebody who's frail or
- 7:13recovering from an illness like a
- 7:15pneumonia or a fracture somewhere or
- 7:17they simply cannot move around much, a
- 7:20gentle seated heel raise for a few
- 7:23minutes after your meals is a brilliant
- 7:26option and it's far better, like I said,
- 7:28than just sitting completely still
- 7:30for the rest of the evening. The second
- 7:33one is,
- 7:35you know, think about the long game
- 7:36here. A modest cut in your sugar spike
- 7:40after one meal, it might not sound like
- 7:43an awful, you know, big deal here. But
- 7:46if you do that after every meal, every
- 7:49day for 10 or 20 or even 40 years, then
- 7:53that cumulative reduction really does
- 7:55add up to real protection for your blood
- 7:58vessels and your pancreas and your
- 8:01long-term risk of lots of different
- 8:03diseases. But for me, really, the
- 8:05biggest lesson in this study isn't your
- 8:09soleus muscle at all.
- 8:11Just stop and think about it for a sec.
- 8:13If isolating one small muscle in your
- 8:16calf while you sit completely still can
- 8:19do this much work. And I get that your
- 8:20soleus muscle is a bit different to your
- 8:22others, but just take this point for a
- 8:24second.
- 8:25If isolating just one muscle is this
- 8:28powerful,
- 8:30just imagine what a 10-minute walk after
- 8:33a meal could do. Because with a walk,
- 8:36you're not just using one muscle, one
- 8:38tiny muscle in one particular part of
- 8:41your body. You are using your calves,
- 8:44your thighs, your glutes, and your core,
- 8:46and swinging your arms all at once. And
- 8:49you're getting a bit out of breath
- 8:51while you do it as well.
- 8:53That is many, many times more muscle
- 8:57pulling sugar out of your blood.
- 9:00But then take it one step further and
- 9:02imagine what it means to be gently
- 9:04active all day long, not just walking
- 9:08after your meals, but being active as
- 9:11often as you can throughout the day in
- 9:13between your meals. And this is the
- 9:16whole point for me. Our bodies are built
- 9:19to use our muscles constantly, not just
- 9:22in one hard burst followed by nothing.
- 9:25And this study is a beautiful
- 9:27illustration of just how powerful even
- 9:30the smallest bit of muscle work can be.
- 9:33It's exactly why by people who potter
- 9:36about all day, who garden, who do their
- 9:39cooking and their cleaning and they walk
- 9:41to the shops and they walk to see their
- 9:43friends and family.
- 9:44These people so often stay strong and
- 9:46sharp and live well into their 90s and
- 9:50beyond. But what does this actually look
- 9:52like in practice in our modern world?
- 9:55Well, the simple version is to stop
- 9:58sitting down like a stone the moment you
- 10:01finish eating.
- 10:03If you can, the best option is a
- 10:07after your bigger meals, but preferably
- 10:10after every time you eat something. But
- 10:12if a walk isn't possible, then do some
- 10:15seated heel raises like they did in the
- 10:17study by lifting your heels up and down
- 10:19for a few minutes or a handful of squats
- 10:22or even just pottering around, you know,
- 10:24anything, doing the washing up, doing
- 10:25the cleaning, you know, anything that
- 10:28stops you being sedentary and static
- 10:31after you eat. Anything that gets your
- 10:33muscles working in that hour after you
- 10:37eat will, I promise you, it will make a
- 10:39massive difference. And this matters
- 10:41more and more as you get older because
- 10:43from around the age of 30 or 40, we
- 10:46naturally start to lose muscle in a
- 10:49process called sarcopenia. And less
- 10:52muscle means less ability to actually
- 10:54clear sugar from your blood. So, the
- 10:57older you get, the more it pays to keep
- 11:00those muscles active and to hold on to
- 11:03as much of them as you can. So, you
- 11:06don't need anything fancy to look after
- 11:09your blood sugar. You just need your own
- 11:10muscles and a bit of movement at the
- 11:13right time of the day or preferably
- 11:16throughout the entire day if you can. If
- 11:18you work in an office, then investing in
- 11:21a rising desk like this, let me just
- 11:23show you, investing in a rising desk
- 11:26like this means that you can stand up
- 11:28for most of the day and you can do some
- 11:31heel raises or some squats every 10 or
- 11:3315 minutes. So, why don't you start
- 11:36really small this week by taking a
- 11:38really short walk after your evening
- 11:40meal or just doing a few minutes of heel
- 11:42raises while the kettle boils. And, you
- 11:45know, let that small addition to your
- 11:48routine become a habit. And then once
- 11:50you get used to that, just add a bit
- 11:52more on and a bit more on. Because the
- 11:55real secret that our bodies are trying
- 11:57to tell us is that staying gently active
- 12:01all day every day is one of the most
- 12:03powerful things that you can do for a
- 12:05long and healthy life. So, I hope you
- 12:09found that video useful. I thought this
- 12:10study was so, so interesting when I read
- 12:13it. And again, just take a look in the
- 12:16description of this video and you'll see
- 12:17all of the different references, the
- 12:19links for these different studies. And
- 12:21please send it to somebody if you think
- 12:24they will find it useful as well. Have a
- 12:27great day and I will see you in my next
- 12:30video.
