Move Like This After Eating (It Changes Everything)

Video transcription : Move Like This After Eating (It Changes Everything)

You don't have to go to the gym. You don't have to run a marathon. You don't have to do anything crazy. Four very simple exercises that are going to enable your mitochondria to use glucose from your bloodstream to fuel your muscles. And as a result, they will reduce the glucose spike of a meal.

Hello angels, and welcome back to the Glucose Goddess Show. I'm Jessi Inchauspé, a French biochemist who is obsessed — but like in a healthy obsessed fashion — obsessed with helping you understand your body and your health. And today I've put on my exercise shorts cuz we're going to talk about exercising.

So, I want to teach you four really, really simple movements you can do every single day that are going to transform how you feel because they will lower your glucose spikes. Now, it's up to you if you want to do all four or if you want to choose one. Let's start with one, okay? Pick one and then you can build up. So, I pick one exercise in this episode that you can do every single day starting today. Promise, promise. Pinky promise. Starting today so that you can feel better.

So, let's get into it. First things first, let's have a little quick look at what actually happens when we move our muscles. So, anytime I move a muscle, whether I'm doing this or I'm doing a squat or I'm doing whatever, here's what's going on. Your muscle, here's an example of a muscle. Your muscles contract. This is what creates the movement.

And in order to contract, it is your little factories inside your cells, your mitochondria, that transform things, notably glucose, into energy to fuel your muscles. So muscles have a ton of mitochondria in them who are creating energy for them. The name of the energy created by your mitochondria is called ATP. The harder your muscle is contracting, the more energy it needs. The longer your muscle is contracting, the more energy it needs.

And your mitochondria to create energy, one of the places they will look for the building blocks is in your bloodstream. Your mitochondria will look for glucose or blood sugar in your bloodstream to convert into energy to fuel your working muscles. And we can use this to our advantage.

And today I'm going to show you these four very very simple exercises. You don't have to go to the gym. You don't have to run a marathon. You don't have to do anything crazy. Four very simple exercises that are going to enable your mitochondria to use glucose from your bloodstream to fuel your muscles and as a result they will reduce the glucose spike of a meal.

During a meal if we eat too many carbs and sugars. Carbs are things like bread, pasta, rice, potatoes, oats and sugars are anything sweet from a cookie to an apple. If we eat too many carbs, so too many starches and sugars, that's going to create a big glucose spike in our body. Now, these spikes have damaging consequences. We want to reduce them.

Here's an example. If you have a “pain au chocolat" — I love pains au chocolat — you will create a big glucose spike in your body because a pain au chocolat contains a lot of carbs and sugars. This glucose spike will lead to inflammation, glycation, insulin release, and during the dip after the spike, you might want more sugar because dips after spikes can lead to cravings and hunger. You might feel tired, too.

So, reducing our glucose spikes is really key to feeling our best today and also to help our body prevent long-term chronic diseases. I have a whole episode on how glucose is linked to diseases and people without diabetes. Check it out if you want more.

But today's episode is all about reducing these spikes in very easy ways. So if after you've eaten something high in carbs and sugars, after you've eaten something that would create a glucose spike, if you get in there and before that food has time to create a glucose spike, you activate your muscles.

Your muscles will grab some of the glucose from that meal thanks to your mitochondria and they will turn it into energy to contract instead of letting all that excess glucose create a damaging glucose spike in your body. So that's the whole point of today's episode.

It's about four really easy exercises you can do to reduce the glucose spikes after you eat something high in carbs and sugars.

The first exercise I want to talk about is called the soles push-up or the calf raise. So imagine you're at your desk, you're at work, you're at school, wherever you've eaten something really high in carbs. Here is the easiest and most discreet way you can lower the glucose spike of that meal.

You will simply put your feet on the ground like this and then just go up and down. Try to keep your shoes on. Don't do it like me. So you go, "Oh my god, my shoes are getting off." Anyway, it doesn't matter. You go up and down like this, okay? For five, 10 minutes.

Now, why is this helpful? Because your calves, my dears, contain a muscle called the soleus muscle. The soleus muscle has been shown in studies to be extra good at soaking up glucose in the bloodstream after we eat. The study is called A potent physiological method to magnify and sustain soleus oxidative metabolism improves glucose and lipid regulation.

So in this study the researchers asked participants to do calf push-ups, calf raises for 5 hours. Okay, that's too much. But what they found was that doing 5 hours of calf raises reduced by 52% the post-meal glucose spike and reduced by 60% any extra insulin levels that were there.

Now we don't have to do this for 5 hours. We really don't. But we should know that even doing 10 minutes can have a strong impact. This is my own test. So pain au chocolat versus pain au chocolat and then 10 minutes of calf raises. As you can see, a much smaller glucose spike.

And it's very discreet. It's very, very easy. So, I recommend you test this out. This was my first example of an easy exercise you can do throughout the day to reduce your spikes. You want to do this within like 90 minutes of the end of eating your meal because 90 minutes is about when your glucose levels will peak after eating.

Now, let's talk about a tried and tested very simple exercise that I'm sure that you have probably done before. The exercise is called walking.

So in the study called The effect of a single bout of continuous aerobic exercise on glucose, insulin and glucagon concentrations compared to resting conditions in healthy adults: a systematic review, meta-analysis and meta regression — yes, it is a very long study title with a very simple conclusion — walking after eating reduces the glucose levels in your body.

Which makes sense because as we're walking, our legs, our arms, our torso are contracting to help us walk. And as they are contracting to help us walk, the muscles that are contracting need energy. And the first place these muscles will be looking for energy to give to their mitochondria to create ATP is in our bloodstream.

So, as a result, walking after eating is a very, very easy way to reduce the glucose spike of a meal. How much walking are we talking about? 10 minutes is enough.

Here's a really cool test I did on a poke bowl with a bunch of rice in it and it had this sweet sauce that created a big glucose spike. And then the same poke bowl with 10 minutes of walking. As you can see, it significantly reduces the glucose spike of that meal.

So within an hour and a half after eating, grab a colleague, put a podcast on, whatever, and walk for 10 minutes around the block. It can be up and down the stairs at your office building if you can't go outside, on a treadmill if you want. Just walk for 10 minutes. It'll help you feel much better.

It will curb your cravings and your fatigue for the rest of the day if you had any that were created by glucose spikes and glucose drops.

Now, for a long time, we thought that walking was kind of the best and the easiest thing to do. But a recent study is showing us that this third option I'm about to mention, while it's a little bit weird, is actually very powerful.

The study that is enlightening us today is called Enhanced muscle activity during interrupted sitting improves glycemic control in overweight and obese men. So in this study, the scientists wanted to compare 30 minutes of walking after eating versus doing 10 air squats every 45 minutes for 9 hours.

Again, this is a study situation. We don't necessarily have the ability to do 10 air squats every 45 minutes for 9 hours. But in the interest of science, here is my example of it.

So as you can see here, a big bowl of pasta and then a 30-minute walk and then no movement for 9 hours. My glucose level stayed quite high. We see a bit more roller coaster going on versus that same bowl of pasta with 10 air squats every 45 minutes for 9 hours.

Now, I would never draw conclusions based on my own individual test. That's not what I'm doing here. I'm illustrating what the scientists found on a big cohort of people in their study.

So, it appears, as you can see in my own results, that doing air squats — 10 air squats every 45 minutes for a long time — reduces our glucose levels more efficiently than walking for 30 minutes.

So, if you prefer that, try it out. Every 45 minutes, 10 air squats. You don't have to do nine hours. That's a lot. Maybe even once or twice or three times could be super helpful.

It just shows us that different kinds of exercises that take more or less time and effort have different impacts on our glucose levels. So that was option number three. If you love squats, put a little timer on and after eating do 10 squats, 45 minutes later 10 squats and maybe a third time. Again, you don't have to do it nine times. That's a lot. But a few squats for a couple hours after eating — easy. Check it out. See what you think.

And now my final exercise option, my final suggestion, is extremely easy. So let's say you have an apartment or a house wherever you live. Odds are after you eat or throughout the day you got to tidy things in your house.

A very easy way to get movement in after eating is to do a small house chore. So after eating your meal, your dinner, perhaps within 90 minutes you get up and you tidy your kitchen. Perhaps you have to fold some laundry. Perhaps you have to vacuum your house.

So you grab your vacuum cleaner and you vacuum for 15 minutes like I'm doing in this example. As you can see, a donut on its own, big glucose spike; a donut, and then some vacuuming for 15 minutes — much smaller spike.

Simple exercise snacks, they're called. So simple movements that we do on a day-to-day basis — if we organize them and plan them after a meal high in carbs, it can help our body process the carbs better and reduce the consequences.

So that's number four. Doing a simple house chore, for example, after dinner can be super helpful.

And one more thing I want to mention about why exercising to reduce a glucose spike can be so helpful and such a wonderful thing to do.

Generally, in our body after we experience a big glucose spike, our body tells our pancreas to send out a hormone called insulin. Insulin's job is to grab all the excess glucose in our body and store it away in various storage units to reduce the glucose spike, get our glucose levels to come back down. And that's great. That's normal.

The problem is, over time if your insulin levels increase every single day, multiple times for days, weeks, months, years, over time that accumulation of a lot of insulin can cause its own issues like insulin resistance, like pre-diabetes or type two diabetes.

What's great about moving after eating as a way to reduce your glucose spikes is that your muscles, when they uptake — when they absorb glucose after you eat — they don't need insulin to do so when they're contracting.

So, you're reducing your glucose spike without increasing your insulin levels. And this is so cool and so great because one of the ways that you could reduce somebody's glucose levels would be by just giving them a ton of insulin. But the problem is, as I explained, high insulin levels have their own consequences.

So by using your muscles after eating, you're not only reducing your glucose spike so that you feel better — better energy, fewer cravings, less hunger, less inflammation — you're also helping your body not release too much insulin, which is a very good and healthy thing.

So there we have it. Those were my four examples of really easy exercises you can do every day: the soles push-up like this (the calf raise), the walking, the air squats if you want, or the simple house chore.

Now, moving after eating is just one of my 10 glucose hacks. And if you want to see all of them, which don't require as much physical activity, I promise the other ones are about food, download in the description of this episode my PDF with my 10 core glucose hacks that will help you reduce your glucose spikes, feel amazing today, and help your body and your health in the long term as well.

Thank you for watching. I'll see you next time.

You don’t need to join a gym. You don’t need to train for a marathon. You don’t even need fancy equipment. To flatten your glucose spikes, all it takes is a few simple movements you can do anywhere, anytime.

These aren’t workouts. They’re tiny little “exercise snacks” that help your muscles soak up glucose right after you eat, turning it into energy instead of letting it linger in your bloodstream. The result? Fewer spikes, fewer cravings, steadier energy.

Why movement lowers glucose spikes

When you move, your muscles contract. Contracting muscles need fuel, and the first place they’ll look for energy is your bloodstream – pulling in glucose and turning it into ATP (energy) inside your mitochondria (those amazing little factories in your cells).

This is incredible for two reasons:

1. Instead of glucose from your meal hanging around in your blood, it’s being burned off as energy.

2. Muscles don’t need insulin to absorb glucose while they’re contracting. That means you can reduce spikes without triggering high insulin levels (because constantly high insulin levels can lead to insulin resistance over time).

So basically: movement after meals = steadier energy, fewer cravings, less inflammation, and long-term protection for your body.

Movement #1: Calf Raises (a.k.a. Soleus Push-Ups)

This one is so discreet you can do it under your desk, at school, or even in a meeting.

Simply place your feet flat on the floor and raise your heels up and down, like a mini push-up for your calves. Do this for about 5–10 minutes after eating.

Why it works: your calf muscles – especially the soleus muscle – are particularly powerful at soaking up glucose after a meal. In fact, studies show calf raises can significantly reduce both glucose spikes and insulin levels. (read study)

Movement #2: A 10-Minute Walk

One of my classic hacks. And science is clear about it: walking after eating lowers blood sugar. (read study)

Just 10 minutes is enough to make a difference. You can stroll around the block, go up and down the stairs at work, or hop on a treadmill. The key is to do it within 90 minutes of finishing your meal – that’s when glucose levels usually peak.

Bonus: walking also curbs cravings, keeps your energy stable, and helps with digestion and mood.

Movement #3: Air Squats

Yes, squats! But don’t worry, just a few are enough.

In one study, participants did 10 air squats every 45 minutes for 9 hours. The result? Lower glucose levels than from walking alone. (read study)

But you don’t need to go that far – just try a set or two of squats in the couple of hours after a high-carb meal.

They’re quick, effective, and can be done anywhere.

Movement #4: House Chores

This is my favorite because it’s built into daily life. After a meal, instead of collapsing on the couch, do a 15-minute house chore.

Vacuum the living room. Fold laundry. Tidy up the kitchen. Even light chores activate your muscles enough to flatten glucose spikes.

In my own tests, something as simple as vacuuming after a donut noticeably reduced the spike compared to sitting still.

Glucose Goddess vacuuming helps blood sugar levels

My take-away message

These four easy movements – calf raises, walking, squats, or chores – are simple “exercise snacks” you can sprinkle into your day. They don’t require crazy willpower, expensive equipment, or a gym membership. Just a bit of movement after meals to help your body process carbs more smoothly.

And here’s why this is such a game-changer: every time you flatten a glucose spike, you’re not only helping yourself feel better in the moment (more steady energy, fewer cravings, less post-meal fatigue) — you’re also protecting your long-term health.

Big spikes followed by big crashes create inflammation, speed up aging through glycation, and put extra pressure on your pancreas to release insulin. Over time, this can lead to insulin resistance, type 2 diabetes, and many other chronic issues. But when you move after eating, your muscles take in glucose without needing extra insulin. That means your body stays balanced, your cells stay healthier, and you reduce the risk of long-term complications.

So it’s not “just a walk” or “just a few squats.” It’s a powerful tool to help your body every single day — and to take care of it for years to come.

FAQ'S

Why does moving after meals reduce glucose spikes?

When your muscles contract, they need energy. The first place they grab it from is your bloodstream, in the form of glucose. Your mitochondria (the little energy factories in your cells) turn that glucose into energy, flattening your spike naturally.

How long should I move after eating?

Even 10 minutes is enough to lower a glucose spike. The key is to do it within about 90 minutes of finishing your meal, since that’s when glucose usually peaks.

Which exercise is the most effective?

All four of the exercises I mentioned in this episode have been scientifically proven to work (calf raises, walking, squats, and chores). Studies show walking and calf raises are especially powerful, but the best one is the one you’ll actually do consistently.

Can flattening spikes really improve my long-term health?

Yes! Every time you reduce a spike, you’re helping your body avoid inflammation, energy crashes, and insulin overload. Over the long run, this lowers your risk of insulin resistance, type 2 diabetes, and other chronic conditions — while giving you steadier energy and fewer cravings day to day.

Do I need to go to the gym to flatten my glucose spikes?

Nope! You don’t need a gym, special gear, or a big time commitment. Just a few minutes of simple movement after eating — like calf raises, a short walk, a few squats, or even tidying up your home — can make a big difference.

How soon after eating should I move?

Aim to get moving within 90 minutes of finishing your meal — that’s when glucose levels usually peak. Even a short 10-minute walk or a few minutes of calf raises in that window can make a big difference.

What other hacks can I do to lower my blood sugar?

Movement is just one of the 10 Glucose Goddess hacks. Others include having a savoury breakfast, eating a veggie starter before your meal, putting clothes on your carbs, and enjoying sugar as dessert after a meal instead of on an empty stomach. You can download the 1-pager of my 10 hacks here.
