We all know that taking a walk after meals can be one of the most useful things you can do for blood sugar.
But what happens when you can't walk?
Maybe you're stuck at your desk, sitting through a long meeting, traveling on a plane, or simply don't have the time.
In this episode, Robby Barbaro breaks down research on one surprisingly small muscle in your calf called the soleus and explains how activating it while sitting may help your body clear glucose from the bloodstream without relying entirely on insulin.
In one study, sustained soleus activity reduced the post-meal glucose response by 52% and reduced the amount of insulin needed by 60%. But there's an important catch: those results came from keeping the muscle active for about three hours, not from a quick five-minute exercise.
In this episode, you'll learn:
• Why walking after meals can help lower blood sugar
• How contracting muscles can take up glucose through a pathway that does not require insulin
• What GLUT4 transporters are and why movement activates them
• Why the soleus muscle is uniquely suited for long periods of low-intensity activity
• How to activate the soleus while sitting at a desk or in a chair
• Why this simple movement can be useful during meetings, flights, or long periods of sitting
• Where the widely shared "52% lower glucose spike" claim actually comes from
• Why the full effect required hours of continuous movement in the original research
• What a newer study in people with prediabetes found about post-meal glucose
• Why larger muscles like your quads and glutes may produce more benefit when you only have a few minutes
• How a few minutes of squats or repeated sit-to-stands can provide another option
• Why movement helps manage glucose that is already in your bloodstream but does not replace addressing insulin resistance at the root
The seated movement itself is incredibly simple.
Sit with your feet flat on the floor and keep your toes planted.
Raise your heels like you're performing a seated calf raise, then lower them slowly and gently.
Repeat at a comfortable pace for as long as practical.
The goal isn't intensity. It's keeping the soleus muscle quietly working during time you would otherwise spend completely sedentary.
But here's the catch.
The dramatic results you may have seen shared online did not come from doing a few calf raises for five minutes.
In the original study, participants kept the muscle active for approximately three hours while their bodies processed glucose.
So if you only have a few minutes, Robby explains that using larger muscle groups may make more sense. Squats, repeated sit-to-stands, stairs, or a short walk recruit much more muscle at once.
The bigger lesson is flexibility.
You can use a lot of muscle for a short period of time, or a small muscle like the soleus for a longer period while you're already sitting.
And neither strategy replaces the bigger goal.
Movement helps your body deal with glucose that is already circulating after a meal. Improving insulin sensitivity over time requires addressing the underlying metabolic environment as well.
If you're taking glucose-lowering medication, talk with your healthcare provider before making significant changes to your exercise or movement routine.

In this episode, Robby Barbaro explains a simple calculation you can make using two numbers that are probably already on your standard lipid panel: your triglycerides and HDL cholesterol.
By dividing your triglycerides by your HDL, you get what's known as the triglyceride-to-HDL ratio—a measurement researchers have studied as a potential clue to insulin resistance and metabolic health.
But there's an important catch.
This ratio is not a diagnosis, and there is no single cutoff that can tell everyone whether they are insulin resistant.
In this episode, you'll learn:
• How to calculate your triglyceride-to-HDL ratio using a standard lipid panel
• Why researchers became interested in this ratio as a marker of insulin resistance
• Why insulin resistance can cause triglycerides to rise while HDL decreases
• What research suggests about higher triglyceride-to-HDL ratios and future type 2 diabetes risk
• Why a ratio around 3.5 has appeared in some research—but should not be treated as a universal diagnostic cutoff
• How sex, ethnicity, genetics, medications, alcohol intake, fasting status, and metabolic health can affect the interpretation
• Why a low ratio doesn't automatically prove you're insulin sensitive
• Why a high ratio doesn't automatically mean you have insulin resistance
• Why people following a low-fat, whole-food, plant-based diet sometimes see their HDL decrease
• Why a lower HDL number isn't necessarily a problem when triglycerides, blood sugar, blood pressure, and other markers are improving
• Why trying to raise HDL simply for the sake of raising the number may miss the bigger metabolic picture
• How food quality matters—even within a plant-based diet
• Why insulin resistance can begin developing years before fasting glucose or A1C becomes abnormal
• How this simple ratio can help you ask better questions about your metabolic health
The calculation itself is simple:
Triglycerides ÷ HDL = Triglyceride-to-HDL Ratio
For example:
Triglycerides: 60
HDL: 50
60 ÷ 50 = 1.2
Robby explains that ratios around 1 or below generally represent a favorable pattern, while ratios around 1.5–2 can also be reassuring.
Once the ratio begins moving above roughly 2–3, it may be worth looking more closely at the rest of your metabolic picture. Ratios above approximately 3–3.5 have been associated with insulin resistance in a number of studies.
But these are not diagnostic zones.
A ratio of 2.9 doesn't prove you're insulin sensitive, and a ratio of 3.1 doesn't automatically mean you're insulin resistant.
Think of the number as a clue—not a verdict.
The bigger lesson is to avoid becoming obsessed with any single lab value.
Look at your triglycerides, HDL, glucose, blood pressure, fasting insulin when available, diet, and overall metabolic health together.
Because sometimes the early warning signs of insulin resistance may already be sitting in your medical records long before blood sugar reaches the prediabetes or type 2 diabetes range.

Seeing a high number on your glucose meter can be stressful.
In this episode, Robby Barbaro shares two simple, free strategies you can use in the moment to help bring blood sugar down—while also stepping back to explain why blood sugar gets high in the first place.
You'll learn how stress hormones can affect liver glucose output, why slowing your breathing may help calm that response, and how even a short period of movement can help your muscles pull glucose from the bloodstream.
In this episode, you'll learn:
• Why stress and anxiety can raise blood sugar
• How cortisol and adrenaline can signal your liver to release more glucose
• Why a longer exhale can help activate the parasympathetic nervous system
• How to use a simple 4-second inhale and 6-second exhale breathing pattern
• Why this technique may be especially useful when you're feeling anxious about a high glucose reading
• How 10–15 minutes of movement can help lower blood sugar
• Why muscle contraction allows glucose to move into muscle cells through a pathway that does not rely on insulin
• Why even something as simple as walking can be a useful tool
• How these immediate strategies fit into the bigger picture of insulin resistance
• Why managing a high number in the moment is different from addressing the root cause over time
The first strategy is simple:
Breathe in through your nose for 4 seconds, then breathe out slowly through your nose for 6 seconds. Repeat this pattern for a few minutes.
The goal is to help shift your nervous system away from a stress response and toward a calmer "rest and digest" state.
The second strategy is movement.
Even 10–15 minutes of light activity, such as walking, can activate your muscles and give glucose another pathway out of your bloodstream.
These strategies can be useful tools when your glucose is running high, but the bigger goal is still to understand and address why high blood sugar is happening in the first place.
And an important reminder: this is not an anti-medication message. Never stop or change your medication without working with your healthcare team.

What if insulin resistance doesn't just start with the food on your plate, but also with what's happening inside your gut?
In this episode, Robby Barbaro explores the connection between your gut microbiome, inflammation, and blood sugar control, and explains why the bacteria living inside your digestive system may play an important role in insulin sensitivity.
You'll also learn why probiotic supplements, despite all the attention they receive, may not be the most reliable way to improve gut health, and why the more powerful strategy may already be sitting in your kitchen.
In this episode, you'll learn:
• How the gut microbiome may be connected to type 2 diabetes
• Why people with type 2 diabetes often have lower levels of certain beneficial bacteria
• How gut bacteria that produce butyrate may help support a healthier intestinal lining
• How an imbalance in gut bacteria may contribute to inflammation and insulin resistance
• Why chronic inflammation can interfere with insulin signaling
• What the research shows about probiotics and blood sugar control
• Why probiotic supplements sometimes produce only modest or inconsistent results
• Why many probiotic bacteria may not survive the acidic environment of the stomach
• How fiber feeds the beneficial bacteria already living in your gut
• Why beans, lentils, whole grains, vegetables, and fruit can support a healthier microbiome
• How gut bacteria convert fiber into short-chain fatty acids like butyrate and acetate
• Why these compounds may help support insulin sensitivity and glucose metabolism
• How even simple dietary changes can begin shifting the gut microbiome
• Why resistant starch from beans, lentils, and cooked-and-cooled potatoes, rice, and pasta can help feed beneficial bacteria
The key takeaway isn't that you need to find the perfect probiotic supplement.
It's that you can create a healthier environment for the beneficial bacteria you already have.
Fiber-rich whole plant foods provide the fuel those bacteria need to produce compounds that support gut health, reduce inflammation, and help your body respond to insulin more effectively.
Rather than trying to manage your microbiome from the outside in, this episode shows you how to support it from the inside out with the foods you eat every day.

What if you could eat the exact same bowl of rice, piece of bread, or serving of pasta—but get a dramatically different blood sugar response simply by changing how you prepare it, what you eat with it, and what you do afterward?
In this episode, Robby Barbaro breaks down four practical tools that can help reduce post-meal blood sugar spikes without eliminating carbohydrate-rich foods from your diet. But more importantly, he explains why these strategies are only supportive tools—the ultimate goal is to improve insulin sensitivity so your body can process carbohydrates more effectively in the first place.
In this episode, you'll learn:
Why two people can eat the exact same plate of pasta and experience completely different blood sugar responses
How insulin sensitivity influences what happens after you eat carbohydrates
How cooking and cooling rice, potatoes, or pasta can increase resistant starch
Why beans, lentils, chickpeas, and split peas naturally contain resistant starch
How resistant starch may help slow digestion and support healthier glucose and insulin responses
Why the order you eat your food can change your post-meal blood sugar response
How starting with vegetables and plant protein before eating starch may help reduce glucose spikes
Why even a short 5–10 minute walk after eating can help your muscles clear glucose from your bloodstream
How muscle contraction activates GLUT4 transporters and allows glucose uptake with less dependence on insulin
Why simple movements like wall sits, squats, or calf raises can also be useful after meals
How barley and oats use beta-glucan fiber to form a natural gel that slows digestion
How combining several of these strategies in the same meal may create a greater effect than relying on one alone
One example might look like this:
Cook and cool your starch, add lentils or beans, start your meal with vegetables, include barley or oat groats, and then take a short walk afterward.
Each strategy targets a different part of the glucose response—from digestion and absorption all the way to how quickly your muscles remove glucose from your bloodstream.
But there's an important distinction.
These tools can make individual meals easier to manage, but they don't replace the bigger goal: improving insulin sensitivity at the root.
Robby explains how following a low-fat, whole-food, plant-based approach over time can help reduce the accumulation of fat inside muscle and liver cells, allowing insulin signaling to work more effectively. As insulin sensitivity improves, you may find that you need fewer of these meal-by-meal strategies because your body becomes better at processing carbohydrate-rich foods on its own.
And instead of treating your glucose meter like a report card, use it as feedback. Track your fasting glucose and your response after meals, experiment with these strategies, and watch for trends over time.
The goal isn't to fear bread, rice, pasta, potatoes, or other carbohydrate-rich foods.
It's to create a body that can process them more effectively.
