We cover Metformin, side effects, and why short walks after meals beat meds for many people.

Episode summary

Today we pick up where we left off on Insulin Resistance in the Muscles. We talk about Metformin (a biguanide), what it does, how it’s used, and the real-life side effects many people feel. Then we share the step-by-step lifestyle moves that work even better than meds for many listeners. You’ll hear why even a 2-minute walk after meals can lower post-meal blood sugar, how to make new habits stick, what to eat more of (and less of), and how the body clears fat from the liver when you change your routine. We keep it simple, real, and doable.

What you’ll learn

• The first line for Insulin Resistance in the Muscles: diet and exercise
• What Metformin does and how it’s usually dosed
• Common side effects (and how to lower the chance of “bathroom runs”)
• Why lifestyle changes beat medicine in a major diabetes trial
• The easiest “switch” you can flip after meals to lower blood sugar
• Foods that help: fiber, beans, greens, lean protein, healthy fats
• Why ultra-processed sugar and flour make things harder
• How movement pulls sugar into muscles even without insulin
• A simple plan you can start today in under 5 minutes

Key takeaways

• Diet and exercise should come first for Insulin Resistance in the Muscles. Metformin is helpful for many, but it’s not the first step.
• In the Diabetes Prevention Program, Metformin cut type 2 diabetes risk by 31%. Lifestyle changes cut it by 58%.
• Start movement small and often. A 2–5 minute walk after meals can lower post-meal blood sugar and help with triglycerides.
• If you and your doctor choose Metformin, reduce side effects by starting low (often 500 mg), going slow, taking with food, and asking about extended release.
• Eat more nutrient-dense, high-fiber foods (beans, veggies, greens, lean protein, healthy fats). Cut back on ultra-processed sugars and refined flour foods (sugary drinks, white bread, pastries).
• Your liver can clear fat within weeks of better food choices and movement. That helps cholesterol and triglycerides.
• Muscle contractions move sugar into muscle even without insulin. Movement gives you control in minutes.

Meds for Insulin Resistance in the Muscles: what to know

• The class is called biguanides. Metformin is the most common.
• What it can do:
  • Helps your body use insulin better
  • Lowers liver sugar output
  • In the DPP trial: 31% lower risk of type 2 diabetes vs placebo
• Side effects:
  • Many do fine
  • Some have nausea and diarrhea (often at bad times)
• How to lower side effects:
  • Start at 500 mg, take with food
  • Increase slowly (every ~2 weeks) toward 1,500–2,000 mg/day if needed
  • Ask about extended release (ER) if your doctor agrees
  • Jumping to the max dose on day one can be a disaster for your gut
• Big picture:
  • Meds can help
  • But first-line is diet and exercise per expert guidelines
  • Real change needs real tools, time, and support

Why lifestyle wins for Insulin Resistance in the Muscles

• In the same DPP study:
  • Lifestyle (food + movement) cut diabetes risk by 58%
  • Metformin cut it by 31%
• Movement after meals:
  • Even 2 minutes helps
  • 2–5 minutes is great; up to 30 minutes is even better
  • Lowers post-meal blood sugar spikes
  • Helps blunt the triglyceride surge from the liver
• Walking is enough:
  • If you’re sedentary, this is the perfect start
  • Indoors works too (hallway laps, stairs, marching in place)

Make it stick: habit stacking (easy start plan)

• Week 1: Pick your biggest meal. Walk 2 minutes right after you eat.
• Week 2: Add a second meal. Walk 2 minutes after that one too.
• Week 3: Add the third meal. Bump your walk to 3–5 minutes if you can.
• Tips that work:
  • Keep shoes by the table or door
  • Set a timer when you put your fork down
  • Walk inside when it’s hot, cold, or rainy
  • Pair it with music or a short phone call
  • Track checkmarks to see wins add up

Food choices that help

• Aim for nutrient density: more nutrition per calorie
• Eat more:
  • Vegetables and greens
  • Beans and lentils (fiber and “resistant starch” that slows spikes)
  • Lean protein (fish, chicken, eggs, tofu)
  • Healthy fats: mostly monounsaturated and omega-3s (olive oil, avocado, nuts, seeds, fatty fish)
• Cut back on:
  • Ultra-processed sugars and refined flour foods: sugary drinks, white bread, cakes, donuts, candy
• About “white foods”:
  • It’s a simple rule some use, but not perfect
  • Some white foods are great (onions, garlic, cauliflower, white peaches)
• A simple cue:
  • Foods that need more chewing often have more fiber and help you feel full
• What changes in your body:
  • Fat can clear from the liver within weeks of better eating
  • HDL can go up; triglycerides can come down
  • LDL particles can get “fluffier,” which is less risky
  • Less visceral fat means less internal “fire” around organs

How movement lowers sugar fast

• When your muscles contract, they open tiny “gates” that pull sugar in
• This can happen even without insulin
• That’s why a short walk after meals works so quickly

Quick start checklist

• After each meal, walk 2–5 minutes (indoors is fine)
• Drink water instead of sugary drinks
• Fill half your plate with veggies or salad
• Add beans a few times per week
• Choose lean protein and healthy fats
• Sleep 7–9 hours when you can; lower stress with simple breaths or a short walk
• Be consistent, not perfect

Friendly reminder

• This podcast is for education. It’s not medical advice.
• Don’t start, stop, or change medication without your clinician.
• If Metformin is part of your plan, talk with your doctor about dosing and extended release.
