In this episode, we break down Increased Lipolysis and Lipodystrophy in simple terms. Learn how fat spillover blocks insulin, when TZDs help or harm, and the food and exercise steps that work.

This is Part 4 of our 12-part series, “Anything Meds Can Do, You Can Do Better.” Today we dig into Increased Lipolysis and Lipodystrophy—what they mean, why they drive insulin resistance, how certain meds work, and the simple steps you can start now.

Remission from type 2 and prediabetes is real. Let’s go.

Episode in one sentence

When fat breaks down and spills into places it doesn’t belong, it gums up your muscles and liver, blocks insulin and GLUT4, and pushes blood sugar up—but food choices, movement, and smart habits can turn the tide.

What we cover

• What “increased lipolysis” really means (extra fat breakdown and spillover)
• How fat inside muscle makes the “sponge” greasy and insulin can’t work
• Toxic fat byproducts (diacylglycerols and ceramides) and how they block insulin and GLUT4
• Lipodystrophy in plain English (fat stored in the wrong places)
• Fatty liver and why it’s so common with type 2 diabetes
• TZDs (pioglitazone/Actos; rosiglitazone/Avandia): how they work, pros, and serious cons
• Food and exercise that improve insulin sensitivity and PPAR-gamma naturally
• Simple, safe action steps you can start this week

Key ideas in simple words

• Increased lipolysis = extra fat breakdown. Lots of free fatty acids (FFAs) float in your blood. They can move into muscle and liver.
• Lipodystrophy = fat stored in the wrong places (like liver, muscle, heart, pancreas) instead of mainly under the skin. That “fat spillover” hurts insulin action.
• Inside muscle, fat droplets break into “toxic byproducts” called diacylglycerols (DAGs) and ceramides. These block insulin signals and stop GLUT4 (the sugar door) from opening. Blood sugar rises.
• Think of muscle as a sponge. Sugar is water. When the sponge is greasy (fat inside), water runs off. The muscles say, “We’re full.” Sugar stays in the blood.
• Fatty liver (NAFLD) is very common with type 2 diabetes. It ties to oxidative stress and the whole “metabolic syndrome” picture.

Meds: the good and the bad (TZDs)

• Names: Thiazolidinediones (TZDs) like pioglitazone (Actos). Rosiglitazone (Avandia) is used less.
• How they work: They turn on a switch in your cell nucleus called PPAR-gamma. This helps:
  • Improve insulin sensitivity
  • Lower FFAs and lipotoxicity
  • Store fat under the skin, not around organs
  • Increase GLUT4 in muscle and fat
  • Ease fatty liver
  • Some studies show fewer repeat strokes/heart attacks in high-risk folks
• Serious cons to know:
  • Fluid and sodium retention → can worsen heart failure
  • Not advised in NYHA class III–IV heart failure (and used with caution in many others)
  • Weight gain
  • Bone loss over time (shifts stem cells toward fat cells, away from bone-building cells, called osteoblasts). This is a big deal for older adults, especially postmenopausal women, due to hip and spine fracture risk.
• Reality check: Many with type 2 diabetes already have heart problems or risk factors (long duration, high A1C, hypertension, CAD, kidney disease, obesity). For a large slice of people, risks may outweigh benefits. Always talk with your clinician.

Natural ways to support PPAR-gamma and improve insulin sensitivity

These are straight from the science and fit real life.

• Omega-3 fats
  • Eat: salmon, sardines, mackerel
  • Or use a quality fish oil (third-party tested for purity)
  • Also: chia seeds, freshly ground flaxseeds
• Polyphenols (colorful plants)
  • Berries (deep red/blue), green tea (EGCG), coffee, dark chocolate/cocoa, turmeric/curcumin
  • Resveratrol (also found in red wine—enjoy mindfully)
  • Quercetin (onions, apples)
• Fiber and short-chain fatty acids
  • Beans and lentils, vegetables, whole grains, seeds (flax, chia)
  • Your gut turns fiber into short-chain fats that help the gut and fat tissue work better
• Monounsaturated fats (heart-helping fats)
  • Olive oil, avocados, almonds, walnuts
  • They improve lipids, calm inflammation, and help insulin work
• Saturated vs. monounsaturated: a quick tip
  • Saturated fats are often solid at room temp (think bacon fat, shortening)
  • Monounsaturated fats are liquid (like olive oil)
  • Nuts are “solid” because of their structure, but their oils (like in natural nut butters) separate and stay liquid
  • Natural peanut or almond butter should list just “nuts” and maybe “salt”—the oil on top is normal. Stir, then refrigerate. Watch out for “natural” jars with added coconut oil (a saturated fat).

Exercise: your daily “GLUT4 button”

• Aerobic exercise (like walking) helps sugar enter muscle even without insulin by moving GLUT4 to the cell surface.
• Resistance training (weights or bands) builds muscle so you can store and burn more glucose. It also helps bones.
• Bone health tip: Lifting heavier (safely) puts helpful stress along bones and wakes up osteoblasts (bone-building cells). This is key for women after menopause.
• Mitochondria (your cell “powerhouses”) work better with regular exercise.
• Good news: Exercise helps even without weight loss. A 5–10% weight loss, if needed, can make fatty liver and insulin resistance much better.

Quick glossary

• Increased Lipolysis and Lipodystrophy: extra fat breakdown and fat stored in the wrong places
• FFAs: free fatty acids from fat breakdown
• DAGs/Ceramides: toxic fat byproducts that block insulin signals
• GLUT4: the “door” that lets sugar into muscle cells
• PPAR-gamma: a cell “switch” that controls fat and sugar genes
• TZDs: meds (like Actos) that turn on PPAR-gamma
• NAFLD: non-alcoholic fatty liver disease

Richie and Amber’s highlights

• “Muscles are like sponges. When they’re greasy, water (sugar) just runs off.”
• “I love exercise because GLUT4 can work without insulin.”
• “If you can’t walk, health can fall fast. Protect bone with resistance training.”
• “Pick one thing to do this week. Small steps add up.”

Pick one action for this week

Choose one and start today:

• Walk 20 minutes every day
• Eat fatty fish twice this week (or take a quality omega-3)
• Swap butter/shortening for olive oil
• Add 1–2 tablespoons of freshly ground flaxseed to yogurt or oats
• Add 1 cup of beans to meals 3 times this week
• Drink green tea daily
• Do 2 short resistance sessions (whole body), even 15 minutes each
• Switch to natural nut butter (just nuts + salt)

Who this helps

• People with type 2 diabetes or prediabetes
• Anyone with signs of insulin resistance (belly fat, high triglycerides, low HDL, high fasting glucose)
• Folks worried about fatty liver or bone health
