Podcast: Juicebox Podcast: Type 1 Diabetes
Episode: #1786 – Best of Juicebox: Five Ways to Boost Insulin Sensitivity
Host: Scott Benner
Guest: Jordan Wagner (RN, CDE, person with type 1 diabetes)
Release Date: March 1, 2026

This episode centers on actionable, realistic strategies for anyone—especially those with type 1 diabetes—to improve insulin sensitivity. Host Scott Benner and returning guest Jordan Wagner break down the biological, behavioral, and lifestyle factors that can make your body more responsive to insulin, potentially allowing you to use less insulin for the same effect. The conversation focuses on five key factors: stress, physical activity, sleep quality, nutrition, and sunlight (natural light exposure). The hosts also explore how these factors interrelate, offering both real-world tips and deeper explanations behind the science.

Key Discussion Points & Insights

1. Why Should You Care About Insulin Sensitivity?

• Lower Insulin Doses Can Reduce Fear of Lows
  • Using less insulin means lower risk of hypoglycemia. (03:49)
  • “I often see a lot of people scared of low blood sugars. And so naturally, if you're using less insulin, there's going to be a lower risk of hypoglycemia.” – Jordan (03:51)
• Potential Impact on Weight
  • Excess insulin plus excess calories can promote weight gain.
  • Using less insulin with improved sensitivity may help with weight loss.
• Addressing Stigma
  • Some feel stigma from taking large insulin doses publicly; improved sensitivity lowers dose.
• Caveat: It’s About the Right Dose, Not Chasing a ‘Low Number’
  • Scott cautions against under-dosing for fear of using “too much insulin”, as this can spiral into eating disorders and poor glucose control. (05:11)

2. The Five Major Ways to Improve Insulin Sensitivity

a. Managing Stress (07:20–19:00)

• Stress hormones (cortisol, epinephrine, norepinephrine, glucagon) spike blood glucose and promote insulin resistance.
• Stress responses (e.g., “running from a bear” vs. being stuck in traffic) generate the same hormone surge—but modern stress doesn’t burn off glucose.
• "Insulin’s like the key that unlocks the cells... but if you’re chronically... having these high stress hormones, it like desensitizes the cells to the insulin." – Jordan (09:12)
• Biological analogy: Stress pokes holes in your body's "bucket" of mineral balance, eroding sensitivity further. (15:36)
• Stress, poor sleep, bad nutrition—all compound; one makes the others more challenging.
• Practical advice: Identify stressors and look for ways to build support, community, or seek professional help—even simple changes can help manage ongoing stress. (17:15)

b. Physical Activity (21:02–32:00)

• Movement helps your muscles absorb glucose with limited insulin (“GLUT transporters are like taxi cabs taking glucose to your muscles.” – Jordan, 21:07).
• Activity counters insulin resistance—effects last up to 72 hours after exercise.
• “If you’re doing [exercise], you will likely see that blood sugar starts to drop a little bit.” – Jordan (22:12)
• Consistency matters more than intensity; even small, daily movements help (“Stand up during work, walk around, stretch while watching TV, use stairs, or do ‘soleus pushups’ at your desk.” – 27:25, 27:39)
• “Having accountability is really important, too”—tell someone your goals or use public commitments for motivation. (31:27)
• Real talk: Everyone, even people who dislike exercise or struggle to find time, can fit in some movement with creativity.

c. Improving Sleep Quality (33:04–40:24)

• Sleep is a period for physical repair and hormone regulation; poor sleep increases cortisol, dysregulates hunger hormones (ghrelin, leptin), increases cravings, and creates a vicious cycle.
• "Ghrelin is the hunger signaling hormone… leptin's that satiety or I'm full hormone. If you're getting poor sleep, ghrelin increases and leptin decreases." – Jordan (11:29)
• Routines help—same bedtime and wake time, minimized caffeine, calming pre-sleep rituals (reading, chamomile tea, decreased screens).
• Technology tip: Biosensing rings/watches (e.g., Oura) can help track sleep and inform adjustments. (34:14)
• “If you sleep well when the sun’s down, then you can pack more into your life while the sun is up and you’re going to improve your overall health.” – Scott (40:06)
• Candid conversation about intimacy and unwinding as elements of a healthy sleep routine.

d. Nutrition & Processed Foods (40:24–52:26)

• You can have “good-looking” blood sugars on a poor diet, but health is broader than glucose numbers.
• Minimize ultra-processed foods (fast foods, frozen meals, packaged snacks) that contribute to insulin resistance, trans fats, and exposure to unhealthy seed oils.
• “One of [those] oils was developed as a lubricant… machine grease turned into food.” – Scott (41:42)
• Limit high omega-6/low omega-3 refined oils; prefer whole sources (nuts/seeds) or cold-pressed options (olive oil, coconut oil).
• Vitamin E and other antioxidants can help counter some processed food effects.
• “I truly believe that if people want to eat Twinkies and hot dogs and hamburgers all day long, they should be able to, but they should also have the information to know what potential consequences could be coming their way.” – Jordan (46:34)
• The “use as much insulin as you need” philosophy comes first; nutrition is the next layer in holistic diabetes care.

e. Sunlight/Natural Light Exposure (54:47–56:58)

• Sunlight helps your body make Vitamin D, which is linked to better insulin sensitivity and possibly lower risk for type 1 diabetes.
• “Getting outside… helps balance your circadian rhythm. Blue lights from screens can mess that up.” – Jordan (55:19)
• Even if you live in less sunny climates, going outdoors still benefits mood, circadian regulation, and usually increases activity.
• If stuck inside, blue-light blocking glasses are an option; orange tints block more than yellow.
• “Just get outside—if you’re getting outside consistently, there’s a high likelihood you’re also increasing your activity.” – Jordan (54:47)

Notable Quotes & Memorable Moments

• “You are more than a number… Your health is not just a glucose number. You have to look at it holistically.” – Jordan (19:12)
• “Type 1 diabetes, because you can get in trouble so quickly, it forces you to pay attention to it. And maybe that’s valuable for the rest of your life.” – Scott (20:18)
• “With a lot of these things, you do have to take some self-responsibility… You either come to terms with that and do what you can or you're going to be constantly blaming people and not doing well.” – Jordan (26:29)
• (On the order of advice) “I would rather you be in a world where you have two choices about your health—your blood sugars/variability and your nutrition. I would rather one of them be good than neither of them be good.” – Scott (50:07)
• “It’s not me, it’s not a bait and switch for me—I’m totally going to have a Dorito this weekend. I just want everyone to know it.” – Scott (50:48)

The episode is candid, accessible, supportive, and realistic, balancing medical insights with empathetic, firsthand understanding of diabetes life. Both host and guest acknowledge real-life obstacles and emotional hurdles, repeatedly affirming listeners' agency and the value of incremental, attainable changes. The interplay of practical tips and relatable analogies (“bucket with holes,” “GLUT taxi cabs,” “shoveling snow from your door”) make the science memorable and actionable.

Bottom Line:
Improving insulin sensitivity is about more than just taking less insulin—it's taking care of your whole self. Stress management, movement, sleep, nutrition, and seeing the sun intertwine to create a bigger, holistically healthier picture for people with (and without) diabetes.
