What If Tonight’s Dinner Could Lower Tomorrow Morning’s Blood Sugar?
from The Habit Healers · host Laurie Marbas, MD, MBA
If your fasting blood sugar keeps coming in higher than you expect, the answer may not be sitting on your breakfast plate. In this episode I break down the second meal effect, the research showing that what you eat at one meal measurably changes how your body handles the next one, sometimes hours later, sometimes the following morning.I’m Dr. Laurie Marbas, and on The Habit Healers Podcast I like to take the science apart and hand it back in a form you can use tonight. We look at how lentils, beans, and whole barley kernels feed your gut bacteria overnight, how those bacteria make short chain fatty acids that set up better glucose control the next day, and why a food’s structure matters more than the fiber number on the label. We also cover what this means if you live with type 2 diabetes, and why two people can eat the same dinner and wake up with very different numbers.What you’ll learn:* What the second meal effect is and why it lowers blood sugar hours later* Why intact barley kernels and lentils improve fasting glucose while the same grains ground into flour do not* How gut bacteria and short chain fatty acids drive overnight glucose control* Why skipping meals weakens the priming effect on your next meal* How the second meal effect works in people with type 2 diabetes* A simple half cup habit you can start at dinner tonightDr. Marbas Substack Article: https://drlauriemarbas.substack.com/p/what-if-tonights-dinner-could-lowerCheck out the Habit Healers Community: https://www.skool.com/habithealers/about Get full access to The Habit Healers at drlauriemarbas.substack.com/subscribe
