If you’re over 40, eating the way you always have, and weight loss has stalled, insulin resistance may be part of the story — even when your fasting glucose and A1C look normal. Here’s what changes after 40, and the exercise and protein strategies the research actually supports.

After 40, many people lose muscle gradually. Muscle is where most of your blood sugar goes after a meal, so as that “glucose tank” shrinks, your body may make more insulin to compensate — and insulin is a storage hormone that makes stored fat harder to release. The good news: muscle responds to training at any age.
In this video you’ll learn:
• Three signs of insulin resistance you can check in the mirror (and why none of them diagnose anything on their own)
• Why muscle is your body’s biggest glucose sink — and what happens as it shrinks
• Why a 10-minute walk after meals may matter more than when you exercise
• Walking vs. lifting weights: why you need both
• How much protein to aim for at each meal, with real food examples
• What the research shows about creatine and strength training in adults over 50
