We need to talk about the biggest mistake people make when checking for diabetes. Millions of people are walking around with a false sense of security because they are misreading their lab results.
So how would you know if you are at risk? If you have a first-degree relative with diabetes or you have risk factors – meaning you’re obese, you have decreased activity, you have very high sugar intake, or high calorie and carb intake, or you have otherwise had symptoms – then you need to get checked out.
The idea is simple: if you intervene early and often, you protect your metabolic future. But if you’re relying on the standard A1C test to give you the all-clear, you might be looking at a mirror instead of a map.
The A1C Illusion: Sensitivity and Specificity
Let’s look at what the clinical data actually tells us about metabolic testing. It is entirely possible for a patient to present with an elevated hemoglobin A1C over a three-month period, but not actually be diabetic.
How does that happen?
It comes down to the science of testing – specifically, sensitivity and specificity. While the hemoglobin A1C indicates that you were exposed to high blood sugar, it doesn’t tell you long-term if you will continue to have it. It’s looking in the rearview mirror, not at the road ahead.
Instead, you should use fasting sugars and a glucose performance challenge as your true diagnostic tools. Then, you use hemoglobin A1c to follow up once you know a patient has diabetes to see exactly how good their control is.
The Truth About Weight Loss Drugs
This brings me to another major misunderstanding in metabolic health right now: the current craze around weight-loss shots.
It’s a fascinating piece of medical history that these GLP-1 peptides were actually developed as antihyperglycemics and anti-diabetic drugs over 20 years ago. In fact, the very first GLP-1 receptor agonist, exenatide, was approved by the FDA in 2005 strictly for the management of Type 2 diabetes. It wasn’t until 2014, nearly a decade later, that the FDA approved the first GLP-1 specifically for chronic weight management.(https://innovativerxstrategies.com/rx-history-glp1s/) The massive weight loss making headlines today? That was originally just a highly documented side effect in those early diabetes clinical trials.
This creates a crucial medical debate: Is it the weight loss and the fact that you’re simply eating less that leads to improvement in your diabetes, or is it the drug itself?
Biologically, it has to be the former, not the latter. Meaning that if you aren’t eating the same volume of food, and what you do eat is in good relationship to what your body actually needs, then obviously the metabolic improvement is going to be there.
Don’t Eat Your Way Out of It
Because the real magic is in the food reduction, you have to be incredibly careful.
The protocol I always propose if people go on GLP-1s is to stay high protein, low carb, and frankly, don’t eat a lot of carbs at all.
Why is the diet so strict even when you are on powerful medication? Because the harsh reality is that you can actually eat your way right out of the drug’s benefits. If you continue to flood your body with sugar and excess carbs, no peptide in the world is going to save your metabolism.
At the end of the day, whether we are talking about accurate diagnostic testing or managing medications, your daily lifestyle is the foundation. Intervene early, test correctly, and eat in a way that respects what your body actually needs.
