The ANUWELL Guide to Metabolic Health

Here is the part that surprises people. If you swallow glucose, your pancreas releases far more insulin than if the exact same glucose were delivered straight into a vein. The difference is a set of hormones your gut releases the moment food arrives, signals that tell the pancreas what is coming before blood sugar ever rises. Those gut signals can account for the majority of the insulin released after a meal. ^[5]

One of those hormones is glucagon-like peptide-1, or GLP-1. Your body has been making it your whole life. It helps time insulin release, slows the stomach, and tells the brain you are satisfied. Metabolic health is the name for how well this entire conversation is going: gut, pancreas, muscle, fat tissue, and brain, all responding to food in coordination.

Glucose is the sugar your body runs on. Most carbohydrates you eat end up as glucose in your blood within an hour or two.

Insulin is the hormone that moves glucose out of your blood and into cells, where it becomes energy now or storage for later. When insulin works well, blood sugar rises gently after a meal and settles within a few hours. You feel steady. When it works poorly, the swings get bigger, and energy, hunger, and mood swing with them.

Insulin resistance means your cells respond less to insulin's signal, so the pancreas compensates by making more. For years, sometimes a decade or longer, the extra insulin keeps blood sugar looking normal on a standard fasting glucose test. The strain is real, but invisible. ^[6]

This is why more than one in three American adults has prediabetes and more than eight in ten of them have no idea. ^[1] By the time fasting glucose looks abnormal, the process is well underway.

The practical implication: a normal glucose reading is not the same as good metabolic health. Fasting insulin, HbA1c, and triglycerides show strain earlier, which is exactly when it is easiest to reverse.

Many people describe constant, intrusive thoughts about food. There is now a name for it: food noise. It is a hormone signal turned up too loud, not a personality flaw.

In one well-known study, researchers followed people for a full year after they lost weight. Twelve months later, their ghrelin was still elevated, their fullness hormones were still suppressed, and they still reported more hunger than before the weight loss. ^[7] The body was actively defending its old weight, long after the diet ended.

That may sound discouraging, but it is actually clarifying. Regain after a diet is not a failure of effort. It is a predictable hormone response, and it is precisely the response modern treatment is designed to address. Keeping weight off is a physiological project, and physiological projects respond to the right tools.

Muscle is where most of your glucose goes. Under insulin's signal, roughly 80 percent of the glucose cleared from your blood is taken up by skeletal muscle. ^[2] More muscle, and more active muscle, means more capacity to handle the food you eat.

This is why muscle matters so much during weight loss. Some lean mass loss happens with any significant weight loss, whatever the method. ^[8] Protecting muscle protects the very tissue that keeps your metabolism working, and two things protect it reliably: adequate protein and resistance training. ^{[8, 9]}

GLP-1 medications are prescription-only and are not appropriate for everyone. They should not be used by people with a personal or family history of medullary thyroid carcinoma or Multiple Endocrine Neoplasia syndrome type 2, and they carry warnings including pancreatitis, gallbladder disease, and kidney injury with severe dehydration. Tell your provider about all conditions and medications, including diabetes medications, and about pregnancy or plans to become pregnant. Common side effects include nausea, vomiting, diarrhea, and constipation, most often when starting or increasing a dose. Seek medical care promptly for severe abdominal pain, persistent vomiting, or signs of an allergic reaction. Only use GLP-1 medications prescribed by a licensed physician and dispensed by a licensed pharmacy.
