Conditions

Insulin resistance Insulin resistance is the engine behind prediabetes, type 2 diabetes and much of metabolic syndrome. It is also one of the most responsive conditions to changes in weight and activity.
Metabolic syndrome Metabolic syndrome is not a disease but a pattern — five measurements that tend to travel together because they share a cause. Having three of them roughly doubles cardiovascular risk.
Prediabetes Prediabetes is the stage where glucose is already too high but the pancreas is still keeping up. It is a warning with a clear response — and the window in which the most can be done.

Symptoms

Signs of insulin resistance Because the pancreas compensates for years, insulin resistance shows up in indirect ways long before a glucose test turns abnormal. These are the signals worth noticing.

Health guides

Foods that affect blood sugar The glucose response to a meal depends less on any single "good" or "bad" food than on carbohydrate amount, how processed it is, and what it is eaten with. Here is how the pieces fit.

Ingredients

What the evidence says about ingredients commonly used in this area.

Berberine Berberine is the best-studied plant compound for blood glucose, with dozens of trials behind it — most of them small, short and from a single country. Here is what that evidence does and does not support.
Chromium Chromium is one of the most common ingredients in blood sugar supplements and one of the most contested. Trials disagree, and the reasons why matter more than the headline.
Gymnema sylvestre Gymnema is the "sugar destroyer" of Ayurvedic tradition, and it does genuinely block the taste of sweetness on the tongue. Whether it does anything for blood sugar in the body is a much weaker story.
