Insulin resistance is not always a sign that something is wrong. During a very low-carbohydrate diet, the body can temporarily reduce glucose uptake in certain tissues to preserve glucose for cells that depend on it, such as red blood cells. This clip explains the concept of physiological insulin resistance, why it differs from metabolic disease, and how the body adapts when carbohydrate intake stays very low.

Taking 200 mg of thiamine doesn’t necessarily mean your body gets 200 mg. Standard forms like thiamine hydrochloride rely on transport proteins in the gut, cells, and brain that can become saturated. This clip explains why that creates a bottleneck in B1 absorption and why increasing the dose doesn’t always translate into the same increase in thiamine reaching your tissues.

Your cells need energy to repair, communicate, and carry out the processes that keep you functioning. At the center of that energy production are the mitochondria, which convert nutrients from food into usable cellular energy. This clip explains why impaired mitochondrial function is seen across many chronic diseases and why understanding what prevents cells from producing energy properly can be an important piece of understanding chronic illness.
