Two Fuel Tanks

The human body uses two main sources of fuel: glucose and fat. Glucose is a type of sugar that comes from carbohydrates found in food, like fruits, vegetables, and grains. It's the main energy source for our cells, including those in the brain and muscles. When we eat food, our body turns it into glucose and sends it into the bloodstream to be used by our cells for energy or stored for later use. Fat is stored in our body in adipose tissue and is used as a secondary source of energy. When glucose levels are low, like during exercise or when we haven't eaten in a while, the body will start to break down fat stores and turn them into molecules called fatty acids. These fatty acids can then be used by the cells for energy.

When insulin levels are high in the body, it signals to the body to store glucose as fat rather than using it for energy. When insulin levels are low, such as during exercise or fasting, the body is able to access stored fat and use it as an energy source. High levels of insulin can also inhibit the release of fat from the adipose tissue, which makes it harder for the body to access stored fat for energy. Insulin resistance, which is commonly seen in conditions such as obesity, type 2 diabetes, and metabolic syndrome, also plays a role in fat storage and energy metabolism. When the body becomes insulin resistant, it requires higher levels of insulin to transport glucose into the cells, resulting in lower energy levels and strong cravings.
