Insulin

What is it?

Insulin is secreted by the pancreas and used to digest the carbohydrates in food. The pancreas secretes insulin in response to carbohydrates being consumed. It then transports glucose – a simple sugar made from the digested carbohydrates – from the food to the muscles to be used for energy.

Is it out of whack?

If you have trouble losing weight, despite eating well and training hard, you may have a condition called insulin resistance, says Buntic. “In insulin resistance, the hormone insulin does not function as it should. The muscle cells build up a resistance to insulin, so the body produces more and more in an attempt to maintain the transport of glucose to the cells for energy.

“As insulin works to prevent fat being burnt to preserve muscle and fat mass, high levels of insulin can result in a situation where fat is stored rather than burnt, leading to difficulty in losing and maintaining weight.” If left unmanaged, this condition is likely to result in type 2 diabetes.

Quick fix: Insulin resistance can be managed with a low-GI eating plan and exercise including cardio and resistance training.
