We’ve all heard of Insulin and with 90% of diabetics diagnosed with Type II Diabetes, you probably know someone who has been diagnosed or worse you are dangerously close to the diagnosis yourself. Most people (if not all) have heard they need to exercise more and eat better. We all know this is easier said than done, especially with so much conflicting information swarming all around us.
Insulin isn’t the only culprit in the charade of sugar and an overall increase in body fat. Two other hormones, Leptin and Ghrelin, have their own role in this evil biological plan to get you fat and keep you there. Knowing how this works will help you break this vicious cycle.
Insulin inhibits glucose production (so there is not too much in your blood). Insulin resistance gives the liver the impression that blood glucose (sugar) is low. This triggers the release of glucose into the bloodstream in spite of the fact that it is already too high. This condition is due to chronically elevated blood glucose levels. Insulin sensitivity of the liver depends on the leptin sensitivity of the brain. So what is Leptin you ask…?
Leptin plays a major physiological role in the control of glucose metabolism (using glucose/sugar for energy).Leptin resistance impairs the brain’s ability to detect how much fat mass the body is carrying. In spite of high leptin levels, leptin resistance tricks the brain into thinking that energy stores are insufficient, which results in decreased energy expenditure and increased appetite. Yep, you read this right ‘Your brain wants you to eat more and do less!’
Ghrelin is a hormone that signals hunger to the brain. Sugar dampens this hormone and interferes with the normal transport and signaling of the hormone leptin which helps to produce the feeling of satiety. It also reduces dopamine signaling in the brain’s reward center thereby decreasing the pleasure derived from food and compelling one to consume more. In essence, food isn’t as fun as it once was which makes you want to eat more.
To sum it all up, sugar addiction and chronically elevated blood sugar levels put you at risk of developing insulin sensitivity, Type II Diabetes and weight gain. This creates a domino effect that directly affects your brain increasing your appetite and demotivating and depressing you. Now that you know why it’s so difficult for you to change your habits it’s up to YOU to break the cycle. You CAN fix this today with the obvious solution, force yourself to get up and make a change. Slowly change your eating habits and get outside and start exercising. If this feels overwhelming find a professional that can help guide your journey one step at a time.
