When we consume food, glucose enters our bloodstream and triggers insulin to be released by the pancreas. Insulin helps blood glucose enter the cells, where it is used as a source of energy. Any extra glucose is stored in the liver and in muscles.
Stored glucose in muscles is used during periods of intense physical activity, while that in the liver is used during periods of less intense activity. Glucose is also stored as triglycerides in our fat cells. This store is called upon during periods of prolonged fasting, and weight loss begins once this store of triglycerides in fat cells is tapped into.
High levels of blood glucose result in insulin constantly being released in the body, which then stops tapping into fat cells to release energy. This makes it hard to lose weight. At some point, constantly high insulin levels lead to insulin resistance. This inhibits glucose from being utilised by the body to generate energy. Instead, most of it gets stored in fat cells, leading to weight gain.
By wearing a continuous glucose monitor (CGMS) you will gain vital insight into this process. Because it tracks your glucose levels on a continuous basis, it provides real time data on your blood glucose levels from the foods you consume and the exercise you do. Avoiding the foods that cause blood glucose spikes gives your body a fat-burning advantage, resulting in weight loss.
