Insulin's job

Insulin functions primarily to store fat and regulate energy levels in the bloodstream, operating continuously to prevent excess fat from circulating. As individuals gain weight, their fat cells can become overfilled, prompting insulin production to rise in an effort to manage this excess fat by keeping it stored. High levels of insulin indicate a body struggling with fat storage, particularly in those with abdominal fat. In contrast, individuals with lower body fat may have significantly lower fasting insulin levels. This highlights the necessity of insulin's constant presence to prevent energy overload in the bloodstream, maintaining balance in the body's metabolic processes.
