Struggle with weight? Biology and metabolism play a huge role.
Weight loss struggles are not just about overeating or not getting enough physical activity. Metabolic and cellular changes are harder to see and just as impactful in your efforts to shed extra pounds.
One of the invisible factors at play is insulin resistance, which is when your body’s cells don’t respond well to the hormone insulin, and therefore, can’t convert glucose from the food you eat into energy. Over time, insulin resistance causes your blood sugar levels to rise and that glucose in your blood is stored as fat – leading to, you guessed it, weight gain. It can also lead to type 2 diabetes and other chronic conditions if left untreated.
60% of medically overweight individuals in the US have evidence of an advanced form of insulin resistance, which means that the food they eat is not being properly metabolized at a cellular level. See the study
From this perspective, the difficulty resisting hunger that so many dieters have isn’t a sign of poor discipline, but rather a biological problem involving how our bodies distribute the calories we consume.
