That said, weight gain and obesity are caused by
hormonal imbalances. Out of all hormones human body produces, the only ones that passed the weight
gain causality test ( if we inject the hormone into people, they must gain weight) are INSULIN and CORTISOL.
The key to losing weight and get your metabolism to function properly is to lower the insulin and cortisol hormones.
Lowering insulin is done only by not eating refined carbs.
