Why is it so hard to lose weight?
When you gain weight, your hormones change in ways that hinder your weight loss efforts. Hormones such as insulin, cortisol, leptin, grehlin and thyroid hormones all play a role in weight
For example, patients who are overweight may be leptin resistant. When you’re resistant to leptin, you can carry extra weight, yet your brain thinks you’re low on energy reserves. As a result, you feel hungrier throughout the day and eat more than you usually would.
