Stressful feelings are all part of life — that we all experience. Yet they trigger a release of adrenaline and cortisol — our body’s natural stress hormones. Aside from getting us ready to fight or flee, these hormones temporarily raise blood sugar levels, which, over time, may lead to greater hunger. Chronic stress can also interfere with digestion, sleep, and immune function. And stressful thoughts interfere with the more creative, resourceful, and logical parts of your brain that can help you problem-solve.

What you eat is more important than how much you exercise. Exercise is not the most important thing to focus on when you want to lose weight — although it has numerous other health benefits, including maintaining a healthy weight. As Dr. Roberts’ lab has proved, what you eat and how much you eat play a substantially greater role in determining whether you shed kilograms. But her research has gone much deeper, showing that different people lose weight more effectively with different foods. This realization allows us to create personalized weight-loss plans for individuals that work better than any one-size-fits-all advice.
