The good news, according to Weltman, is that high intensity — the level at which you feel the effort and can no longer hold a conversation — is different for each person.

Research shows the average American eats about 20 teaspoons of sugar daily, often hidden in processed foods, including “healthy” ones such as yogurt, frozen dinners, sauces, and salad dressings.
