This means no added sugar including white, brown, and coconut; natural sweeteners like maple syrup, honey, and agave; and artificial sweeteners. Sugar elevates insulin levels, which block the hormone leptin and overload your dopamine receptors, which leads to insatiable cravings. This is why you eat cookie after cookie and still want more — eating sugar makes you crave it. In order to break this cycle, you need to stop eating sugar, and the cravings will disappear.
Fresh fruit is allowed since the fructose in fruit doesn't affect your brain the way refined sugar does and because fruit also contains fibre, which slows down digestion. Dried fruit, fruit juice, and blended fruit (like smoothies and frozen banana ice cream) are not allowed since the sugar is more concentrated. Remember: we want to keep dopamine receptors quiet.
