Our tea and coffee are not specifically designed to suppress appetite, but caffeine can suppress appetite for some people. Our teas and coffees contain natural caffeine. If you are fasting and can drink caffeine during your fast, you'll be just fine drinking our tea or coffee. There are no calories, fat, sugars or carbs in any of our beverages except for Mocha coffee, which contains a small amount of calories and carbs from the raw cacao in it.
