It is also all about the types of foods you are consuming rather than the ones you should be cutting out which is why coffee is also another beverage allowed for slimmers on the diet.
Matcha can also be added to foods to disguise the taste and you can add it to baked goods, smoothies as well as mixing it in with porridge or granola.
