It can be a little confusing to understand what drinks maintain a fast; but here goes.
Fasting and ‘no snacking’ means avoiding all food and drinks which supply energy,as they excite release of insulin. When insulin is circulating, fat burning is prevented. Any drink that supplies energy, in the form ofsugar, fat or protein causes insulin release. The amount of insulin released varies depending on the macronutrient.
Water, black coffee, black tea, green tea, white tea and natural herbal teas do not supply energy and can be drunk during a fast or between meals.
Beware that packaged herbal teas can be deceptive and may have added sugar, such as dried fruit and other additives. So yes, to herbal teas, when fasting, but only those without sugar or other additives. Drinks must not contain any milk, honey, cream, sweeteners or sugar. Now that is the perfect world.
We are frequently asked if a lemon slice or root ginger in hot water breaks your fast. Commercial ginger and lemon teas are very likely to have added sugar, so they should be avoided. Technically, the answer is that a lemon slice and a piece of root ginger do break your fast, as there is a minuscule amount of energy in both drinks. But, it may be an option that you need to pursue.
Here are the things to consider: A large ice cube sized piece of ginger has 1g of carbs. This gives up 4 calories when our bodies digest it. But you aren’t eating the ginger, so the amount you get in your drink is much less than one gram of carbs. You could argue that this is insignificant in the scheme of things and then incorporate ginger tea into your fasting regime. A piece of ginger in hot water is clearly a better option than breaking your fast.
People also wonder about adding a slice of lemon to water and it is essentially the same argument as for ginger. The slice of lemon, if not squeezed, nor eaten supplies less than one gram of carbs.
You will be able to work out what works for you, and you may feel that you need the ginger or lemon slice, in hot water to help you along the way, during your fast.
