Intermittent fasting is a trending program usually associated with the ketogenic diet. It involves the avoidance of meals for longer periods per day and consuming forbidden ones defeats its purpose. Since coffee is one of the most consumed drinks in the world, many are wondering if drinking it won’t ruin the promised benefits of the fasting program.

What Is Intermittent Fasting?

Intermittent fasting is a dieting pattern that improves metabolic health and extends lifespan, according to Healthline. When doing this program, you may choose a particular eating schedule that fits your lifestyle. You may choose not to consume food and certain liquids for 16 hours per day, two days per week, 24 hours once or twice a week, fast during the day and eat a huge meal during the night, fast every other day or skip meals without following a structured intermittent fasting plan.

During the times of no consumption, you are only allowed to consume very low-calorie to zero-calorie beverages since you fast in order to not break the cycle.

Intermittent Fasting and Coffee

New research published in the US National Library of Medicine claimed that drinking black coffee does not break your fast. It does not cause a significant metabolic change and it even suppresses your appetite. Thus, drinking black coffee while you fast helps you withstand the long periods of no food consumption. The appetite suppression benefit of black coffee, however, remains scientifically unproven.

When you are intermittent fasting, your body generates ketones which are linked to improving brain function. The caffeine content in coffee also promotes ketone production.

Considerations

There are several forms of coffee in the market which, when consumed, reduce fasting benefits. If the ones you drink contain additives such as sugar and milk, the beverage then defeats your fast as these components trigger metabolic changes. It is best to steer clear of cappuccinos, lattes and other high-calorie or sweetened coffee drinks during your fasting periods.

Pure black coffee with a teaspoon or five milliliters of heavy cream or coconut oil does not alter your blood sugar levels or increase your total calorie intake. So this is the best coffee to consume while fasting.
