Notably, black coffee does not promote spikes in blood glucose and insulin levels that will disrupt the fat-burning benefits of your fast. This may be why intermittent-fasting research protocols often allow for black coffee to be consumed during the fasting window. No, you should avoid drinking coffee while fasting for bloodwork unless your doctor permits it. Bloodwork refers to laboratory tests that analyze components in your blood, such as glucose, cholesterol, and hormones, to get a baseline reading of your health. The main confusion about coffee and blood tests is believing fasting only means avoiding calories. For instance, a 2010 study in Diabetes Care by endocrinologist Rupali Deopurkar, M.D., Ph.D., found that drinking black coffee before a blood test did not affect fasting triglyceride or glucose levels in a small trial.
Intermittent Fasting
Some studies suggest drinking coffee might actually increase blood glucose levels and prolong the duration of elevated blood sugars short term (22). Yet, others found coffee could have a positive effect on glucose metabolism long term (23). Although coffee alone isn’t likely to negatively affect your fast, adding calorie-containing ingredients could. “Loading your cup with high-calorie additives like cream, milk, and sugar disrupts your fast and might limit the benefits of an IF protocol,” says Fernando.

The only time when coffee is more kryptonite than sidekick to your fast is if you load it with creamers, sweeteners, and other additives — or if you overdo it on the caffeine. Coffee shops tend to use a “cream” that’s really a mix of milk and cream, which means even a tiny splash may contain more protein and carbs than you bargained for and break your fast. There’s also more of a risk of hidden sugar, like in the form of soy, rice, and nut milk (like almond milk) alternatives.

People with underlying gallstones can get symptomatic with ingestion of coffee.”
Additionally, the caffeine and other bioactive, plant-based compounds found in coffee reportedly act on pathways in the body that help regulate hunger. Coffee may also have an impact on appetite, though the research on this is mixed. A scientific review published in 2017 suggests that ingesting caffeine 30 minutes to four hours before a meal may suppress calorie intake, though researchers emphasize that more studies are needed. Another study found that caffeine’s impact on appetite is context dependent, meaning it may increase or decrease appetite. And a 2018 study found caffeine has a “weak effect” on calorie intake and is not an effective appetite suppressant.
What about coffee during times when you usually eat?
You can think of the fasting period as a time for your body to go into “cellular housekeeping6” mode. Between improving brain function, reducing inflammation, and lowering metabolic risk, the evidence for including coffee in your fasting routine appears to be pretty positive — in moderate amounts. When you fast, the goal is to keep insulin levels low, encouraging your body to burn stored fat for energy instead of storing new energy from the food you eat. For non-coffee drinkers, this can mean grabbing an alternative that gives you a boost, such as an energy drink. However, with increased scrutiny on energy drinks and their potential health effects, many are asking, “Will energy drinks make me gain weight?
However, focusing only on these markers overlooks the main reason to avoid coffee before blood test, which is the caffeine itself. Adding artificial sweeteners like aspartame or acesulfame potassium to coffee while fasting should be avoided due to their potential to stimulate insulin release despite being low in calories. Research further suggests that artificial sweeteners such as aspartame or sucralose may disrupt the gut microbiota and interfere with metabolic processes, potentially undermining the metabolic benefits of fasting. Consumption of artificial sugars can also perpetuate cravings for sweet foods, making it harder to adhere to fasting protocols and maintain stable blood sugar levels.
