  1. Just a little bit: caffeine by it self can cause the release of glucose by the liver. It’s not a large increase in blood glucose, but it is real.

  2. No, black coffee is safe for fasting.
    As is unsweetened tea. Both also have the benefit of the caffeine content “tricking” your mind into thinking your hunger has been satiated.
    I’m not a fan of either, so if I want caffeine while fasting I have to resort to zero calorie energy drinks sweetened with sugar alcohols like Erythritol. Sugar alcohols (and other zero calorie sweeteners) are not absorbed into the blood stream and do not raise bloo…

  3. This is just me thinking out loud as a physician and avid consumer of caffeine. Coffee activates the sympathetic nervous system, commonly referred to as the “fight or flight” response in the body. A big part of this is the release of epinephrine. This is what causes the increased mental focus, increased heart rate and dilated pupils associated with caffeine. Epinephrine also causes an increase in blood glucose levels by decreasing the sensitivity to insulin. This makes sense, because we need extra sugar to rev up all our systems in fight or flight. Therefore, I think that coffee should increase blood glucose levels. Like anything else, this is probably fine in the short term, but may potentially affect our overall health if it is a chronic exposure over decades.

  4. No, unless you wash it down with a few donuts! When i first developed diabetes i bought some calorie books and got very depressed! Now i have a good feel about how many calories i am taking in so not as essential. There are some good apps for this now and also good apps for finding calorie count for restaurants – OMG – talk about depressing……

  5. For a healthy person: NO. Coffee has no natural sugars so it will not affect any of the bodily functions that influence blood sugar. Because it is a stimulant, if you drink coffee with food, it may have an effect on how fast the body absorbs the food.
    How Does Caffeine Affect Your Blood Sugar?
    A growing body of research suggests people with type 2 diabetes react to caffeine differently. It can raise blood sugar and insulin levels for those with the disease.
    One study looked at people with type 2 diabetes who took a 250-milligram caffeine pill at breakfast and another at lunchtime. That’s about the same amount as drinking two cups of coffee with each meal. The result: Their blood sugar was 8% higher than on days when they didn’t have caffeine. Their reading also jumped by more after each meal.
    That’s because caffeine can affect how your body responds to insulin , the hormone that allows sugar to enter your cells and get changed into energy.

  6. If you have to have a blood test that is a fasting one for 12 hours you are allowed black unsweetened tea/coffee.
    I have always done this as the tests are usually for Cholesterol/sugar and it has never interfered with the test.
    So no it will not affect the blood test in my experience.

  7. It does not effect the blood sugar level directly. But what happens is that, from my point of view of homoeopathy, few remedies have direct relationship with the coffee. So when we take coffee, it either suppresses or favours the infection that might be hidden in the body. This effect of coffee in turn influences the functioning of the gland PANCREAS. Once the Pancreas functioning is influenced, the release of insulin is effected and in turn this effects the blood sugar level.
    It would be worth to note that Homeopathy is the soft science of balancing the vital l…
