  • Is coffee ruining my fasting

    Just started IF for 16 hours 4 or 5 days ago. I've been continuing to have a couple of cups of coffee with a little cream or an ounce of almond milk. Will that break the fast? Am I wasting my time fasting if I continue to drink my coffee in the AM

    No not really. The almond milk yes because it has carbs. Try coconut oil in the coffee, it's good.

      coffee won't, but adding something with calories basically does. by definition.

      if you're interested in maintaining autophagy, then sticking to fat without protein or carbs will still work during a fast. if you're interested in fasting for body composition, you definitely need to keep the calories very low, but it's probably fine to have the cream in the coffee.

      but a fast is a period without food - calories. and cream or almond milk both have calories, ergo, you consume them = you're not fasting.

        I think it really depends on what you define a fast as. A lot of people define it as lack of calories for your body to work with, so coffee is fine. A few people define it as a time to let the digestive system/liver rest, in which case coffee would break your fast. Up to your goals.

          Fasting basically consists of getting the majority of your calories from endogenous, rather than exogenous sources. How do we define "majority"? That depends, but the spectrum would have to run from 51% to the hardliner 100%. I would say a reasonable threshold would be 80% to 90%. For the sake of argument, if your daily maintenance caloric intake is 2000 cal, then you have about 200 calories to play with if you accept that a fast consists of getting 90% of your caloric needs met from endogenous sources. Two ounces of heavy cream would put you at roughly 200 calories. This is heavy cream, mind you, you could have more if you used light cream, and even more if you prefer half and half.

          Bottom line, enjoy your coffee and cream and try not to obsess about it.

            Drink it black! High-quality black coffee gives me heaps of energy. YMMV, though.

                Thanks all. I'm not doing for any cleansing. My reasons for doing it are: 1. I want to lose that last 3-4 percent body fat and 2. It saves a lot of time to not have to cook until 2 pm.

                I just wanted to make sure that having 100 calories or so wasn't going to set up some metabolic process and drastically affect the fat loss

                  I was curious also. I have read BP dude's views. And I dont care if it is called fasting, so long as I get the results. My BP coffee is what gets me by. I just have one. And when I go for a 24, I will have another for lunch. I am shooting for 48 now, so I was curious to the replies and particularly the explanation of an acceptable range of exogenous calories.

                  I have done it long enough now, I could probably make do with just half & half. Tried it once and I survived. I see lots of half&half in my future over the next 2 days since I limit the BP coffee.

                    Hello, I'm new to this forum, found this post through a Google search about coffee and fasting. I can see it's old, so, sorry for the thread necrophilia, lol.
                    Anyway, the reason I was reading about this, is that yesterday, I listened to the Joe Rogan Experience, it was his second interview with Dr. Rhonda Patrick. Episode 901 In the last twenty minutes, they spoke a lot about time restricted feeding/intermittent fasting, and Dr. Patrick claimed that when you drink coffee (even black), you break your fast. Essentially, the idea was, that you will still experience heightened energy (but, only due to the caffeine), weight loss and autophagy, but that there are many other benefits to fasting, that you lose when you consume anything other than water.

                    She got into the reasoning, but it was too complex for my simple mind. Anyone else listen to this podcast/interview? Any thoughts on it?

                      Autophagy is probably the most important function of fasting from a health standpoint. Clearing brain fog and heightened awareness certainly is a major benefit. Weight loss is a 2-edged sword, because ending the fast will result in the body rebooting its fat stores. Those are 3 of the main reasons for attempting a fast; so purists who want water only can do so; but the rest of us can have those benefits w/o being quite so strict. Please note there is a huge difference between one cup of creamed coffee, and a couple pots of coffee daily.

                            All pretty much on target, love that "thread necrophilia!" Variables seem to be how hard core, how anal retentive the definition and follow through is. Mainly, are we talking any calories at all, or maintaining autophagy.

                            Six cups of coffee, to pick a number, has 1.7 calories, mostly from protein. A tablespoon of cream has 30, but almost all from fat, which does not trigger insulin.

                            My medical provider has no issue with fasting blood tests if all I've had is black coffee.

                            My perspective is that if your goal is autophagy, black coffee is just fine. And remains fine with just fat added.
