Best of 2015: Why I quit coffee

Why I Quit Coffee

Yep, a month ago I quit drinking coffee, cold turkey, from 8 cups a day.


I haven’t touched coffee yet, instead I’m sticking to naturally caffeine-free tea.

As I described in the post, quitting was quite a miserable experience during the first week. Then I started to feel better. But it’s not until the last week or so that I feel all the motivation is back – I felt slow and unmotivated for several weeks.

As coffee has some acute insulin- and glucose-raising effects I was speculating if quitting would result in minor weight loss (not that I needed it). That’s not what happened. Instead I felt distinctly hungrier, and may have gained a few pounds over the holidays (there could be other possible explanations, considering the timing).

In hindsight it seems fairly obvious: caffeine is a stimulant, and stimulants usually suppress hunger and help weight loss.

I’m still happy with the decision to quit though. I feel calmer and more focused. I’m fully awake right away in the morning. And I love the feeling of not being actively addicted to caffeine.


As a bonus my blood pressure is down a bit more, averaging about 112/72. Caffeine raises blood pressure, being a stimulant, and quitting coffee lowers blood pressure. Low carb and intermittent fasting helps too.

    I quit coffee and was very sleepy all the time until I found green tea is making me awake! So no coffee, only green tea now))

    With the lowcarb lifestyle, we give up things that we know are actively damaging our health. (e.g. sugar, wheat, etc.) Life should be enjoyed, and some lowcarbers reward themselves with wine, with lite beer, or dark chocolate. It seems our humanity dictates that we want (or need) a taste-reward food or drink in order to enjoy life. This is what coffee is for me. Is the caffeine addictive? Without a doubt. However, the "experts" can't seem to decide if coffee is evil, or a wonderful healthy cup of antioxidants that will improve your health. So, until there is some really good reason to give up coffee, I'm going to continue my habit of 3-4 cups per day. It is one of life's simple pleasures and I "reward" myself each morning and throughout the day. I drink it black, no sugar, and it truly is a pleasurable experience. I admire your willingness to experiment Andreas...and I love your site and have learned much here. I'm going for the trial subscription and look forward to learning more. Keep up the fantastic work you are doing!

    Hi Steve,
    I am on the trial membership as well and just asked Dr. Eenfeldt what he does now since he helped me realize in one of his great videos I am overdoing the heavy whipping cream. I see here now that he has quit coffee. However, like you, since coffee can fit in with the LCHF lifestyle, I too intend to enjoy my daily java, just with much less HWC (Thanks Doc!).
    Though I have been doing LCHF for quite awhile, I have experienced it becoming less effective over the years. Having said that, I have learned many things from this site in a few short hours that help explain that, including "buying" into the "fake" foods to say the least. So I look forward to learning much more in the coming months as more is added to the site.
    Dr. Eenfeldt, this is a great site!

    Is coffee the issue, or is it caffeine. What about decaffeinated coffee?
  6. Peter Biörck Team Diet Doctor
    Caffeine is the issue. It triggers the stress hormone cortisol. If you are drinking a lot of coffee that could be a problem.

    Decaffeinated coffee do not have that problem, but personally I would recommend Rooibos tea instead :)

    I have chronically LOW blood pressure.
    I can’t drink water with himalayan salt only during my longer fasts; and during a regular low carb/keto day where I can comfortably skip breakfast, I would never be able to function without dizziness were it not for that initial cup of glorious (liver-protective) coffee in the morning.
