We are big fans of coffee. We dig its flavor, its aroma, its health benefits, its feel-good buzz. We also know it’s easy to overdo, particularly when we’re rushed, stressed and depleted — which is precisely when all that caffeine is most apt to do us biochemical harm.
In this week’s episode of The Living Experiment, we look at both the upsides and downsides of coffee, explaining how it affects both your body and brain from the moment you take a sip.
We suggest ways to fine tune your coffee selection and habits, and offer our thoughts on the pros and cons of the burgeoning “butter coffee” trend. Finally, we present some experiments to help you make more conscious coffee decisions in your own life.

This Week’s Experiments
Take a three-week break from coffee and all caffeine to assess your relationship with it and its effect on you.
- Habitually consuming caffeine desensitizes you to its effects.
- For athletes looking for a performance boost, try reintroducing caffeine shortly before competition to get its full cognitive and physiological performance-enhancing effects.
- Evaluate how obligated you are to add a sweetener or fat source to your coffee. If you don’t like it without those additives, either you aren’t drinking good coffee, it’s not prepared well, or you don’t actually like coffee as much as you like your coffee condiments.
1) The next time you go into a coffee shop, order a “small,” not a grandé, venti or super-jumbo-big-gulp.
- Put your attention on the experience of consciously tasting and savoring that small-size cup (and notice how few people order a “small” anything anymore).
- Avoid adulterating your coffee with all sorts of added flavors (caramel shots, etc.).
- If you like having “cream” in your coffee, have real cream (preferably heavy vs. half-and-half); pass on the fat-free, skim or low-fat milk, and bypass the weird chemical substitutes.
- You probably won’t see heavy cream as an option unless you ask; many places stock it for whipping cream, and don’t put it out for customer use unless requested.
2) Experiment with different ratios of cream to coffee.
- Try adding a little more fat than you normally would, and then cutting back on sugar (if you normally add it). See how it impacts your enjoyment and satiety.
- Choose better coffee — better sourced, better roasted or better prepared. It may reduce your desire to add sweeteners and flavors.
