Quit fighting it
If being in shape is part of your job, you’re used to thinking about what you can and can’t eat most of every day. The rest of us would rather get on with our lives and enjoy our dinner. We just don’t want to be fat.
Unless you just can’t bear to give up your microwave meal solutions, you can eat great food and get to your ideal weight:
- Without radical changes.
- Without feeling guilty every time you indulge.
- And without ever counting a calorie or weighing a portion.

Seems like a simple question, right? But when you’re talking about observational studies what they’re really asking is, “Why did that happen?” And that’s much harder.
What is an “observational study”?
When researchers look at something that happened without their input and analyze it, they’re observing something. This is different from a “randomized controlled trial” [RCT] where they design and conduct an experiment, knowing in advance what they’re going to be looking for.
What observational studies are great at is finding interesting and unexpected patterns in really large populations. For instance they might find that people with a certain gene are more likely to have a particular disease. Some of these patterns aren’t even noticeable until you’re looking at a really large group of people, and do you have any idea what it would cost to do a 20-year experiment with a million subjects?
What they’re not good at is proving why those patterns exist. And by “not good” I mean they can not ever prove the “why”.
Quick example: Where there’s smoke there’s fire. Did I just prove smoke causes fire?
Of course not, we all know fire causes smoke.
How about this one: Where there’s obesity there’s diabetes. Did I prove obesity causes diabetes? Or maybe diabetes causes obesity? Or is there something else — like eating a ton of sugar — that causes both obesity and diabetes?
Observational studies are useful for finding good questions. Then you need to do an RCT to answer the questions.
