it was a cohort study, they had over 200k participants who filled out the study form, so even through their was a low effect size the confidence can be quite high.
I know the study isn't anything to get excited about, but preventing weight gain is itself a worthy goal. It's so easy for the weight to creep up on you.
If it's a significant amount less or "ungained" weight, then absolutely - I know the creeping weight well. But in this case, any semi-decent dump is going to outweigh the whole thing. It's the kind of weight difference you'd shrug off in one day, let alone over 1400+ days.
So they based this study on people who exclusively drink instant coffee?
I mean, not to be that guy, but does anyone actually like instant coffee?
How would the results differ in a real world scenario? You know, with real coffee?
I do not even care if you prefer drip-filtered or cappuccino or soy latte with tripple choc shot and papaya slices, but fucking instant coffee?
First, the findings represent an association, not causation. This means the study does not prove that coffee intake is the true reason for the weight change. Rather, it shows the two changes were observed together over time.
Coffee makes me incredibly hungry (any caffeine does). This would backfire on me soooooo bad.
I have to wonder if an extra cup of any liquid per day would help avoid weight gain. You hear so much about people misinterpreting thirst as hunger - they eat instead of drinking.
