Well, the trick is that the confidence intervals overlap, and do so pretty heavily. So, while on average they may have lost more, their test group size was either quite small or had high variability such that it could come down to randomness that one group lost more than the other. At the end of the study they had 61 in calorie restricted and 57 in intermittent fasting. So, not huge groups. And looking at their confidence range knowing their numbers, it likely means on both sides multiple people lost 7kg on both sides. I didn't see a way to download that study to get the raw data, which would also be helpful, as I think it would also be useful to look at % body fat loss, etc.
