Based on my own personal experience (and, to a lesser degree, some other sources I've read online), intermittent fasting (IF) leads to the opposite of obesity.

With a smaller eating window (e.g. less than or equal to 8 hours in a day), there is a greater likelihood that less food will be consumed. This relies on CICO (ie. calorie consumption being less than TDEE). I read the linked abstract but there was no mention of number of calories consumed by the test subjects; I estimate that this would be the most critical factor with regard to weight loss.

As far as the claimed likelihood for type 2 diabetes, it seems to run counter to everything I've read about IF. When a person restricts their eating to a smaller window of time, their body's insulin resistance decreases, thereby lowering the likelihood of developing type 2 diabetes.
