(This study is from 2008, before Intermittent fasting became popular)
The 12 week study had 27 participants exercise for 45 minutes(only a few actually went to a gym, most was brisk walking) followed by a 12-14h mini fast, 3-5 days a week. There were no dietary restrictions placed on the subjects, only that they had to fast for 12-14h. The average weight loss was 7.4kg over the 12 weeks, with 7% reduction in body fat. Also noted was a 25% reduction in fasting insulin levels. Although this was a small study, it does have good implications for intermittent fasting which is gaining popularity. The authors attribute the increase in fatty acid oxidation to up regulation of AMPK and PGC-1alpha, as well as post exercise ketosis. I don't know if I could go 12h without eating 3-5 days a week, but this study shows that it's a good strategy for losing fat, specifically. It seems muscle was preserved, just like In a Keto diet.
