SuppVersity - Nutrition and Exercise Science for Everyone

ADF vs. continuous dieting in overweight/obese women: ADF marginally faster, about identically satiatin' but not per se 'superior' "When Weight Loss is Standardized (to 5%), Overweight / Obese Women are Neither Hungrier Nor More Satiated When Eatin' in an Alternate Day vs. Chronic Energy Deficit. Implications?" ⬅ that's the title of a #SuppVersity Facebook and Instagram post I was just about to publish yesterday to then decide: 'Hey, you've spent a lot of time to summarize the results of this study. Spend another 10 min (which became 1h) and you've got a short news item and hence a new article many of you may be (rightly) waiting for...'

They may have been published in "Obesity" and observed in people w/ weight problems, but the results of these three recent papers are still relevant for lean, metabolically healthy people, too. Even if you are already way beyond the stage, where "weight loss" is your main interest, I am pretty sure you will appreciate this selection of recent studies from obesity research all around the world. After all, some of the research may actually help you achieve your new goal which should be to lose body fat while keeping or even building lean mass. In today's research review I am going to discuss three papers that have recently been published in the International Journal of Obesity (after being available online since late 2017, btw). To generalize one could say that the papers deal with the effects of nutrient timing and your microbiome on the efficacy of your fat loss efforts.

It would be nice to see if this form of "long-term"-refeeds or diet-breaks works for leaner men as well.  You will remember that I've previously discussed the advantages of cycling your energy intake in both, classic intermittent fasting or alternative-day fasting contexts, as well as refeeds . Just like the protocol that was used in a recent study from the University of Tasmania  (Byrne 2017), all these diets belong to a category of diets that is characterized by what scientists call "intermittent energy restrictions". The latest RCT by Byrne et al. (2017), which has just been published ahead of print , took a slightly novel approach to energy cycling, though. Compared to IF and ADF, regimen, the energy intake in form of very long intervals (weeks vs. days or hours): more specifically, 8x2 weeks of dieting interspersed by 2 weeks on a maintenance diet. Despite these differences, the reasoning behind the study design was pretty much the same bodybuilde...

This is not the kind of refeed I would suggest - irrespective of how effective refeeds are using all of them to pig out to the extremes will be counter-productive. There are three purported benefits of "refeeding", i.e. having 1-2 days per week where you eat as much as you want, regularly, while you're dieting. The refeeds are supposed to (1) prevent your metabolism from shutting down to ensure continuous fat loss, (2) help maintain lean mass and (3) reduce the weight rebound when you return to an energy sufficient diet. Yes while the efficacy of this practice has been demonstrated before ( more ), previous studies did not have an appropriate control group that would allow us to say for sure whether dieting continuously wouldn't have yielded the same results.
