    Well the burden of proof is on those making the claims of benefit but, I'll play.

    Thank you. Appreciate it.
    In two of these studies, there was significantly reduced insulin concentrations
    The most recent of these reviews (2014) found that intermittent fasting regimens demonstrated 3–8% reductions in body weight after 3–24 weeks in comparison to energy restriction, which demonstrated 4–14% reductions in weight after 6–24 weeks.
    Results from these intervention trials of modified fasting regimens suggest that these eating patterns result in weight loss, with modest and mixed effects on glucoregulatory markers, lipids and inflammatory markers.
    Another cross-over study compared the effect of consuming one afternoon meal per day for 8 weeks and reported 4.1% weight loss in comparison to an isocaloric diet consumed as three meals per day

    I mean... are you sure you want to use that study against intermittent fasting?

    This is great. You guys are posting some studies I haven't read before. Everybody learns. Everybody wins.

    You completely misunderstood the MATADOR study. That proved that taking diet breaks (eating at maintenance) improved weight loss. It said nothing about fasting.
    That's what I say in my post. read it again.
    While this study does not apply directly to daily IF, it shows that there is a significant difference between just continously reducing calories to a low amount or mixing it up a little bit with strict fasting and maintenance phases.

    What's that bit about strict fasting in there for? The MATADOR study doesn't mention it.

    The methology is explained in the paper. Losing more than 1 kg / week is pretty strict.

    Ignoring the animal studies (because you said you wanted human ones), and any and all “modified fasting” scenarios (because that’s not what we’re talking about here), it seems like the study you provided is fairly clear on its opinion of IF:
    It appears that almost any intermittent fasting regimen can result in some weight loss. Among the 13 intervention trials included in this review, 11 (84.6%) reported statistically significant weight loss ranging from 1.3% in a cross-over trial with a 2 week intervention23 to 8.0% in a 1-arm trial of 8 weeks duration.13”

    Notice the key word 'can' in the bolded above.

    And no one argues that IF can result in weight loss for some people. For those in which this does occur, it happens solely because they were in a caloric deficit during that time. IF works *exactly* the same way as any other method that restricts caloric intake. There's no magic, no additional benefits that can be shown.

    PS: I've been doing IF for decades. Long before it had a name and became trendy.

    If intermittent fasting works for fat loss solely because it restricts calories, can you please explain to me the results of this study that matched calories between the two groups? I must be missing something...

    While that is a really interesting study, the two things that struck me were that it was done on already trained athletes and the calorie intake was self-reported and not controlled.

    Still interesting though.


    I think so too!
    Here’s a different one where the eating was more controlled.
