Here is the full text of the study in question:
To test whether a distinct tRF regimen can prevent diet-induced obesity, we subjected 12 weeks-old male C57/BL6 mice to high fat diet (HF; 61% energy from fat) or normal chow (NC; 13% fat) under either ad lib or time restricted access to food during their natural nocturnal feeding time
I can't find that actual quote in the paper you linked, so maybe youre looking at a different paper(?)
BUT, it doesn't matter becaus it does say this,
"Diets used in this study are
a normal chow diet (LabDiet-5010),
a 60% high fat diet (TestDiet-58Y1),
a high fructose diet (Harlan-TD.89247),
and a high fat high sucrose diet (ResearchDiets-D12266B) (table S1)".
So they actually tested three diets (including the one you mention, and the one I was referring to). This actually makes the results even more impressive than Panda had stated in the podcasts...
If you look at Table S3 (the excel spreadsheet in the full text of the paper you link above), it shows improvements across all 3 diets for the Time Restricted Feeding (either by body comp, or biomarkers for health, or both).
Regarding calories consumed. I don't think anyone is saying TRF means not having to worry about the amount or the quality of the food you eat...
It is showing us that the TIMING of food intake may be as important as how much and what and could be why some people who watch how much and what they eat, aren't getting the results they think they should.
Yes people seem to respond to nutritional parameters on an individual basis, maybe also for the parameter of timing. To disregard it as a parameter worth looking into, after looking at those results seems to indicate a rigid view...
Maybe I welcome this sort of thing because (I like to think) I look at the human as a complex system (...within a complex system etc). The better complex systems can follow their natural dynamical synchronisation, the more adaptable they are, and the more organisation (evolution/growth) can occur.
What if a departure from some long forgotten diurnal patterning has led to a chronic foundational stress. Those markers they're looking at, inflammation etc... Right there that's immune function, dysregulation of an ancient, intelligent system (...did someone say cancer etc). Plus cytokines can induce expression across the blood brain barrier so that then leads to impaired contextual information and what we are learning about cognition, neuro development and degeneration etc...
I don't want to seem too excited, but I am certainly interested in where this can go as far as helping with improving people's lives.
As to that ugly woman with her strawman anti-paleo rant on TEDx... Just as bad as that other cynical self-promoting cunt with the TEDx talk about stress being good for you... Jesus... I've never been a fan of the whole 'paleo' thing, but this trend of doing 'clickbait' TEDx talks to enhance professional exposure will be looked back on as the scientific profession's version of doing a sex tape.
