This isn't even a study! The author just draws unfounded conclusions from nothing as usual with these type of articles
"Different diets (e.g., high-protein/low-carbohydrate vs. low-protein/high-carbohydrate) lead to different biochemical pathways (due to the hormonal and enzymatic changes)"
The usual: he compares high carb, low protein diets to high protein, high fat diets- which tend to have better adherence anyway, and have umm... HIGH PROTEIN.
Which is the single most important determinant of weight loss and quality of weight lost behind total kcal intake. No one is contesting that. And he still manages to fail to support his contentions or reference anything.
Then the rest of what he talks is about diabetes patients, his primary evidence, which obviously aren't a reliable model for the average trainee. Pleaase.
Every study I ever see supporting the anti-carb agenda is like this, and it is getting old.
Let's see a reputable source, doing a controlled long term study, in laboratory conditions, with isocaloric, isonitrogeous diets exchanging fat and carbohydrate intake that shows any advantage in weight loss or quality of weight loss for fat.
Not only does this not exist, but some research has shown the opposite to a degree- that carbs provide a more readily available energy source and by this pathway can increase metabolic rate by up to 4% compared to the fat treatment.
Want a good perspective on this "issue":
the discussion in the comments section is quite enlightening
I don't think the research says what you think either. And from what I've read, I have a feeling that JM has done more reading than the average guy who has read a book by Taubes and a handful of (potentially biased) articles across various bodybuilding or low carb websites. There is a pretty big contingent of individuals out there who seem to enjoy make believe physiology. I don't blame most, and have no problem with people disagreeing with me.
But I post regularly on another small forum not re: to BB or nutrition, and the occasional influx of relentless anti carb, everyone should eat 100% meat diet zealots who post their opinions like a fact and back them up with inconclusive studies and make believe physiology get on my nerves!
Maybe this gives an idea of why some of the people on the other site of this issue (check out bodyrecomposition) are kind of an angry bunch when this gets brought up.
Regardless of all this, my opinion is that people need to get with the picture. Create a deficit. Eat lots of protein. Eat nutritious foods without baseless discrimination. Train smart. Worry about the rest when you are at your genetic potential and dieting to contest condition because otherwise it's rarely ever going to make a real difference.
Advice I wish I took myself more often to the point I feel somewhat hypocritical giving it, but there you have it.
I have nothing against ketogenic diets or people doing the AD either and wish the original poster best of luck! I've done similar plans myself and enjoyed sweet results for the most part. I am merely commenting on some of the assertions re: the literature and high fat diets.
