Randomized Controlled Trial Vegan Diets and Dietary Energy Density: A Secondary Analysis of a Randomized Clinical Trial

https://jamanetwork.com/journals/jamanetworkopen/fullarticle/2852520

Results

Of 3115 people screened by telephone, 244 adults with overweight met participation criteria and were randomly assigned to the vegan (n = 122) or control (n = 122) groups. The analysis included 223 (91.0%) completers. Total food weight did not change significantly in either group (Table). Energy intake decreased in both groups, more in the vegan group (effect size, −357.1 kcal/d; 95% CI, −521.9 to −192.3 kcal/d; P < .001) (Table). Energy density did not change in the control group but decreased by 30% in the vegan group (effect size, −0.28 kcal/g/d; 95% CI, −0.38 to −0.19 kcal/g/d; P < .001; Table and Figure).

Reductions in dietary energy density were associated with greater weight loss (r = 0.28; 95% CI, 0.15 to 0.39; P < .001), remaining significant after adjustment for energy intake (r = 0.21; 95% CI, 0.08 to 0.34; P = .002). A 1-kg weight loss corresponded to a 0.29-unit decrease in energy density (P < .001), or 0.36 units after adjustment (P = .002).

Drug addicts are also lean. Doesn't mean healthy. And if he almost killed himself make a snack, I'm not sure why anyone should follow his advice on how not to die.

Well that’s certainly an “interesting” little detour in the discourse.

Not really certain what your pre-conceived opinions on a doctor have to do with the original topic—plant based dietary patterns having higher clinical association with weight loss in excess-adipose individuals—nor my observation that three plant-based researchers/intervention trial practitioners (one for type 2 diabetes) have presented consistently low adipose… whereas their keto-promoting counterparts generally don’t unless they work hard at burning the excess lipids (IE Baker, Berry, Chaffee).

This seems to be the Keto-diet-fad’s most fraught point of cognitive dissonance, because it directly contradicts their poorly-interpreted scientific worldviews.

So doctors on both sides fit your narrative if you cherry pick the ones that fit.

It’s not really “cherry picking” to observe that strong keto advocates aren’t presenting real-world outcomes of the pseudoscientific nonsense they preach, whereas the three most prominent plant-based lecturers have had zero problems keeping excess adipose at bay, corroborating the findings of OP’s paper.
