The devil is in the details in these kind of studies. What raises red flags for me is how little weight was lost on the low carb diets. This suggests they didn’t really study low carb diets but rather “lowered” carb ones.
Also fruits are very high carb but they’re not all alike. What exactly were the carb loads of the various diets? The abstract isn’t all that revealing. Hopefully the full study becomes public soon.
My experience is cease bread and potatoes and sugary stuff....... that will do the job.
That is considered by me to be “reduced”
My DIL went on rigid no carb diet for several months and experienced very dramatic weight loss. For me, the reduced program produces results.
The American way is to always go to extremes. My experiece is the extreme is not really necessary
Whole fruits are best, not just the juice. And fruit with higher fiber (pears) helps save off the quick uptake of sugar that contributes to diabetes.
