The ketogenic contributors have been typically older and had a better BMI. Notable findings included increased cases of hypertension amongst ketogenic eating regimen contributors. Dietary patterns revealed that these on the ketogenic eating regimen consumed “ketogenic-friendly” meals extra ceaselessly and “non-ketogenic” meals much less ceaselessly than their counterparts.
