Some things that enhance ketogenic or non-ketogenic diet (or higher carb) when you hit the plateau stall point mark and that is Glutathione production (Milk Thistle/Silymarin/Bone Broth), foods high in Selenium (not a good idea to supplement too much) and most important Choline (eating liver and/or eggs) and some DHA/EPA from marine life in the diet along with a little bitter melon extract made me lose weight rapidly when the scale quit moving.
I like to look at waste circumference, height and muscle to adipose ratios in contrast to body weight to get an idea how long it will take to burn actual body fat!
If I notice loose skin I cut back on the protein intake or fast!
