I've done Keto several times, and while the results were always fantastic the hardest thing is that 3-4 day period where you need to watch what you eat to enter ketosis, one false move can reset your progress and really discourage you; however for me once I'm in ketosis I'm pretty disciplined at keeping it up.
If this drink can get me into ketosis quickly and allow me to maintain it by following the regular diet then I'm sold. I'll definitely be keeping an eye out.
