I can tell you my success is tied to drinking enough Water. I hit a plateau last month and then noticed I wasn't drinking the amount of water I was previously.
I wasn't eating Breakfast because I wasn't hungry. I started eating a Protein Bar for breakfast and drinking more water and I'm losing again.
Be patient and just follow the rules. I have lost 70 pounds since early September. I'm half way to my goal! Good luck. Be strong. I know this works. My sister lost 120 in a year and a half this way. Just takes time and your determination to follow the rules.
