We get this question a lot because there has been so little guidance in the past on how to eat for maintenance.
I designed an entire structured Phase 3 program now though called P3toLife, that women are doing AMAZING on- they are stabilizing perfectly well, very reliably, and in some cases even losing weight, all while feel satisfied with how much food they are eating- if you are really nervous, you might want to check that out as if tells you exactly what to cook and eat and the food is delicious and will really help stabilize and lock in your new weight.
You can check out interview success stories of P3toLifers, as well as written testimonials.
This will help you get a feel for the success rate of the program.
I hope that helps!
