The basics are the same. The biggest change with Momentum is that they encourage you to eat from a list of 'filling foods,' primarily fruits, vegetables, and whole grains. So it's flex with a bit of a twist.
They have also added a 9th HG of "Exercise at least 30 minutes most days of the week." WPA are used before AP because they are encouraging people to use WPA and not eat AP to enhance weight loss.
So, if a person was following Core and only having to note points for a few things, is it still the same or do we have to note the points for everything we eat, as in the Flex plan? I'm very confused.
