I've had little slip ups. Like, if I didn't have a snack on me, I would find a low carb snack. For me personally, I need to do this. I'm a perfectionist and freak out when I don't do something exactly, then I spiral then quit relapse into disordered eating. This is me being kind to myself, which I am not. When I'm kind to myself, I easily get back on track. I know this is a unpopular opinion, but this is just me. I know at the end of the day weight loss is about calories in, calories out. IP just makes it easier. I try not to slip up too much because I will get super depressed (its a hormonal thing). If you're gonna slip up, don't slip up too much. Go to the meetings and see how what you ate affected your goals.
