Hopefully I can be of use! Let me give it a shot:
First, is it possible we can talk about health and about having a good relationship with food, and about enjoying the food you eat? I think I've had it up to here with the fat-focused, fat-phobic effort that women do to conform their body to the image that's been put in their mind about when they can finally feel good about themselves, etc. I mean, I *want* other women to like their bodies, to like their food, and to have excellent health, but I swear, I just can't take another conversation about the scale as the God of Our Existence. My personal pet peeve.
So, then if we actually do talk about adjusting your eating so that you're able to make your body healthier and, OK, smaller -- then we're just going to have a boring conversation about calorie density, and about meal size and meal frequency. It's not rocket science -- just about eating three meals a day, if that's the number you like, and making sure to give your body adequate time between meals. (I mean, the body, however much love and affection we give it, needs time to digest and to use up old fat stores. Don't deprive it of that.)
Also, it would be worth tweaking the calorie density of what you eat. Eat a bigger bowl of steamed vegetables with each meal. Portion your starches and legumes *slightly* downwards if you must. Keep your consumption of simple sugars low (1-2 pieces of fruit is probably fine, but you don't technically need any simple sugars in the course of the day).
But most of all, find ways of eating that don't feel like punishment, and then you're not sitting there wanting to protest your own way of eating and go back to (?) Weight Watchers. I mean, that doesn't sound like fun at all, but who am I to know if that's an empty threat or not!
I don't know. See what you can do with it. You'll figure out a way if you want to, whether within a starch-based WFPB lifestyle or not.
PS -- Good job on all the exercise and all the effort you've made so far! I think you can harness all those right things if you're willing to put more effort in. (It's worth the effort! Why not just put in the time to get it right???)
