I've found a lot of things affect my weight loss that aren't food related: not enough sleep, certain medications, fighting an illness/cold/flu. I also like to try a new recipe, but I time it after weighing in, just in case it doesn't have the desired effect. Sometimes mixing it up or eating certain foods earlier in the day can help, like restricted Brownies. Sometimes eating an extra IP packet earlier in the week when I'm really hungry. It try a different IP product. Hope this helps!
