Lack of sleep negatively affects my weight loss. I also seem to need variety. I change up my IP foods, plus veggies & proteins throughout the week. Salmon & steak are fairly reliable weight loss inducers. Turkey burgers were best in the beginning. I also broke up my protein between lunch & dinner but I don't do that as much now. I suggest trying new recipes, different IP foods, WF dressings to see what works best.
