Hello! I know it's really difficult, but try not to worry so much about the fact that the scales aren't moving. You are guaranteed to be in a calorie deficit, so it's scientifically impossible for you not to be losing fat. I know someone who had the surgery and didn't lose any weight in the first 8 weeks, but she's lost absolutely loads of inches from all over her body, her body shape and size has completely changed! You should take measurements, then you can see the progress you're making even if the scales are being stubborn. Energy wise, are you taking all your vitamins? If you're not taking B12 you'll have really low energy. I find (6 weeks out today) that if I don't take my vitamins I feel absolutely blah, really tired and lethargic. Hope this helps!
