Iv been doing fast 800 for almost 3 weeks now. First 2 weeks were great, lost 17lb but now nothing has changed for last 5 days, I even gained a lb on one day! I’m using an app to track macros, I’m eating less than 20g carbs, 100g fat and 100 protein each day and calorie intake is between 400-800 calories a day. I’ve tested and am definately in ketosis.
Exercise is limited for me due to health conditions and I know my meds cause weight gain so that contributes but I cant go less calories a day!
