I was in a very similar situation and my dietician sent me this checklist:
o How often are you weighing yourself? Try not to weight yourself more than 1-2x week. Stress from seeing the number and being frustrated can actually stall our weight loss as well.
o Are you consuming liquid calories? Juice, smoothies (not protein shakes), alcohol, etc. can add empty calories and provide little satiation. Instead, opt for water!
o How are your food choices? Poor food choice may result in increased calorie intake. Try minimizing high-fat protein sources such as cheese and peanut butter.
o Are you consuming enough protein? Aim for 70+ grams per day.
o Are you drinking enough water? Aim for 64 oz. per day.
o Are you getting enough sleep? Aim for 6-8 hours of sleep per night to reduce stress hormones causing sugar cravings and increased fat storage.
o Are you walking? Until cleared by the medical team daily walking and staying with light activity is recommended and encouraged.
I had been following most of these, but I was weighing myself everyday, only getting in about 60g of protein, and maybe 48oz of water. I changed all of those things and in one week I dropped 5lbs. If there is anything on this list you aren't doing or having trouble with, then I'd start there. Good luck!
