Oh yes. Most definitely don’t compare yourself to others. There are too many factors which influence our rate of loss: age, gender, staring weight, genetics, etc.. If you’re losing a couple of pounds a week on average you’re doing fine. As long as your weight loss trend is going down you’re golden & celebrate every pound & inch you lose. Don’t forget you likely will experience stalls along the way when you do t lose anything for a week or more.
Watch keto. It’s very high fat & you may find your cholesterol levels are higher as your losing weight as it’s released from your fat. Better to look to low fat, low carb, low sugar high protein while you are losing. What plan did your surgeon & dietician give you? I’d avoid the popcorn too until you’re in maintenance. It’s very easy to overeat slider food.
Congrats on your weight loss so far.
