I can lose weight on those ratios but then again I’m a male and we do lose weight at twice the rate. Have you gone days without eating carbs at all? I do that regularly.
My wife is a bit shorter than you and is going from 152lbs down to 141lbs maybe from there she’ll do more but that’s her target. She’s all over the place with her weight up some days and down the next but over 7 weeks there is a steady trend downwards towards that goal. We’re eating roughly the same amount but she’s sneaking the odd carb without me knowing (she eventually tells me) and she’s dropped 10lbs in the same time that I’ve dropped 24lbs.
Yesterday she really hit the wall because she finally stuck to the diet and didn’t eat any carbs by 4:00pm she lost all her energy, felt nauseous and had to sit down. I said that’s the Keto flu right there, we weren’t far off preparing the evening meal with pork belly on the menu, so she hung on with a few carbs, and came right after eating the evening meal. So my point is you can lose weight even if you don’t follow the Ketogenic diet to the strict letter but ideally that’s where your trying to get to.
I wouldn’t say you are doing anything wrong based on those numbers others can confirm, but if that was me I’d be getting rid of those carbs altogether and see what happens. We’re all individual so what works for one person might not work for another or produce the same results, there is a point where you need to tweak things to find out what works for you and stick to it until it doesn’t work anymore.
