thanks... helps give a better picture. being 6'/4", i'm guessing your goal would be around 200lbs which is right on the cusp on a healthy BMI. all i can offer is that as you lose weight, every pound becomes less a percentage of your body weight, so things will tend to slow down, but where i started (about a BMI of 32) is where you are now. that was my plateau for a long time, but that was also before i discovered a lot about nutrition. if you are on a Keto diet, you should already be aware of those concepts.
one thing i did notice... when i first started losing weight, it wasn't always a strict linear decline. it helped that i kept daily track (sometimes multiple daily) weight checks. in the short term, it didn't really show much, but when i graphed it over weeks and months, i could see a definite downward trend. i used to celebrate each new low and highs that seemed to eventually disappear from the chart.
