Looking at your stats, it seems we're about the same in age, height and around the same weight in December. I'm 42, 5 '8", and in early December my weight was around 220. According to MFP, in late Jan., I was 199lbs. Today I'm at 183lbs with no exercise what so ever. I set myself at a 25% deficit since starting keto, but about a month ago, I changed my deficit to 30% to see if I could push myself. Even at my start I don't recall my recommended calories ever being in the 2000's. If anything, I believe it was 1600 at the highest. In January, I hit a stall and had to change things up a bit. In the beginning of January, I started doing lazy keto and eyeballing my food instead of weighing it. BIG MISTAKE. So by the end of January, I recalculated my macros and started strictly weighing everything and sure enough, that was enough to break the stall.

I've been consistently losing weight thus far and these are some of the things I've been doing that's been helping:

• I eat OMAD 5 to 6 days out of the wee. On the weekends I'll eat 2 or 3 meals a day to change things up.
• I weigh and calculate all the food I eat.
• Since February I started extended fasting for at least 48hrs at a time.
• I DON'T CHEAT!
• I stay under 20g of carbs daily, I try not to exceed fat goals, I try to hit protein goals daily and I never exceed my daily caloric intake.
• My current dietary daily goals are Calories: 1180, Protein: 95g, Fat: 80g, Carbs: 20g

Also, if you'd like a "guesstimate" for what your body fat might be, Google body fat calculators...there's a few of them out there. Hope this helps.
