I may be reading your post wrong but have you just started January 1? You need to give it some time. Keto is not a magical way of eating that causes pounds to be lost daily. As @GentleBen said that equals 8 lbs a month and you really don’t want to loose weight faster than that. I think you’re fine.
As @DiMo said “one week does not a stall make”… A stall is like 5-6 weeks without change.
These people both gave excellent takes on your situation.
And my personal advice is that you need to think of this as a lifestyle change, not a quick loss diet. Lifestyle changes are sustainable, dieting and going back to the foods that made you overweight in the first place is a roller coaster that will deteriorate your metabolism and health.
There’s a ton of stuff going on now in your body other than shedding some weight. Your metabolism is changing and body repairs are underway.
