If you are 56 years old and only have a few pounds to lose you may not find losses as quick as those with 50+ pounds to lose. I started keto at 130 lbs with about 20 lbs to lose and although the first few pounds melted off quite quickly, the last 10 were a struggle of figuring out what was making me hold those last pounds.
Now, at a month in only, I wouldn’t really worry. You’re still probably fat adapting and should eat when you are hungry. But ONLY if you are hungry.
If in two more weeks you still aren’t seeing any changes (and look at measurements and clothing fits, not just scale weight), then there are several things that will likely help.
First, as @Brennan suggested, count total carbs. I don’t do this for everything but I do it for ALL proccessed foods (so from your meals I’d count total carbs for the bread and the Atkins bar.
Second, once you’re fat adapted you will not need to eat as frequently. So initially you should drop all snacks. If you find you get too hungry between meals then eat more at mealtimes. Eventually, you will be able to go longer and longer without real hunger. This leads to longer and longer periods of low insulin which is when your body will turn to its fat stores.
Finally, I recommend getting rid of most of the deserty elements. If you’re sweetening your food then you are likely messing with your body’s signalling and you will continue to crave foods when you otherwise wouldn’t.
There are many other tweaks that some people on this WOE find they must use to achieve their final goals, but you aren’t even out of the adaptation stage so I won’t overwhelm you with a list you may not need at all.
As to your specific questions. The macros should be seen this way.
Twenty net carbs is a hard maximum. Fewer is better, and just don’t trust those “fibre” carbs on proccessed foods. Many here even use total carbs.
The protein macro is an aim. Try to hit it relatively closely but don’t obsess about a few grams up or down. Myself, I shoot more for a weekly average.
The fat macro is NOT an aim. It too is a maximum. You are only supposed to add as much fat as you need to not be hungry. Eating to and past your fat macro is likely why you are stalled. If you are eating your full fat macro when not hungry for it you are just giving your body food fat to metabolize INSTEAD of the fat on your body. This diet trains the body to metabolize fat and deprives it of carbohydrates so that it has to metabolize fat. But if you give it enough fat off your plate for all its energy needs then it never has to run to body fat at all.
I hope this helps.
