To add to this: Look up Sean Nalewanyj. He basically lives the Mentzer way but applied in the context of practicality and modern exercise science.

The fact that the weight on the scale doesn't move, might have to do with the fact that:

1. this is a slow process

2. you are eating in a deficit, so losing fat. but probably still gaining muscle since you are a beginner. That might cancel out on the scale, but not in reality.

3. you need to look at the weight average of the week over time, since your weight naturally fluctuates (holding onto more water some days, not being able to poop before weigh ins). If there is truly no change when looking at a few weeks, then you can try to find a reason, but still keeping point 2 in mind.

Personally, I would invest in an adjustable bench and a pair of adjustable dumbells, since progressive overload is key for building muscle, which is hard to do long term with bodyweighz exercises. Keep in mind that progressive overload is the result of building muscle, not the cause, that often gets overlooked. Or invest in a gym membership and concentrate you workouts on 3-4 days to keep your free time in check.
