So I bought a Xiaomi Mi Scale.

Whilst I know not super accurate, it has made me curious on 2 of my readings:

1) Protein is low (not muscle, just protein)
2) Low basal metabolism (about 1300 when it should be about 1500)

Some notes:
1) I exercise every day early morning, mix of weights, HIIT and running.

2) I have a few kilos to lose also.

3) Rest of the measurement are fine.

4) I practice 16/8 intermittent fasting (eating window 12-20) since a few years and I like it.

I started researching this but am a bit at a loss on how to increase both figures?

I tried protein shakes but there is so much advice out there I got a bit lost.

Anyone has any word of wisdom on this topic?
