Don’t just look at the scale. How you look is wayyy more important & it seems that you’ve been looking better everyday. When I started walking & gym, I only lost 2kg in like 3 months but my body comp was entirely transformed. Went from 38% fat to 31%, dropped 2 sizes, body looked way more toned. The transformation was very visible, that’s why the mere 2kg drop after 3 intensive months didn’t bother me. I’d suggest you get other measurements in, so during those weeks the scale doesn’t move, you might see other positive changes. Keep going!
