Your husband's Body Mass Index is generally characterized as "Overweight".
Losing 5 - 10 kg would be a reasonable goal for him (he would then be in the
"Marginally Overweight" category).  Losing 12 kg would put him in the
"Normal Weight" category.  A healthy target for Body Fat percentage would be
15%, depending on his age.

This web site has a lot of good information on the meaning of Body Mass
Index and how to interpret it:

25% is pretty high for a man. It's even the top of the healthy range for
a woman, and men should be 8-10% lower. That said, bodyfat scales can be
pretty inaccurate. Is there any reason he would be overweight without
being overfat - i.e. does he do any activities that would build serious
amounts of muscle, and does he have a very large frame? And does he have
any noticeable tummy flab? That's usually where men gain first and lose
last.
