Massimo, it's hard to say.
There are several things to consider:
First of all, you don't have that much to lose, and the last few kilos are the slowest, usually. So you may just be having a natural slow-down.
Also, are you measuring, or just weighing? Lot's of people lose either weight, or inches, but not both at the same time. In my view, inches are better
And, are you exercising? If so, the muscle you are building can be taking up the weight you are losing in fat. Once again with as little as you need to lose, it would be hard to tell.
If you post what your typical daily menu is, it might be easer to tell. Salty food can make you retain water, in which case the sausage/bacon might be the culprits.
Other things that influence it:
If your fat intake is not high enough, or if your calories are too low, that can also affect losing. And, dairy stalls some people.
So - there's a lot to think about...
In any case, I hope this helps.
Good luck!
