Glucosamine is a dietary supplement usually derived from shellfish families, shark or beef cartilage, and sometimes fermented grains.
It has negligible kcalorie value.
Its role in the body is essentially to construct cartilage. It shows no secondary side effects of initiating weight gain.
What most likely is the culprit, are the snacks.
If you still wish to keep up the glocosamine for his knees, there are liquids and pills that can be given to them with food. That way you can keep up the regime, but manage the kcalorie intake.
Good luck.
