Sometimes its hard to find a fit. My mom is 85 and very active. Keeps house , gardens, travels, etc between bouts of health issues ( broken foot, cancer, etc) She cooks wonderful meals , just for herself. And surprizingly she has sliwly dropped pounds, back to her original weight which in her mind is when she got married. She looks great. But her body is not the same outline as then. Thats ok. She is busy busy busy.

If you can, increase activity until "sedintary" is a thing of the past. Mucsle uses a lot of energy even when sleeping.
