Yeah, I had been working out at the Y in order to start mountain hiking in the North Cascades. I was building stamina and tone, but didn't start burning efficiently until I started hiking.
So I was carrying a heavy backpack, drinking lots of water while walking, climbing and sweating, changing altitudes and taking rest breaks. I was eating MetRX bars and ramen and every kind of protein I could store in my pack, like cheeses and jerky. It wasn't a balanced diet, but I'd switched everything up so drastically, my body adapted. When I wasn't in the mountains I ate healthy foods listed in my post-op diet (see file in Latest Resources section). I continued to work out at the YMCA because I loved it. After working out, I'd swim a few laps, then spa and sauna followed by cold shower. I was transformed because all my senses were involved in a physical activity.
Worked for me.
