When I started this vegan++ ETL diet, I also started exercising as much as possible. I've tried to swim every day except when I was traveling. When I started, I was barely able to finish 100 meters without feeling really tired. I have been pushing my total swim time and distance every day. Today I swam 2.5 km in just over 1 hour. That's not very impressive for people who swim a lot, but I've been swimming like this for only a few weeks and I feel pretty good about it. (I used to swim in Jr. High School 30 years ago.)
Various people have been telling me that losing all of this weight and eating only veggies and fruit would not give me enough energy, but every single day, my stamina is increasing. I really don't think it's just some sort of calorie deprived hallucination. I've never been able to swim 2.5 km before. (Again, I realize this isn't a controlled experiment since I never tried to swim this hard since Jr. High School....)
Today was the end of the 3rd week of the 6 week program and marks the half-way point. I will write more when I'm done, but I wanted to post this since I was getting email from people worried about my health. Of course I still don't know everything that is going on, but everything that I can feel and measure seems pretty great at the moment.
