If I'm going to run/bike/swim I would eat Spirulina, Goji Berries, and Bee Pollen. When I want to calm down I eat Cacao (although Cacao won't work for everybody to calm down.)

 

Sounds like it would be best for you to see a medical professional and get a complete assessment of the entirety of your health.

Could be a Holistic MD or integrative medicine MD, doesn't have to be any old doctor.

And they can assess what might be going on and might be the problem.

Switching to a vegetarian diet can not cause what you are describing. It could be caused by food allergies or some other issue, but a vegetarian diet is not going to drain your energy levels.

Or, the vegetarian diet you have engaged is not complete and not filled with all the nutrients that you need.

So, best to have a medical professional assess what is going on.

Also, I might mention that, at 70 years old, doing hard core exercise is not necessarily medically wise. You should also have a medical professional assess your exercise program, just generally, aside from any dietary changes.

Sure, some folks can engage high levels of exercise at 70, but the percentage of people who medically should not do so, is not insignificant.

Best of luck..

 

Also, generally, re exercise and vegetarian diet...there are endless articles in major magazines discussing this. There are articles in runner's magazines, bodybuilder magazines and on.

and here's a general article from The Mayo Clinic on getting a healthy vegetarian diet. It should be noted that the Mayo Clinic is an internationally (highly) respected medical clinic...from mainstream medicine, not just alternative medicine...
