By learning about my body and making small, subtle changes, I find out what I enjoy and what is effective. I'm always finessing: adjusting my diet and my workouts. You have to figure out which exercises are fun and interesting and stimulate your brain - or else you'll never keep at them.

If you eat a lot of starchy foods, introduce a vegetable once a week, then twice a week, and then three times a week. Slowly fill your diet with new flavors. By the time you're ready to let go of whatever it is you want to let go of, you've got a full menu.

I'm on this diet where you're supposed to eat only fish and meat.

My doctor explained that exercise and diet changes might help and that I also might need a medication.

Meat is a wasteful use of water and creates a lot of greenhouse gases. It puts enormous pressure on the world's resources. A vegetarian diet is better.
