Eat well: People will tell you different things, but as long as you maximize your green vegetable and fruit intake, while minimizing processed foods, you’re eating pretty well. Buy organic produce as often as you can: the difference in things other than price – like taste and nutrition – is very noticeable. Eating smaller meals and sticking to “natural” foods like nuts, fruits, veggies, and meats is a nice rule of thumb, though you can eat some carbs as well to give you energy that lasts throughout the day.
