What's the best way to start a healthy diet?

Follow the following: Exercise most days of the week (aerobic work), eat fruits and vegetables liberally, limit saturated fats, increase fish and fish oil intake, have fiber with each meal, get six to nine hours of sleep nightly, keep your weight in check, don't sweat the small stuff, don't smoke or drink excessively (one or two drinks weekly), don't do drugs, do your health screening.

Just do it!: If you are the predominant food preparer, find some fun cookbooks that incorporate fiber sources with meat products; buy leaner cuts of meat, and start introducing fruits, vegetables, and whole grains in forms you will consider eating. You can't force anyone to eat healthy, but you can certainly stop buying junk foods, cutting portion sizes, and encourage better meal and snack choices.
