Myth 6 actually does have quite a bit of interesting research to support it -- namely that working out before breakfast was more effective for
preventing weight gain in a group of college-aged men who were force-fed a hypercaloric high-fat diet. They gained less than the group who worked out after eating and group that did not exercise.
On PubMed:

Most of us aren't college-aged men fighting off force-feeding of fat (ha) so this isn't necessarily relevant for women. But morning exercise isn't without its merits as an idea. Morning workouts are also good for curbing appetite through the day, and raising energy levels. And they are easier to turn into rituals. But of course working out any time is better than not at all.
