I'm going to give the pound a day a try(only need to drop 15) but have a question:
1. Will working out in the evenings compromise this program?
I work during the day and exercise in the evenings out of convenience. Working out in the mornings would have me waking up unreasonably early. I'm pretty good about getting daily exercise, and am a little chub from eating to much too late.
I don't think it would matter. You should only avoid heavy exercise late in the evening as it will hinder you from sleeping.
I have read that people have differing optimum times in the day for exercise. This can be worked out from experience—probably from what you generally feel works best for you.
There is also preference (which probably relates to the above). I, personally, prefer to do cardiovascular/aerobic exercise in the morning (it wakes me up) and strength/anaerobic exercise in the late afternoon/early evening when my muscles are looser and more warmed up (I also don't like to ache too much during the day at work).
Finally, there is also convenience. Ultimately, it's better to do exercise at any time rather than none at all (except perhaps for late at night for reasons already stated) and if you feel that you are more likely to do your exercise if you do it at a particular time of the day then you should just stick to doing it at that time.
Other than these, I don't think there is a particular physical advantage to working out in the morning over later in the day.
(I am not medically qualified but the above is gleaned from several sources who are. Of course and as always, use at your own discretion and seek proper medical advice before any exercise.)
What about this whole "every hour" thing. I work! I work a LOT, thus, the *ahem* lack of body I want. I have a fridge so I'm not too worried about the food thing, but no way in hell am I getting up in my suit and doing 2 minutes of jump rope.
How about running up and down some stairs if you have them? I've heard this is one of the best forms of exercise and convenient too. You also won't look silly in your suit!
The other thing I can suggest, if you can get outside, is a brisk walk around the block.
