Trying to lose fat by eating less and less and running more and more doesn't work. That is, you'll conserve calories and thwart your efforts to lose fat. The better bet is to exercise reasonably and to increase your food intake early in the day to fuel your training. Eat breakfast, lunch and an afternoon snack. Then eat lightly for dinner and afterward.
Morning is the best time for women to run, for lots of reasons.
Two, studies have shown that morning exercisers are more likely to stick with it, because what you do first thing in the day gets done. Three, it saves you a round of dressing, undressing and showering at lunchtime or later. Four, it gives you a feeling of accomplishment, which is a great mental and physical start for the day. One of the smartest things a woman runner can do is to include strength training in her weekly regimen. Running doesn't make your breasts sag or make your uterus collapse.
