According to research in the "American Journal of Clinical Nutrition," 37 percent of Americans' total daily calories come from sugar-sweetened drinks, including sodas and fruit juices, yet these calories do little to make you feel full. If you crave something sweet, a whole fruit provides more vitamins, minerals, and fiber, plus you're less likely to eat additional foods because the volume is greater in your digestive system.
A slow, low-intensity run uses more fat for fuel but takes longer to burn a lot of calories in total. That’s why it’s advised to run longer than 30 minutes when running at a low-intensity. However, a faster, high-intensity run can burn more calories in a shorter time period. And even if just a small percentage of those calories come from fat, it can still significantly boost your weight loss!
One study from the University of Adelaide in Australia suggests you may lose more weight when you work out towards the end of your menstrual cycle, as opposed to right when a new one begins. That’s because the hormones estrogen and progesterone tell your body to use fat as an energy source. "Women burned about 30 percent more fat for the two weeks following ovulation to about two days before menstruation," study author Leanne Redman says.
