You’ve been killing your workout game for a few weeks now (do it, girl!) and you’re feeling pretty darn good. Your pants fit a little better, you have the energy of a 12-year-old, and you can do twice as many squats as you could three weeks ago.
Then you step on the scale and you’re… five pounds heavier!? Umm, what??
Before you totally freak out (remember how good you feel?), check out these reasons from Women's Health why why might be experiencing some unexplained weight gain.
Your Bod’s Retaining Extra H2O. Within a week of hopping on the sweaty bandwagon, you may notice weight gain. “When you start exercising, your muscles start gobbling up fuel called glycogen,” says Krista Scott-Dixon, Ph.D., Director, Headspace Adjustment Bureau, Precision Nutrition. Since glycogen stores water, you could gain up to 10 pounds in water weight alone, says Scott-Dixon. As long as you're exercising regularly, yes, you're going to carry around some extra agua.
Before you side-eye that bottle of water you’re drinking, remember that this is just your body’s way of preparing itself to kick ass when you work out. Again: It’s not fat, just water.
You Might Be Nomming More. While some people say exercise suppresses their appetite, others leave the gym ready to eat the world. “I’ve noticed that many women tend to eat more when they’re working out,” says Scott-Dixon. That might have something to do with our bod’s natural desire to store fat for baby-making purposes. Your brain sees body fat as energy available for reproduction. So if your weight is in the proper baby-making range for your bod (which varies from gal to gal) — but then you start burning way more calories — your appetite might ramp up in order to maintain that amount of fat.
