Weight loss and healthy living trends change as quickly year to year as the latest textile pattern or hottest nail color. From carb-loading and strength training to eating saturated fats and exercising in only 10-minute bursts, it’s hard to keep up with the latest (and most credible) news in the healthy living industry. If you spent any time online or watching TV in the past year, you know 2013 wasn’t a quiet 12 months for breaking weight loss news.

FitSugar compiled a collection of the most interesting weight loss news of 2013 from researchers across the world. Do any of these surprise you? Any other news stories you think should make the list? We’d love to hear from you!

1. More Sleep Decreases Junk-Food Cravings: We’ve been learning more and more about just how important sleep is for our waistlines; this year, researchers showed that lack of sleep can actually change how we respond to junk food. When sleep-deprived participants were shown photos of fatty foods like pizza and doughnuts, the reward centers in their brains lit up much more than those who had gotten enough sleep — proving that when you’re sleep deprived, you’re more likely to make less-than-optimal diet choices than when you’re well rested.

2. Dark Chocolate Blocks Fat: Last year, it was red wine, and this year it’s even more good news: a new study found that dark-chocolate eaters who ate more calories than non dark chocolate eaters still had lower BMIs. The study suggests that an antioxidant found in dark chocolate, epicatechin, may block your body’s absorption of fats and sugars.
