What's Really Ruining Your Diet Don't Let Bad Habits Keep You From Losing Weight So you're eating well, working out, and that number on the scale still won't budge. Even worse: Between tailgating season, Halloween, and the holidays, losing weight is about to get even harder. There is good news, though. You can take control. Just eliminate these surprisingly destructive habits and the sneaky foods that are responsible for destroying your diet. Habits That Ruin Your Diet You're Drinking Too Much Most people overlook liquid calories entirely, says Felicia Stoler, registered dietician and author of Living Skinny in Fat Genes. So don't expect to notice when a seemingly single-sized juice can or bottle actually contains two or three servingsâand two to three times more calories. Your best bet: Replace juice with water, and eat your calories instead of drinking them, she says. For some H2O inspiration, check out 10 ways to drink more water. You Eat Fruity Yogurt Most fruit-flavored yogurtsâand plenty of other healthy-sounding foodsâare sweetened with fructose. But unlike other sweeteners, this one doesn't tell your brain you're full, according to a new study. The result: You end up eating way more calories than your body actually needs. Your Fave Team is Losing Turns out, you're more likely to binge eat the day after your sports team bombs a big game, according to a 2013 French study. You Hit Up Happy HourâA LOT People don't realize just how many calories they drink, says Stoler. What's more, the alcohol in your cocktail can reduce your inhibitions, so you hit the happy hour menu (hello, nachos!) even harder. To imbibe without overdoing it, stick to one of these delicious cocktails under 200 calories. And switch to water after drinking one or two of them. You're Overdoing It at Breakfast While the standard serving size for cereal is about two-thirds of a cup, breakfast bowls can hold much, much more. So when you fill yours to the brim with cereal, and top it off with milk, you could be eating twice as many calories as you thinkâor more. You Treat Yourself a Little TOO Often When you indulge in sweet or fatty foods like ice cream regularly, you end up craving larger portions to feel satisfied, says Stoler. Need a sweet treat every day? A new study published in the journal Food Quality and Preference found that a few bites really will satisfy you just as much as a larger serving. You're Guzzling Diet Soda Drinking calorie-free sweeteners is like dumping water in your gas tank instead of gasoline, says Stoler. For non-mechanics: It fills you up, but doesn't keep your motor running. When hunger strikes, drink water instead, and fill up on wholesome foods to drive off hunger pangs later. The Worst Drinks In Your Supermarket You're Depriving Yourself When you cut out whole food groups (like carbs or fat, for instance) you set yourself up to binge eat them the next time you let yourself splurge. So instead of crossing them off your grocery list, entirely, learn how to manage your strongest cravings with these tips. You Order the "Regular" Size Think you're in the clear because you downsized your large order of fries? Turns out, people actually consume more calories when they order regular-sized menu items than when they order portions advertised as "double-sized," according to a new study. You're Staying Up Too Late People who hit the sack on the late side tend to eat more high-fat and high-calories foods than those who tuck in earlier, according to a recent study. No wonder they also gain more weight. 20 Habits That Are Making You Fat
