3. Drinking packaged fruit juice
Most people who want to lose weight stop drinking soft drinks and other drinks with added sugar. But they often forget about fruit juices that come in a bottle. Even 100 percent fruit juice has enough sugar to mess up your plans to lose weight. For instance, 12 ounces of fruit juice that hasn’t been sweetened may have about 36 grams of sugar. That’s more than what’s in a 12-ounce soda.
