Gut health and weight management are closely linked—and it’s no secret that your diet plays a significant role in both. But while we often consider the foods we put on our plate, it’s easier to forget the impact that the beverages we drink could be having on our digestion and our waistline. As it turns out, many popular, sugary drinks could be sneakily sabotaging your health goals.

We spoke to Dr. Paul Gross, Medical Doctor from LIV3 Health to get insight on a few of the most common culprits. From soda to fruit punch, find all of his warnings below.

1. Regular Soda

Many Americans reach for a can of soda on a daily basis. Unfortunately, this is bad news for your gut and your waistline. Like many sweet drinks, sodas pack in a load of added sugar without bringing any nutritional value to the table. Because of this, Dr. Gross explains, "Frequent consumption has been associated with weight gain, insulin resistance, and metabolic dysfunction."

Instead of grabbing that Coca Cola, he recommends opting for sparkling water with citrus or other naturally flavored, unsweetened beverages.

2. Sweet Tea

Tea may sound like a healthier option when compared to fruit juice and soda, but when you add sugar to the mix, it's really not much better. In fact, Dr. Gross warns that "many bottled and restaurant sweet teas contain sugar levels comparable to soda while creating the perception of being a healthier choice." All in all, sweet tea can be just as bad for your digestive health and your weight management efforts.

The good news is that you can still enjoy a refreshing beverage. Just skip the sugar; Dr. Gross recommends unsweetened iced tea with lemon, or herbal iced teas.

3. Energy Drinks

If coffee doesn't cut it when you need your afternoon pick-me-up, you might choose caffeine-loaded, sweet energy drinks instead. But in addition to the negative effects of all that caffeine, the sugar content of these drinks can do a number on your gut. "Many energy drinks combine high amounts of sugar with caffeine, creating rapid blood sugar fluctuations and unnecessary caloric intake," Dr. Gross explains.

This doesn't mean you should cut out caffeine entirely, but he suggests swapping your large Red Bull for black coffee, green tea, or low-sugar electrolyte beverages.

4. Sweetened Coffee Drinks

Speaking of coffee, it's important to remember its best taken black (and can even boost your metabolism this way!). While sugary options like Frappuccinos are certainly tempting, they can be a nightmare for your health, especially if you struggle with your weight and gastrointestinal issues. "Specialty coffees can easily contain hundreds of calories and significant amounts of added sugar from syrups, flavorings, and whipped toppings," Dr. Gross says.

If you really can't take the taste of black coffee, go with a small amount of milk or a lightly sweetened, protein-based coffee drinks, he says.

5. Fruit Punches and Juice Cocktails

Fruit juice often sounds healthy. After all, it's made of fruit! However, beverages like fruit punches and juice cocktails rarely contain the nutritional value of whole fruit. Dr. Gross explains that "they often contain added sugars and very little fiber."

Your best option is to eat actual fruit. For a fruity, healthier beverages, you can even infuse water with your favorite citrus or berries—or, Dr. Gross suggests, add a small splash of 100% fruit juice to sparkling water.

The Bottom Line

When it comes to your diet, it's important to remember to consider the beverages you're sipping on. Dr. Gross points out that "liquid calories are uniquely easy to overconsume because they do not create the same fullness signals as whole foods. For many patients, reducing sugary beverages is one of the simplest and most effective ways to improve both metabolic and gut health."

He concludes with a good rule of thumb: "If a drink delivers a significant amount of sugar but little protein, fiber, or nutritional value, it's probably working against your long-term health goals." We'll remember that!
