The ketogenic diet is known for being restrictive. The low-carb, high-fat diet only allows you to get about 10% of your daily calories come from carbs — and to maintain ketosis(the process by which your body uses fat as an energy source rather than carbs), dietitians say it’s best to keep your carb intake between 20-30 grams per day.
Naturally, this means you’ll have to ration out your carbs for when you really, really want them. This means that you probably won’t be drinking your favorite sugary beverages on the Keto Diet. Even so-called “healthy” drinks are chock-full of carbs: an eight-ounce (236ml) glass of orange juice, for instance, has 27 grams of carbohydrates.
So what can you sip freely and what should you avoid? Here’s a handy keto-friendly beverage guide.
Can you drink juice on the keto diet?
Only if it’s diet or reduced sugar juice. Most fruit juices are high in carbs, which makes them almost impossible to drink on the Keto Diet, according to Dr. Mike Israetel, a sports nutrition consultant and professor of exercise science at Temple University in Philadelphia, PA. Case in point: eight ounces of cranberry juice has 30 grams of carbs. Apple juice? That’s roughly 24 grams of carbs.
That said, many brands offer diet or reduced sugar juices that are lower in carbohydrates. These products are packaged similarly to the full-calorie versions, so Israetel says you’ll need to read the nutrition label to ensure your juices are really low-carb.
Can you drink tea and coffee on the keto diet?
Yes. Plain, unsweetened coffee and tea served black are keto-friendly. If you drink your coffee with milk, however, that may be a problem, as one cup of whole milk has almost 13 grams of carbs. If you’re on the keto diet, Israetel recommends using heavy cream. A tablespoon has less than one gram of carbohydrates. There are even new, flavored creamers specifically for people who miss flavored coffee or tea on the Keto Diet.
Can you drink soda on the keto diet?
No, but diet soda is OK in moderation. Unsurprisingly, regular soft drinks are out, as a single 12-ounce can of Pepsi has 41 grams of carbohydrates. If you want to satisfy your soda craving, you’ll have to opt for diet sodas, which use artificial sweeteners.
According to Israetel, the fake sugars won’t knock you out of ketosis. But he does say that artificial sugars, in addition to raising numerous health concerns, may trigger cravings that cause people to eat more. Numerous studies in insects and mice have linked overeating to consumption of synthetic sugars, presumably because the substance triggers cravings for more sugar, Scientific American reported.
Can you drink booze on the keto diet?
Not really. Hardcore keto followers may want to avoid happy hour altogether, as alcohol “stops fat loss dead in its tracks,” Israetel says. Drinking alcohol temporarily bumps you out of ketosis, and it’ll also mean that you’ll get drunker faster, so you have to be careful.
Don’t want to give up booze, but still want to burn fat? Beer and wine are high in carbs, so you’ll want to stick to liquor, like vodka or whiskey, and drink it on the rocks. Going out for cocktails will also prove difficult, but you can easily make a low-carb mojito or margarita at home.
Can you drink protein shakes on the keto diet?
Yes. Protein shakes are an easy on-the-go breakfast for keto dieters who can’t just pick up a smoothie. In fact, Israetel says chocolate protein powders make a great addition to coffee if you’re used to picking up a mocha on your way to the office.
Of course, not all protein powders are low in carbohydrates, so you’ll have to check the label. Israetel recommends a powder that contains casein protein, which is digested slowly to help you stay full longer. Or, you could try a protein powder formulated to be nearly carb-free for keto dieters.
