“The short answer is yes,” says Marisa Moore, R.D.N., a registered dietitian nutritionist based in Atlanta. Here’s proof: Participants in aDiabetes Spectrum study who replaced two meals a day with a shake, hot chocolate, or soup lost 7.8 percent of their body weight after three months. The group with more leeway over what they ate lost just 1.5 percent of their body weight while consuming the same amount of calories.
Another analysis from the International Journal of Obesity and Related Metabolic Disorders reviewed studies that compared reduced-calorie diets with those heavy on liquid meal replacements. Both groups lost weight at the three-month and one-year marks, but the meal-replacement group lost more.
These seven R.D.-approved tips will help ensure that you’re actually seeing results (there’s more to it than: open shake, drink shake):
Pay attention to that nutrition label! The grams of protein in your shake should always be higher than or equal to the amount of carbs you’re consuming, says Jamie Mass, R.D. “This prevents your blood sugar from dropping and keeps you full longer,” says Mass.
If you’re short on protein, add a side of nuts, deli turkey, or a hard-boiled egg, she says. Or, if your shake has less than 10 grams of carbs, feel free to add a piece of fruit.
When you’re glued to your desk and don’t have time to grab lunch, shakes can be a healthy, convenient option, says Rob Sulaver, a certified sports nutritionist for BandanaTraining.com. Keep a stash in your work fridge for those days when the vending machine is your only other choice.
“People really struggle to get protein at lunch, so drinking a shake that’s rich in that nutrient with a small salad can be ideal,” says Mass. Just make sure that your shake clocks in at around 200 calories while your salad contains about 200 to 300 max, so you don’t go over your calorie budget for that day, she says.
Drink half of a meal-replacement shake 30 minutes before hitting the gym, then down the rest afterward, says Mass. If you’re working out during your lunch break, this is a great way to make sure you’re fueled and full.

You can also try this strategy while heading to the gym after work. That way you won’t be too ravenous post-sweat to whip up a healthy din, says Mass.
You can soothe your ice cream cravings by blending a shake (or half of one) with ice and vanilla extract, says Mass. You won’t miss the sugar crash that comes with a pint of B&J.
