11 Best Meal Replacement Shakes for Weight Loss, According to Dietitians

Unlike some protein drinks, smoothies, or juices, which are more like low-calorie snacks, meal replacement shakes are designed to stand in for your entire breakfast, lunch, or dinner. They should meet similar nutritional standards as a solid meal in terms of calories, carbs, fat, and protein. While we wouldn’t recommend replacing all of your meals with these supercharged sippers, they’re a convenient option to reach for on busy mornings or whenever you need to grab something on the go.

If you’re thinking these shakes are an effective diet solution, know this: Whole foods like grains, fruits, vegetables, and proteins contain beneficial nutrients and compounds that can’t be replicated in a ready-to-drink package. Rather than a healthy hack, these drinks are a way to shore up nutritional deficits or keep your body revving when back-to-back meetings or errands prevent you from sitting down for something more substantial. “If you’re an athlete or very active and require more calories and protein throughout the day, they can also be useful to meet your nutritional needs,” adds Amy K. Fischer M.S., R.D.N., C.D.N., a registered dietitian and contributing writer at the Good Housekeeping Institute.

Before slugging one back, it’s important to check nutrition info and ingredient labels. Many of these store-bought drinks are high in sugar and don’t have enough protein or calories to constitute a real meal—let alone keep you full until your next nosh. Additionally, most pre-made shakes aren’t regulated by the Food and Drug Administration (FDA), as they’re often considered supplements, so it’s a good idea to look for third-party seals that indicate they’ve been tested for quality.

How to choose (and use) meal replacement shakes

Check the calorie content. In reality, having a meal replacement shake on its own isn’t enough. “The number of calories needed per person varies greatly depending on factors such as height, weight, activity level, age, and health goals,” explains Fischer. “Some adults might require only 400 calories per meal while others may require a lot more than 500 calories. Most meal replacement shakes usually fall in the range of 150-300 calories, so some individuals may need to supplement their shake with other food.”

Given that calorie content varies greatly from shake to shake, it’s important to pay attention to how many calories you’re consuming. There’s a big difference between a shake with 140 calories and a shake with 400 calories, so what you decide to pair with your shake may also need to be adjusted to meet your personal nutritional needs.

Check the protein and fiber content. Beyond just the calories in the shake, it’s important to pay attention to the nutrients as a whole. Protein typically varies from 15-40 grams per serving, and how much you need may depend on how active you are (athletes tend to need more protein than those who are inactive). Likewise, fiber and fat can help keep you full between meals, so drinking a shake with these nutrients can be beneficial. “While protein needs vary from person to person, look for a shake that contains more than 15-20 grams of protein, more than five grams of fiber, and 10-15 grams of unsaturated fat,” suggests Fischer.

Make it a meal. Remember it’s important to eat a balanced diet that delivers a wide range of nutrients from a variety of sources. A meal replacement shake may be able to check some of the boxes, but low calorie, fiber, or fat content may make it hard to stay full and energized all day. Depending on the nutritional content of the drink, make sure you add small, healthy snacks alongside it, like those suggested here. Easy, portable options include nuts, fruits, veggies, single packs of hummus, and hard-boiled eggs.

Can you lose weight with meal replacement shakes?

Weight loss depends on many factors, including total daily calorie intake. While it’s possible to lose weight with meal replacement shakes if you’re reducing your calorie intake to a level where you’re burning more calories each day than you’re consuming, it’s not a foregone conclusion. If you’re trying to lose weight, it’s important to talk to a registered dietitian to make sure you’re setting yourself up for long-term success, as most short-term diets don’t lead to sustained weight loss.

Is it okay to only drink meal replacement shakes?

As a general rule, no, you shouldn’t consume a diet that solely consists of meal replacement shakes. Fischer says, “Food first is always the best policy” and that meal replacement shakes are great for when you’re in a pinch but should be used sparingly. “I would not recommend drinking more than one a day except if there is an underlying reason, like a medical prescription,” she says.

Benefits of meal replacement shakes

While many meal replacement shakes do not offer enough calories to count as a meal, they do contain proteins, fats, and carbs, making them a good option to combat hunger—especially when paired with a nutritious snack.

Additional benefits, per the Mayo Clinic, include:

• Compensate for nutritional deficits
• Great source of protein
• Keep lean muscle
• Feel full
• Lower body fat
