Best Meal Replacement Shakes of 2026

BOOST Original is the closest thing here to a no-decision meal replacement: 240 calories, 10 grams of protein, and 27 vitamins and minerals in a ready-to-drink bottle. The rich chocolate flavor is the one we reach for—it tastes like a treat without crossing into candy territory. We also appreciate that it skips artificial flavors, colors, and sweeteners, which is not a given in a shelf-stable shake.

What makes it our top pick is the balance. At 240 calories, it covers a light meal without weighing you down, and the micronutrient list makes it more than a protein drink with a vitamin pack thrown in. It doesn't try to be a workout shake, and that's the point: it's a practical lunch replacement for a desk day, a travel morning, or a skipped meal. The 24-pack is also the right format if you want to keep a few cold and stop thinking about lunch.

It is not the heaviest option in this group. If you need a bigger calorie hit or more protein, Ensure Plus is the better fit. For a chocolate shake that covers the basics and tastes good cold, this is the one we point to first. Give it a good shake and chill it well; the flavor is best when it's properly cold.

Fiber is the reason to look twice at Ensure Original. Most ready-to-drink meal replacements lean on protein and calories; this one adds fiber to a 9-gram protein, 27-vitamin-and-mineral formula. That makes it a better fit for a light lunch that needs to hold you until dinner—or a snack between meals, which is how the label positions it.

The vanilla flavor is mild and easy to drink, and the 24-pack is easy to stock in the fridge. We like it for the days when a full sandwich feels like too much effort but a protein shake alone won't cut it. The fiber gives it a little more staying power than the protein number suggests, and the micronutrient list is the same 27 you get across the Ensure line.

The trade-off is that 9 grams of protein is on the light side for a meal replacement, especially if you're active or using it after training. Fiber and dairy can also be a digestive adjustment for some people, so start with one bottle rather than a full day's worth. Chill it well and keep a bottle in the door shelf for the days you'd otherwise skip lunch.

Three hundred and fifty calories is the headline, and it's the reason to choose Ensure Plus over the standard Ensure. The bottle also carries 16 grams of protein and 27 vitamins and minerals, so it works as a higher-energy meal replacement rather than a light snack. Vanilla is the flavor in this pack, and it's mild enough to drink daily.

This is the pick for a low-appetite stretch or a weight-maintenance goal, when a standard shake leaves you hungry. The extra calories are the point, and the 16 grams of protein gives it more staying power than the 9-gram Original. It is still not a high-protein workout shake, so don't expect it to do the job of a dedicated post-training drink.

We see it as a targeted buy, not the default. If you want a light lunch, it's more than you need. If you're trying to get more energy into a small volume, the 350-calorie formula earns its place. The vanilla flavor is the right choice for daily use; it doesn't get in the way.

The math is the appeal: one canister makes 52 servings, and the powder format costs far less per meal than any ready-to-drink shake here. Each serving has 23 vitamins and minerals and fiber, and the chocolate version mixes into a thick, creamy shake. If you already have a shaker bottle and a fridge with milk, this is the most economical way to replace lunch among these picks.

The catch is the protein number. SlimFast lists 10 grams of protein when you combine the powder with 8 ounces of fat-free milk; mixed with water, you're getting a thinner shake and less protein. That matters if you're using it as a meal rather than a snack, so budget for milk. A shaker bottle or blender also earns its keep if you want a smooth texture.

We see it as the budget pick for someone who will actually prep at home, not a grab-and-go solution. The chocolate flavor is the reason it has stayed around; it's dessert-like without being too sweet, and the fiber helps it feel more substantial than a basic protein powder. For a routine you keep at the kitchen counter, it's hard to beat on cost among these picks.
