Optavia is a popular meal replacement shake designed to help you feel fuller, and curb your hunger.

But if you can’t get hold of it, or don’t get on with it, you can substitute a Slimfast or Huel Protein Powder shake, or protein bars such as Kellogg’s Special K, RXBAR, or WonderSlim meal replacement protein bars.
Optavia fueling and shakes are super convenient for anyone who wants to look after their physical health.
You don’t have to buy lots of different ingredients or take the time to prepare or cook a meal. You get all the nutrients for an entire meal in just one meal replacement shake.
And it’s portable too, which is perfect if you’re on the go and have a busy day. All you have to do is add a little water or milk, give it a good shake, and you’re all set.
They’re designed to be high in both protein and fiber, while being low in sugar. They’re also kosher and lactose-free, and contain no artificial sweeteners.
This means that they’re great for both slimmers and body builders alike.

What Does Optavia Taste Like?
One of the things that makes Optavia Fueling and Shakes so popular is its wide range of different flavors. Bringing you all the variety you could want in your diet.
There are 7 different flavors available in total, including creamy chocolate, caramel macchiato, mocha, creamy vanilla, rich dark chocolate, peanut butter, and wild strawberry.
Most people take these shake mixes with water, but provided that you’re not lactose intolerant any one of these mixes can be mixed with milk, for an even creamier taste and texture. So long as taking milk with it suits your nutritional requirements, of course.
Many people also add in one or two extras on occasion, such as blended fresh strawberries with the strawberry shake, or a shot of espresso in the caramel macchiato shake, or some healthy nut butters in the chocolate shakes.
What’s more, you can enjoy the shakes either hot or cold – so many possibilities!

Optavia Substitutes
Huel Protein Powder
Huel Protein Powder makes for an excellent meal replacement shake because it meets all the USDA’s Dietary Guidelines and Daily Value (DV) requirements for all macro- and micronutrients, thanks to its balanced macro split of 37:30:30:3 of net carbohydrate, protein, fat, and fiber, as well as 27 essential vitamins and minerals.
It’s available in a great range of different flavors, including banana, salted caramel, chocolate, vanilla, berry, cinnamon swirl, coffee and mint chocolate.
It is primarily aimed at body builders however, rather than slimmers, because it provides considerably more calories and protein than alternatives such as Optavia, which suits the target market of Huel protein powder, who will use up those calories at the gym or on their workouts.
Slimfast Shake
Slimfast shakes, as the name implies, are especially formulated for anyone who wants to slim down.
One serving provides all the nutrients of a healthy balanced meal, and is an excellent source of protein and fiber, complete with 23 different vitamins and minerals.
And it also happens to be free of artificial colors, flavors and preservatives.
It’s available in 9 different flavors in total, including chocolate, vanilla, strawberry, banana, caramel, café latte, blueberry, and raspberry and white chocolate. Plenty of variety for your taste buds!
You can use Slimfast shake powders in the same way as you would Optavia, by simply adding water and giving it a good shake. And occasionally you can also find Slimfast shakes ready-made.
Kellogg’s Special K Protein Bars
If you don’t have time to make a shake, then Kellogg’s Special K Protein Bars make an excellent alternative to Optavia meal replacement shakes.
They’re not too high in calories or carbs, and they’re an excellent source of protein and fiber.
What’s more, coming from Kellogg’s, you already know they’re gonna taste great. They come in a great range of different flavors, including strawberry yogurt, cookies and cream, and chocolate peanut butter.
RXBAR Protein Bars
RXBAR Protein Bars are another great alternative to Optavia meal replacement shakes, because they are packed with flavor. I can highly recommend the chocolate sea salt flavor, for example.
There’s also blueberry, peanut butter, berry, chocolate coffee, cinnamon, and pumpkin spice. And they have an excellent texture as well, chewy but not too dense.
They’re reasonably low in calories, but at the same time, they also provide a great amount of protein and fiber to keep you satiated and satisfied until your next meal.
WonderSlim Protein Bars
WonderSlim protein bars are an excellent alternative to Optavia Fueling and Shakes because they’re incredibly slimming due to the low number of calories per bar, and low volume of fats and carbs.
It also features a staggering 23 different vitamins and minerals as well. And it’s both kosher and vegetarian to boot.
They’re available in a great selection of flavors, including chocolate cream, chocolate salted caramel, mocha cream, cocomint cream, strawberry cream, vanilla cream, and dark cocoa cream.

Popular Recipes That Call For Optavia
While there are so many people who rave about Optavia recipes, these are recipes that come from the Optavia company and not recipes that feature Optavia Fueling and Shakes as an ingredient.
Optavia Fueling and Shakes are shakes intended for use as meal replacement, so they are designed to be sufficient for an entire meal, with no other ingredients included other than water.
That said however, and as mentioned earlier, Optavia shakes can also be made with additional ingredients added in, such as milk, fruit or nut butters.
There are few set recipes around for this, and people simply just add in anything they think will either enhance the taste and/or texture, or add to the overall nutritional value.
Conclusion
In summary, there are some great food and drink choices out there that you can easily substitute in place of Optavia Fueling Shakes, such as a Slimfast or Huel Protein Powder shake, or protein bars such as Kellogg’s Special K, RXBAR, or WonderSlim meal replacement protein bars.
As for which to choose on any given day, this boils down to two main questions. Are you hungry for a shake, or a snack bar? And, is your aim to slim down, or to bulk up?
