Shakeology vs Slim Fast

Trying to lose weight and cut down some pounds from the body can be a tremendously difficult task for some people. Sometimes, even after you avoid certain foods that are known to easily induce weight gain and exercise regularly, you are still unable to reach the desired body weight. If that’s the problem, you can try replacing one of your daily meals and snacks with a protein shake. In the following article, you can read about two popular protein shakes, Shakeology vs Slim Fast.

Shakeology vs Slim Fast 1

Shakeology is now the most popular weight-loss shake on the market. It can be considered as a premium product, considering the price tag, but it is receiving lots of positive reviews regarding its performance. On the other hand, Slim Fast products are quite more budget-friendly, and they come with nice flavor options. So, can they really help you lose weight? If so, which one is better? Find out below!

Shakeology’s Products

Shakeology is a great product because, unlike many other weight-loss shakes on the market, it actually provides several flavor choices. The regular version is available in five flavor choices: vanilla, chocolate, strawberry, greenberry, and café latte. In addition, Shakeology also provides a vegan option, which is available in two flavor options, chocolate and strawberry. By the way, if you like vanilla and chocolate, you may want to take a look at Shakeology vs Thrive.

Although Shakeology provides a vegan version, it is not certified to be gluten-free, soy-free, or lactose-free. Well, it actually does not use any ingredient that contains gluten or soy (and the vegan version does not use whey, which contains lactose). But the product is manufactured in a facility that also processes allergens such as wheat, soy, and milk. So, if you are allergic to gluten, soy, or lactose, this needs to be considered.

Slim Fast’s Products

Slim Fast is a very interesting brand because it produces not only meal replacement protein shakes, but also low-calorie snacks. However, let’s focus on the protein shakes here. There are two lines of products, Original and Advanced Nutrition.

The Original shakes are available in cans (as powders) and in bottles (as ready-to-drink shakes). They come with five flavor choices: rich chocolate royal, creamy milk chocolate, French vanilla, strawberries &cream, and cappuccino delight. The last one is not available in cans. Meanwhile, the Advanced Nutrition shakes are available in vanilla cream, strawberries & cream, creamy chocolate, caramel latte, and mocha cappuccino.

All of Slim Fast’s shakes are certified to be gluten-free. The Original shakes, however, are not lactose-free. But you can mix the shake with a lactose-milk milk or low-fat soy milk in order to reduce the lactose concentration. Or, you can choose the Advanced Nutrition shakes instead, which are lactose-free.

Comparing the Taste and Texture

So, with all the available flavor choices of Shakeology vs Slim Fast, which one actually does taste better? Well, the answer to this particular question would be Slim Fast. Its flavor choices are quite unique, and it mixes pretty well in water. If you hate the idea of mixing a protein shake by yourself, you will definitely find the read-to-drink shakes awesome. And, again, they taste great, without clumping whatsoever.

Shakeology actually tastes nice. The vanilla and chocolate flavors are the best, and the café latte and greenberry flavors are fine. The strawberry flavor is not that great, the taste is somewhat artificial. But the biggest problem is mixing the powder. You want to use a blender in order to mix it well without clumping. You can also use the mixing bottle when you are on the go, but this method requires some extra effort. Without using a blender, you may find the powder clumps a little.

Nutritional Values

Now, let’s see the nutritional values of Shakeology vs Slim Fast. If you want to lose weight, you have to limit down your total calorie intake. Ideally, you should also stay away from too much carbs, sugar, fat, and sodium. Instead, you should focus more on protein and fiber; protein is a very good energy source during your weight loss battle, and fiber can make you feel full for a longer time.

Shakeology vs Slim Fast 3

Each serving of Shakeology contains about 140 calories, with just about 1 gram of fat, 17 grams of carbs, 9 grams of sugar, and 100 mg of sodium. The levels of sugar and sodium are pretty high, but still not too bad if you don’t drink it too much in a day. It also contains 17 grams of protein and 3 grams of fiber. Shakeology is enhanced with various vitamins and minerals to prevent cravings caused by insufficient vitamin or mineral intake.

On the other hand, each serving of Slim Fast contains 180 calories, with 5 grams of fat, 24 grams of carbs, 17 grams of sugar, 200 mg sodium. The protein content per serving is 10 grams, whereas the fiber content is 5 grams. You see, the tasty flavor of Slim Fast can be explained by the high sugar and sodium levels. But being healthy is a different thing than being tasty. In addition, if you are not careful to limit your calorie intake, Slim Fast will not help to reduce your weight – 180 calories are equivalent to regular potato chip snacks.

Appetite Blocking

The idea behind weight-loss protein shakes is getting something that can fill your stomach, and curb your appetite, without making you gain weight. This is also the question when choosing between Shakeology vs Slim Fast. Can they block your appetite? However, the two products have received mixed reviews. In general, they can indeed reduce your hunger for a few hours, making them suitable for snacks before the main meals. However, they are bad meal replacement shakes; you will feel hungry again within less than four hours.


In the end, we recommend you to choose Shakeology because the nutritional values are better. It has decent protein levels, and the total calorie is quite low. The sugar and sodium levels are also not as high. It can be a more effective solution for weight loss. On the other hand, Slim Fast is indeed tasty and very convenient, but the total calorie is higher and the sugar and sodium levels are too high.
