Slimfast Keto: another well-known company on the keto train? For over forty years, SlimFast has produced weight loss products like nutritional bars and meal replacement shakes.

SlimFast Keto provides a plan to support dieters who wish to try a ketogenic diet. Along with a sensible diet and regular exercise, the program claims that dieters can see results in one week.

Our research team wanted to look into the SlimFast Keto products to determine their overall effectiveness as part of the ketogenic diet, including ingredients and clinical research. The research team found lots of information, including some things you’d never guess about the keto diet.

What is SlimFast Keto?

The SlimFast Keto line provides products for consumers on a high-fat, low-sugar, low-carbohydrate ketogenic diet. The keto diet is to keep users in a fat-burning state called ketosis.

SlimFast Keto products include keto smoothies and bars and keto-compatible supplements. SlimFast claims that following their low-carbohydrate diet plan will provide some benefits, including rapid fat burning, hunger suppression, and ability to eat foods like bacon and steak.

Slimfast Keto makes a lot of claims, but are any of them true? Before delving into this keto product line, let’s review what the science has to say about this kind of diet and some of the ingredients found in Slimfast Keto products:

• Experimental and Clinical Cardiology – Research found that on a ketogenic diet, the weight and body mass of obese patients “decreased significantly.”
• Medical News Today – MCT oils such as coconut oil may help reduce obesity in mice.
• Obesity Research Some research suggests MCT oils allow the body to generate more energy, which gives dieters more room to eat satisfying proteins.

How Did SlimFast Keto Start?

SlimFast has been in business since 1977, focusing on SlimFast diet pills, shakes, snacks, prepackaged meals, and other products for managed weight loss. SlimFast also provides meal plans to help consumers attain their health goals.

In 2004 in response to demand for low-carb products, SlimFast first produced the lower-sugar SlimFast Optima line and recently introduced SlimFast Keto products for the needs of a ketogenic diet.

SlimFast Keto Claims

SlimFast Keto products claim to help keep dieters in ketosis. While the official site acknowledges no “magical, quick-fix cure for weight loss,” a low-carbohydrate keto diet such as the SlimFast diet plan can play a significant role in weight loss.

The SlimFast Keto Diet also claims a ketogenic diet will help reduce hunger pangs by suppressing hunger hormones and allowing dieters to eat satisfying foods like steak.

SlimFast Keto Ingredients

SlimFast Keto products include meal replacement shakes, snacks, and dietary supplements. All of the products provide low-carbohydrate, high-fat nutrition.

Some key SlimFast Keto ingredients include:

• MCT Oil Blend (palm, coconut, grass-fed butter)
• Protein Blend (whey protein concentrate, whey protein isolate)
• Grass-Fed Collagen Peptides
• Cocoa
• Erythritol

MCT Oil

MCT Oil is an oil made of medium-chain triglycerides (MCT) that commonly occurs in coconut oil. MCT oils help raise the fat content of SlimFast Keto products and help promote a feeling of fullness.

When a part of a weight-loss diet, MCT oil may lead to more weight loss than a diet supplemented with olive oil, according to the American Clinical Journal of Nutrition. 

Erythritol

Erythritol is a sugar alcohol. Erythritol is a modified form of sugar that does not raise your blood sugar level, according to the European Journal of Clinical Nutrition. 

Stevia

SlimFast Keto products frequently feature a natural sweetener called Stevia. Although stevia is 300 times sweeter than standard sugar, it has a limited caloric impact and has been used in foods in Japan since the 1970s.

According to The Journal of Nutrition, stevia is popular due to it being plant-based, zero calories, and significantly sweeter than sugar.

Whey Protein and Collagen Protein

Whey and collagen protein enable cells to rebuild themselves, which is especially important in conjunction with a healthy exercise program, as the SlimFast diet plan recommends.

According to Frontiers in Pharmacology, whey protein may be beneficial to exercise recovery in athletes.

Does SlimFast Keto Work?

Any diet or exercise plan has variable results depending on a person’s health and general commitment to the program. However, as the International Journal of Environmental Research and Public Health points out, the ketogenic diet tends to be useful for different reasons:

• Control of appetite hormones
• Appetite-suppressant effect of ketones

The SlimFast Keto diet, designed to maintain ketosis, can help dieters achieve these results.

SlimFast Keto Benefits and Results

SlimFast Keto results will vary. The products function to put dieters in a state of ketosis. In ketosis, the body uses fat to produce ketones, which are small molecules used for energy.

In short, an essential benefit of the SlimFast Keto diet plan is that your body will burn its own stored fat to power you. The results of a long-term ketogenic diet are unknown.

Details on SlimFast Keto and Weight Loss

An important aspect to understand about this keto diet plan is that dieters replace two daily meals with SlimFast products, including shakes, bars, or cookies, to reduce hunger and maintain the metabolic rate at a higher level.

For optimal weight loss, the SlimFast diet strongly advises dieters to avoid sweetened beverages and sweets in general. SlimFast Keto results depend on keeping sugar and carbs to a minimum.

Weight loss is more likely to occur when dieters keep themselves in a ketogenic state. Sugars or excessive carbohydrates will make the body “switch over” from burning fat to burning the carbs in food. This will cause weight loss to slow down, or more likely, reverse, so you gain weight.

How to Use SlimFast Keto

SlimFast Keto products can be used individually on an as-needed basis by dieters wanting an occasional low-carbohydrate snack or meal replacement shake. Additionally, SlimFast products can form an essential part of an overall health program.

One to two meals a day can are the SlimFast shakes, bars, or snacks. The final meal of the day can follow recipes or suggestions on the SlimFast keto diet program. Ideally, the meal should be higher in healthy fats, adequate in protein, and low in carbohydrates.

How Much Does Slimfast Keto Cost?

The official SlimFast website does not list prices for its items. Is SlimFast Keto on Amazon? Yes, and the products are easy to find. Some representative costs of specific SlimFast Keto products are as follows:

• Keto Meal Replacement Peanut Butter Fat Bomb: $9.97 per box
• Keto Meal Replacement Bar: $9.97 per box

Potential SlimFast Keto Side Effects

Potential SlimFast keto side effects can vary. Medical News Today points out that especially if dieters are new to ketosis, they may experience sluggishness, constipation, or low blood sugar.

Other keto dieters experience what is known as “keto flu,” a general feeling of lowered energy as your body adjusts from burning carbs to burning fat. Keto flu is treatable by drinking water with electrolytes.

SlimFast Keto Pros and Cons

SlimFast Keto products, if used as part of an overall health management program and regular exercise, may help dieters lose weight. Weight loss in a low-carbohydrate plan usually happens quickly before some degree of plateauing or tapering.

One downside to the SlimFast program may be the limited number of products available through the SlimFast Keto line. As Harvard University states, a low-carbohydrate diet can be challenging to stick to in the long run. Lack of food variety may cause dieters to lose interest.

What Users Are Saying

“This shake mix is delicious! I used to do the regular shakes on the non Keto line for Slim Fast. I know the Slim Fast diet works for me. I was excited to try this along with my Keto diet. The flavor is delicious! I have made it with water and unsweetened almond milk and both taste great! I usually make one for breakfast with just some unsweetened almond milk and give it a good shake it sometimes can be a little lumpy but that doesn’t really bother me. Now when I make this for dinner I put the almond milk a handful of ice cubes and blend it in my Ninja Blender so it comes out thick! I’m telling you its the best way to have this shake it tastes like a Wendy’s Frosty! Buy the powder and not the pre made shakes! The pre made ones will give you an upset stomach!”

“Get Atkins Bar Instead. This is one if the most tasteless…well, bad tasting products from Slim Fast I’ve consumed. The nutty part was extremely chalky, the chocolate tasted processed and it had no substance to it. Very disappointing, Slim Fast. I can’t see how this would be considered a meal replacement.”

“Honestly made me feel wicked gassy… tasted amazing but something in it killed my stomach!”

Bottom Line on SlimFast Keto

The SlimFast Keto line claims that dieters can lose weight with a minimal amount of hunger pangs or cravings by using SlimFast Keto products as part of an overall weight management plan in combination with exercise.

We’re all for moving toward a healthier life, but sometimes, it can be hard to make those lifestyle changes needed. Luckily, clinically-proven programs exist to make the transition a whole lot easier.
