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.
SlimFast Keto can be purchased through their Official Site.
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
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.
Erythritol is a sugar alcohol.
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.
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.
Benefits & 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.

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.
Pros & Cons
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
“At first it was hard to mix, but I gave it a shake it all blended together nicely, I added frozen blueberries and chia seeds with unsweetened almond milk!”
“I’m going to have to seriously doctor up the rest of the canister to make it drinkable…maybe add unsweetened coconut milk and a couple of frozen strawberries. Mixed with water, as per directions, it tastes artificial with a weird texture. The brownie batter flavor was at least drinkable. And only 8g of protein??? Not impressed…”
“The taste is good. I use it as snacks between meals. You may want to eat more than one during one break. I received two packs and most of them were melted before. Still edible though. If not on sale, the cost per pack is a little pricey.”
