What is Fast Fit Keto?

What is Fast Fit Keto

Fast Fit Keto is a weight loss supplement that claims to help with the process of ketosis. The consumption of this supplement is often accompanied by a strict keto diet and physical exercise.

Fast Fit Keto claims it facilitates weight loss by helping the body to achieve a state of ketosis faster. The keto diet limits the intake of carbohydrates—the food responsible for energy production in the body. With reduced consumption of carbohydrates, the body’s supply of glucose—the main source of energy in the cells in also limited. As a result, people who are on keto diets often feel tired, which Fast Fit Keto claims to help with as well.

Getting the body to a state of ketosis while only relying on your keto diet can take weeks. The Fast Fit Keto supplements say they supply the body with external ketones, which helps boost the time frame of ketosis. Once the body has reached ketosis, it starts using the fat stored as a source of energy.

Before delving deeper into this supplement, our team took a closer look at the studies associated with some of the ingredients and a keto diet:

  • Metabolism: This study found that athletes who frequently exercised and switched to a ketogenic diet burned 230% more fat when they exercised than those who weren’t on the diet.
  • Journal of Special Operations Medicine: This research found that keto dieting and supplementation could not lead to the same benefits as a customized nutritional plan.
  • Nutrition Research: According to this study, more research is needed to determine the long-term effects of a ketogenic diet.

Fast Fit Keto Claims

Fast Fit Keto Claims

The claims Fast Fit Keto makes for its weight loss products are based on the fat-burning ability of a few of the critical ingredients, according to the product’s claims.

Other claims made about the product include:

  • Burns fat for energy
  • It helps you get into ketosis faster
  • Helps in weight loss
  • It helps in building stamina
  • Burns fat in trouble areas
  • Enhances metabolism
  • Faster recovery from exercise
  • Improves brain health
  • It helps maintain lean muscles

Fast Fit Keto Ingredients

On the website, Fast Fit Keto only lists BHB ketones as the primary ingredient in the supplement.

  • Calcium Beta-Hydroxybutyrate
  • Sodium Beta-Hydroxybutyrate
  • Magnesium Beta-Hydroxybutyrate

Does Fast Fit Keto Work?

The primary ingredient, BHB ketones, is also present in most commercial fat-burning supplements.

Beta-hydroxybutyrate (BHB) Ketones

Beta-hydroxybutyrate ketones are one of the three ketones that the body naturally produces during low carbohydrate intake or high-fat intake. When the body burns fat as a source of energy, BHB ketones are formed.

Exogenous ketones are ones found outside the body, according to research published in Current Sports Medicine Reports and Nutrients. These ketones often come in the form of ketone salts. These salts are bound to salts like sodium, magnesium, potassium, and calcium.

According to the Journal of Dietary Supplements, ketone supplements help increase blood ketone levels and mimic what happens in ketosis when you follow a ketogenic diet. Additionally, some research published in the Journal of Physiology and Biochemistry found that ketosis may play a role in decreasing oxidative stress.

When the body uses fat instead of carbohydrates as a source of energy, individuals may be able to reduce body fat and lose weight, though more research is needed in this area, according to Current Developments in Nutrition.

Weight Loss

Fast Fit Keto and Weight Loss

Fast Fit Keto claims their exogenous ketone supplements help induce fat burning in the body and prevent more fat reserves from being formed. Once users achieve this state, the product claims they can begin to lose weight and can keep the extra weight off for long.

Although there is some research showing ketones may slightly aid the body in entering ketosis, there is little evidence showing that these kinds of products have any effect on weight.

The primary ingredient present in Fast Fit Keto is also present in many commercial fat burners that have been scientifically proven to help burn fat and reduce body weight.

Side Effects

Fast Fit Keto Side Effects

There are no documented side effects that result from using the supplement. However, there are reports on the side effects of following a keto diet. These side effects include stomach upsets, bad breath, constipation, nausea, insomnia, diarrhea, vomiting, and dizziness, according to Nutrients.

Other common side effects of a ketogenic diet include dehydration, mineral deficiencies, anxiety, lethargy, and more, according to the Journal of Postgraduate Medicine.

There are certain precautions associated with the product that users should keep in mind:

  • It’s not suitable for persons under the age of 18
  • Don’t use it when you’re pregnant or nursing
  • Don’t use it if you’re already taking other medication
  • Don’t use it together with other dietary supplements

Additionally, individuals should consult their doctor before they begin using any dietary supplement.
