What is KetoFast?

KetoFast is a book that promotes strategically timed fasts to encourage weight loss, reduce oxidative stress, optimize brain function, reverse insulin resistance, prevent neurological deterioration and stop inflammation in its tracks.

By combining fasting with the ketogenic diet, dieters will reduce visceral fat, lower blood pressure, improve cholesterol levels, prevent cancer and reduce the risk of heart disease and diabetes.

How Did KetoFast Start?

Dr. Joseph Mercola wrote KetoFast. Dr. Mercola is a controversial physician who sells a variety of alternative medicine supplements. Unfortunately, it seems like he has gotten in some trouble with the Food and Drug Administration.

The FDA recently ordered Mercola to stop making illegal claims regarding several products he sells on his website.

Despite several publicized controversies, Dr. Joseph Mercola has a considerable fan base. The University of Illinois educated doctor has authored several books and is a member of the Association of American Physicians and Surgeons. He often criticizes the overuse of medication and surgeries. He advocates for patients’ rights and the use of homeopathy.

Does it Work?

Does KetoFast Work?

KetoFast promotes both ketogenic eating and fasting to optimize health. There is some science to support both methods. A ketogenic diet requires eating very low carbohydrate meals to put your body into a state of ketosis.

Ketosis is the metabolic state that occurs when the body breaks down fat for energy. One study published in the Journal of Nutrition and Metabolism suggests a keto diet can help you lose weight while preserving muscle mass.

However, there are health concerns associated with a ketogenic diet. Harvard researchers found that a ketogenic diet can cause kidney problems, nutrient deficiencies, liver problems, mood swings, confusion and constipation.

Fasting is another weight loss method that is rapidly gaining popularity. One study published in the Journal of Clinical Investigation suggests that intermittent fasting can increase growth hormone secretions, and another study published in the American Journal of Clinical Nutrition concluded that fasting could improve insulin sensitivity.

There’s evidence that fasting can help you lose weight, but there are also concerns that fasting can be dangerous to your health. One study published in BMC Complementary & Alternative Medicine found that water-only fasts should only be done under medical supervision, as some individuals may experience adverse effects.

KetoFast Benefits and Results

We took a look at the reviews from verified KetoFast customers. The results were mixed. Some readers were disappointed that there wasn’t a step-by-step guide or recipes for ketogenic meals to rejuvenate your health. KetoFast does not contain any information on meal planning or alternative health remedies. Some reviewers thought the book was repetitive and provided pseudoscience instead of evidence-based weight loss solutions.

Not all KetoFast reviews were negative, however. One reader called the book “clear, concise and informative.” Another verified purchaser thanked Joseph Mercola for changing their life through nutrition and toxin avoidance.

  • Back Pain

Bottom Line

The Bottom Line on KetoFast

KetoFast is an interesting read. Joseph Mercola has a unique perspective on dieting and using food to boost your health. Is it the revolutionary diet approach you’ve been waiting for? Probably not. There is no clinical evidence to support the claims made in this book.

Dieting doesn’t have to mean giving up everything you love. The most successful weight loss programs focus on moderation. Eating a balanced diet and exercising regularly will help you lose weight. Finding a diet supplement that helps you along the way dramatically increases your chances of success, but with so many scams on the market, how do you know which supplement to choose?

We're all about exercise for a healthy, long life, but there's more to weight loss than burning calories. There's a place for supplements in some people's daily regimes, and supplement efficacy is growing.

Among the best supplements we've seen this year is called Burn TS. The formula is made up of four ingredients, and research shows the ingredients may support metabolism, improve hunger control, and promote increased weight loss. The makers didn't just pick the ingredients out of a hat – hundreds were reviewed, and only the best of the best made the cut.

When the company found out people were reporting results in as little as 14 days, they decided immediately to offer multiple-bottle discounts of Burn TS, a no-questions asked money-backed guarantee and also offer discounted bottles on Amazon.
