There is no question that Keto works. It’s a strict high-fat, low-carb approach that denies the body glucose as a main source of energy, and instead promotes the production and use of ketone bodies as fuel.
Keto is a great way to move off a weight plateau, gain willpower, and get results fast. But going Keto also often results in gastrointestinal discomfort, low energy, and moodiness—known as the “Keto Flu”—which makes it unpleasant, and hard to sustain.
