By now, you’ve likely heard of the keto diet, a high-fat, low-carb plan that many swear is the ultimate solution for fat loss. Its reputation is for being grueling, but rewarding; many devotees attest to it being one of the ultimate diet plans for transforming your body into a fat-burning machine. But is it all it’s cracked up to be, or is it the next diet fad just waiting to be discredited?
The science behind the method goes like this: if you eat next to no carbohydrates, your body will fundamentally change the way it burns fat. In the absence of carbs to turn into glucose, the liver turns dietary fats into fatty acids and burns them in the form of ketones. This can, in theory, have some profound effects on fat loss, though not without its drawbacks.
In general, the plan is considered extremely restrictive and presents a range of side effects, leading many people to quit before seeing any results. Considering that the best diet is one you can stick to, this might be reason enough to opt for something less drastic, like a well-rounded, whole foods-based diet that allows for healthy carbs, fibrous veggies, proteins, and fruits.
