Of course the lure of all-the-bacon-or-fat-you-can-eat was arguably behind the initial success of the Atkins diet that exploded into popularity in the '90s. It was followed by more low-carb options such as South Beach, Paelo, Whole30 and Zone, among others. Once all that passes, keto-lovers maintain, you'll have more energy, a more focused brain, and best of all, very little hunger.
It is several decades since the Atkins Diet rose to prominence – and I witnessed first-hand the weight loss some friends achieved on Atkins. And the ones doing the rounds at the moment aren’t the first or the only diets to do that. All you need to do is remove carbohydrate from the diet . But it turns out you don't need to starve yourself to get into ketosis. Our metabolism then switches to fat-burning, and converts stored fat molecules into ketone bodies that can power our muscles and brain because the glucose has run out.
And, as with any diet, it will only work if you are consistent and stick with it in the long term. It may be less suitable for elite athletes or those wishing to add large amounts of muscle or weight. Protein should be moderate, as a very high intake can spike insulin levels and lower ketones.
