10 of the Most Popular Diets in 2023

With 4 out of 10 Americans following a diet plan, the company Ketolog has been busy analyzing trendy diets focusing on weight loss, health, and overall well-being.

Since we’re talking about health, let’s get the disclaimers out of the way. Let us start by saying the following information is not intended to replace information and guidance offered by your health care provider; and if you choose to follow any program, we strongly encourage you to speak with your provider. The information contained in this article is provided on an “as is” basis with no guarantees of completeness, accuracy, usefulness or timeliness. We should also note that while Ketolog is a keto-diet-based website, we felt the information provided by the survey results could be useful to our readers, whether they were fans of the keto program or not. We also encourage you to speak with your health care provider about an accompanying exercise regime that will work best for you. Pros and cons of each plan were noted by the Ketolog author, not 517 Magazine.
