Weighing 20 popular diets on the scale of science

Have you ever found yourself glancing longingly at that celebrity’s juicer machine ad, not for the machine but for that perfect body shape? Between the daily grind (of the juicer machine called “life”), busy professionals like us are constantly in touch with trendy diets for achieving that beach body.

From keto to paleo, there are just so many options, each promising weight loss and wellness. But with so much conflicting information out there, how do you know which one is right for you? Buckle up, because in this article, we’ll be diving into the world of popular diets, exploring their pros, cons, and everything in between. Let’s find your perfect fit, (if there exists any!)

The science behind popular diets

Macronutrients, comprising carbohydrates, proteins, and fats, play pivotal roles in our overall health and fitness journey.

Carbohydrates serve as the body’s primary energy source, fueling our daily activities and exercise routines. Proteins, on the other hand, are essential for muscle repair and growth, aiding in post-workout recovery and strength development. Fats, often misunderstood, are crucial for hormone regulation, cell structure, and nutrient absorption.

Each popular diet manipulates these macronutrients in different ways to achieve specific goals.
