1. The Mediterranean Diet

The Mediterranean diet is inspired by the traditional eating habits of countries bordering the Mediterranean Sea. It's renowned for its heart-healthy benefits and sustainable approach to weight loss.

The Mediterranean diet is inspired by the eating habits of people living in countries bordering the Mediterranean Sea. This diet emphasizes whole foods, healthy fats, and moderate protein intake.

2. The Ketogenic Diet

The ketogenic diet, or keto, is a low-carb, high-fat diet that aims to shift the body into a state of ketosis, where it burns fat for fuel instead of carbohydrates.

Key Features

Potential Drawbacks

  • Not suitable for everyone, especially those with a history of eating disorders.
