The New Lean for Life

The New Lean for Life weight-loss program claims to retrain brain, body and gut to "think and act lean." Built around the principles of a ketogenic plan that is very low in carbohydrates, the diet is organized into a four-phase process: three days of preparation, 28 days of rapid weight loss, 14 days of recalibrating the metabolism, and a maintenance program. The book also emphasizes the latest research on the role of gut bacteria in weight management. The authors promote Lean for Life products, including supplements, and online programs.

While the meals are fairly easy to plan based on the recommendations, which include shopping guides and suggestions for vegetarians, the diet focuses on protein-rich foods at the expense of nutrient-rich foods — such as fruits, vegetables and legumes — that enhance healthy gut flora and promote wellness.

The New Lean for Life includes some helpful tips for weight loss and packages it in a structured program that reinforces long-term behavior and dietary changes. However, ketogenic diets are difficult for many people to adhere to and the diet doesn't provide for the variety of vitamins, minerals, antioxidants and other beneficial substances found in a plant-based diet, which is beneficial for weight management and for long-term health.
