Plant-based diets have been shown as one option to improve overall health. While some studies have shown that plant-based diets may have associations with certain health benefits, there have been no definitive causal links associated.

Smith outlines the following benefits of plant-based eating:

- Lower your cholesterol and blood pressure

- Reduce risk for heart disease, cancer, stroke and diabetes

- Help with weight loss

- Increase energy

- Boost your mood

While animal products can serve as a great source of protein, Smith says that people can still get those nutrients in a plant-based diet by eating more beans. This can include black, kidney, white, lima, chickpeas, edamame and more.

Smith's book also seeks to help people looking to lose weight by sharing a four-week plant-based plan. Each day the book details how to flip ones diet from 70% meat to 30% meat and 70% plants, which he said leads to natural and pain-free weight loss to keep people full and satisfied.

While the \"Plant Power\" plan is not specifically geared to be a weight-loss plan, medical experts believe if a reader follows it closely and pay attention to portion sizes, there's a chance someone could lose weight.
