Losing body fat, enhancing athletic performance and changing body shape are all by-products of optimum health, and optimum health can only be achieved via an optimum approach to nutrition.
To create and maintain optimal health requires a variety of nutrients from a range of nutritional sources.
But many people tend to eat a restricted variety of foods – with their choices including no more than 3-7 different food selections for the entire week. For example, chicken, beef, broccoli, and rice, and maybe a small handful of others.
But this type of limited eating can short-circuit your progress to optimum health and body shape.
Why eat more plant foods?
A high intake of low-energy, plant food carbohydrate sources at every meal essentially “tricks” the metabolism into staying elevated and promotes the permanent loss of unwanted body fat.
This process is where you are working with your metabolism and not against it.
Also, nutritional science is only just beginning to uncover an array of powerful, yet little-known compounds that protect our health from disease and many age-related ailments.
These compounds, called phytochemicals, occur naturally in whole plant foods and play an intricate role in achieving optimum health. But processing can destroy or remove these precious compounds.
These low-energy carb sources promote steady blood sugar and insulin levels.
This means no energy slumps during the day, more efficient metabolism of fat and effective nutrient transport into hungry muscles. All of these aspects add up to one thing; a stronger, leaner, healthier body.
But which plant foods are the best?
When in doubt about what plants to eat, aim for variety in color. To put it simply and to make it easy to remember, eat all the colors of the rainbow. The brighter and richer the color, the more nutritious the plant food is. Do a quick glance before each meal, look at your plate and determine how colorful it is.
Each color of fruit and vegetable has unique nutritional benefits that are important to your health.
And there are individual compounds within plants of different colors that may contribute to improving various aspects of human health, also known as phytochemicals.
These compounds can work synergistically to promote overall health, so remember to eat across the categories for the most benefit!
