When we seek to get into shape, we inevitably undertake a combination of strategies that result in a restriction of calories, including reducing food intake or seeking ways to burn more calories through exercise. Ultimately the intent is a calorie deficit. Over time, assuming we are consistent in the application, we lose weight, and if we maintain this discipline, it stays off too. Simple enough.
We also know that not all food provides the same nutritional value nor aids in powering our brains equally. For example, a diet of burgers, fries, and milkshakes is not the same as one laden with vegetables, light proteins, and healthy carbs. Of course, both are food sources, but proper nourishment is required to be at our best. So toss out the wrong choices while maintaining a complement of vibrant fresh, natural produce. Sound familiar.
The same applies to people. Like food, some people will nourish us and give us energy and may inspire us to greatness. Therefore, being selective with our people diet is essential. Surround yourself with a few good people who can inspire and motivate you, who become your sustenance, and enable you to flourish while eliminating and restricting those who deplete your energy. The principles are the same. Apply them and enjoy your leanness.
