When it comes to weight loss, diet is more important than exercise. Your body burns the majority of its calories by simply keeping you living and breathing. Burning additional calories, while still beneficial in many contexts, only marginally adds to your caloric total. It’s like taking a paper route when you have a $100,000/year salary.

At the lower end, adding additional exercise when you already have a reasonable diet structure through counting calories or mindful eating yields a lower return on investment (or ROI) on your time. Some may be fine with spending an extra few minutes eking out an additional caloric deficit, but it’s important to remember that we have limited amounts of time, energy, and—most importantly—willpower.
