But a metabolic flexibility eliminates carbs sparingly, at times throughout the day where it makes the most sense, and at other times, fat. The standard American diet (academically abbreviated to SAD, too real) is high in “red meat, high-fat dairy products, processed and fast foods, refined carbohydrates, added sugars, salt and calories.” A lot of crap, basically, and the body gets used to burning it. Your body should always be ready and willing to make use of whatever fuel’s available to it, which, ideally, would include fat in addition to carbohydrates.

They plug into charging stations, and they can run on biodiesel or ethanol. Excuse the overused automotive analogy, but today’s most efficient cars don’t rely entirely on petrol. It might help to associate your metabolism with a different quality: flexibility. There isn’t much you can do about your resting metabolism, and if you’re hoping to lose weight, attempts to speed up your metabolism through stringent dieting or excessive exercise often turn out to be self-defeating. These personal perceptions are blindly accepted as relevant to nutritional choices, workout regimens and general weight loss strategies.īut as Harvard Health Publishing points out, that speed or lack thereof (expressed through one’s basal metabolic rate), is largely genetic. As in: so-an-so can eat whatever he wants because he has a fast metabolism.

We’re used to speaking colloquially about the speed of metabolisms.
