The human body is an amazing machine. Capable of:
- Climbing mountains,
- Adapting to environments as disparate as the arctic and the tropical rain forest.
- Running for hundreds of kilometres at a stretch,
- Lifting freakishly heavy weights.
- Amazing technological advances,
- Creating art that can elevate the soul
Unfortunately, what your body can’t do is consume junk food – aka the Standard American Diet – without starting to fall apart.
Here’s the science:
According to this new study, after just 5 days of eating a diet that included sausage biscuits, macaroni and cheese, and food loaded with butter, healthy college-age students experienced a significant change in how their muscles processed nutrients. And not for the better.
According to the researchers, eating a starchy, fatty diet disrupts how your muscles metabolize glucose, “which could lead to the body’s inability to respond to insulin”, leading to insulin insensitivity, type 2 diabetes, metabolic syndrome and a reduced quantity & quality of life.
NOTE: In the study, the test diet was designed to have fat make up 55% of the calories – as opposed to a “normal” 30% fat diet – with the inclusion of foods such as sausage biscuits and mac & cheese. And while I agree that a diet in which 55% of the calories comes from fat can be called a “high-fat” diet, I would argue that it would be more accurate to call it a “high fat AND carb” diet or a “high fat AND starchy carb” diet or a “high fat AND high gluten” diet.
To infer that fat is the villain here may not be wholly accurate. We need a bit more research before we start blaming a single macronutrient.
What does this mean to you?
- As yummy as sausage biscuits smothered in gravy and bacon smells, you may not want to eat it very often. Your body hasn’t evolved (devolved) to handle this type of food.
- If you can’t resist the siren song of Mac ‘n Cheese, space it out with some healthy food, like a Big Salad, to help your muscles sensitive to insulin.
