When I think about all of the motivations for eating healthy—promises of a longer lifespan, reduction in diseases, losing weight and looking better—the one that most appeals to me is improving my brain. If eating can help me remember things better and process information more quickly then I’m getting an immediate payoff and am therefore more motivated to select healthier food options. The other benefits of a good diet are more delayed and as a human living in an era of immediate gratification, I want results now. That’s why I titled this post about the brain because I’m hoping this will wake you up and motivate you to think about the food choices you’re consuming and whether it is going to help or hurt your brain NOW.
In short, fat is our friend. The brain NEEDS fat. Heck, the brain IS fat (at least more than half of it is composed of fat). So, doesn’t it make sense that it requires lubrication? Think about those poor nerves encased in a myelin sheath that never gets fed properly. It’s like a piece of leather left out in the sun. It dries out. It doesn’t work as effectively. Anyone who has ever read The Seal Skin story can apply that lesson here. (It’s a favorite story of mine and I’ve always wanted to reference it!)
The problem with fat is when we our arteries get clogged and health is risked by consuming it. For years, doctors have encouraged lowering fat when one has high cholesterol. Hundreds of beauty magazines have also encouraged low-fat diets for weight loss. We’ve been conditioned and we’ve seen the consequences. (This blog is inspired by the loss of my mother who lived on a low-fat, barely any calories starved existence for years until her metabolism was ruined and then she gave in and ate foods to sate her deprivated body...which led to losing her health and life to obesity and diabetes. That’s a dire consequence! Of course her body was starved and sugar was the quickest fuel, so her body naturally craved it.)
"Your body is either in glucosis or lipolysis."
Fat is not bad. Consuming fat with sugar is bad. To put it very simply, our bodies can run on two types of fuel—sugar or fat. When we consume higher carbohydrates, our bodies automatically pick the easiest fuel for energy—sugars (carbs), or glucosis. If we limit the carbs and consume fats, we can switch our bodies into lipolysis (fat-burning machines), which is what our bodies actually crave and run more efficiently on, like a fancy Lamborghini that needs high-end oil and fuel to operate optimally.
Numerous studies reveal a low-carb, high fat diet reduces weight loss, curbs health problems, and improves overall nerve and brain functioning—including easing mood disorders like depression. What’s exciting is that researchers are finally studying this issue in more depth and reporting on it. One recent study published in Annals of Internal Medicine even revealed that the low-carb, high fat diet produces decreased fat, increased lean body mass, and decreased inflammation (a huge component underlying so many diseases) among Caucasians and African Americans.
The takeaway is to feed your brain with healthy fats and decrease your carbs so that it will actually use the fats you ingest. If you have been living on carbs and sugars for a long time, it will take a little bit of time to heal from the withdrawals, yet you should feel increased energy after a few days.

Change your diet for two weeks and see how you feel. Sate your body with healthy fats and see how efficiently your brain works. Then post your results in the comments section. Looking forward to learning how it works for you! Blessed wishes and happy healthy eating!
