Don't go low-carb. There is no need, it's not unhealthy. Especially if you are sporty (as it sounds). The current state of affairs is: If you are insulin resistant (either because of genetics, obesity, whatever) then having a low-carb high fat diet is better for you. If your insulin resistance is high, then your pancreas produces much more insulin, meaning your cells will start storing energy instead of using it up. If this keeps up for a long period, your fat tissues, which are supposed to be your fat/energy storage, will fill up and your body (or rather the particles transporting the transformed sugar from the liver) will start sticking to your organs. This starts inflammations and makes your organs weaker, and in turn also raising your insulin resistance. And these malfunctions also spread to the brain and can cause alzheimer and the like. The exact chain of effects is not yet confirmed, so from here on it's a lot of speculation.
But if you now are trying to lose weight, and you just reduce calories, but keeping a "high-carb/low-fat" diet, then you will be hungry. Because either you have too little protein to feed yourself, or you eat enough protein and you automatically eat too many carbs again, producing more and more insulin.
This is how high-fat diets come in handy, as they don't spur liver activity and don't impact insulin as much. This in turn means you can reach ketosis, starting to work the fat on your organs (which is a lot more dangerous then some fat in fat tissues like your belly). Your body will recover, inflammation will go away and your insulin sensitivity goes up again (unless you are genetically diabetic). And with a healthy body your brain can also recover. The studies for this are still coming in, but I find this explanation very logic and even this study, although the article is weirdly phrased, plays into it. Some remarks at the end:
- If you do a lot of sports, your muscles use energy even without insulin
- Glucose is spread through the body, while fructose is directly converted to fat (tissue)
- Sport also increases insulin sensitivity
- Diets are very personal, try out things for yourself and see how it works!
- Protein is also increasing insulin (since protein intake signals the body to start storing energy, i. e. protein into muscle cells) |
