When on a strict diet (low carb or low fat), I heard that sometimes people find it hard to recollect things, even things they were thinking about a few minutes ago.
One instance, you might be going out so you know that you need to get your sunglasses, and by the time you reached reach your closet (say, in about 20-30 seconds) you forget what you were supposed to get.
Is this common?
One of the low-fat diet risks include poor brain function, because the brain basically requires a high amount of cholesterol, which can be reduced by low levels of healthy fats in the ration. Here's some more information about short term memory loss and some foods should be included in the diet to prevent it.
Connection between memory loss and nutrition:
Another cause of this problem is when you have a deficiency of certain vitamins in the body. If you don’t eat well then this can lead to deficiency of certain nutrients in the body such as vitamins that play a major role in keeping your brain in good health.
