Research on animals also suggests caloric restriction reduces neurological damage after a stroke, but only on young or middle-aged animals. Older animals do not appear to benefit, indicating that caloric restriction may offer stroke benefits only at certain points in life, Mattson said.
Caloric restriction may also help prevent Alzheimer's disease. Just as exercising benefits your muscles, "exercising your nerve cells does the same thing," Mattson said. Reducing daily calories puts stress on the brain cells that, in a sense, exercises them, Mattson said.
In mice designed to develop Alzheimer's disease, those fed a calorie-restricted diet performed better on memory tests, and had reduced levels of amyloid beta protein in their brain compared with mice not fed a restricted diet. Amyloid beta aggregates in the brains of patients with Alzheimer's disease, and is thought contribute to disease onset.
Caloric restriction has been showed to increase levels of a protein in the brain called BDNF. This protein is thought to be involved in the generation of new brain cells, Mattson said.
