I was watching Daniel Amen M.D. on TV about his new book. He is the brain doctor with the brain books. He says that the heavier you are, the smaller your brain is. This new book is Use Your Brain to Change Your Age: Secrets to Look, Feel, and Think Younger Every Day (Published February 14, 2012). Dr Daniel Amen is a board certified child and adult psychiatrist and a Distinguished Fellow of the American Psychiatric Association.
It tells about the different brain types that get overweight. It describes them as:
■The Compulsive Overeater
■The Impulsive-Compulsive Overeater
■The Anxious Overeater
■The Sad Overeater (to medicate feelings of sadness, depression, low energy, low self esteem, tend to gain weight in winter, pain symptoms, high limbic activity, low vitamin D level), Help: boost vitamin D, exercise, fish oil, SAMe supplement.
Vitamin D is only mentioned in the last one. The 2nd and 3rd ones suggest drinking green tea. It also says under supplements:
Low levels of Vitamin D associated with MS, diabetes, cancer, obesity, Alzheimers, depression. Typically, get boost from sun, but our levels are falling. Recommends asking doctor for a 25 Hydroxy-vitamin D test.
