Eating a well-balanced, nutritious diet is considered to be good for both physical and mental health. Dietary guidelines which have been in place since the 1980's advocate a high carbohydrate and low fat diet. However, recent research demonstrates that low carbohydrate and high fat (LCHF) diets outperform the standard low fat diet on multiple health indicators. Anecdotal evidence suggests that a LCHF diet is also beneficial for mental health...but is there any empirical evidence...and how does a low carbohydrate diet improve mental health? Is it weight loss (and subsequent improved self-esteem and mood), balanced blood sugars or reduced insulin? This seminar will explore the current science for balanced eating and how that relates to mental health.
