Healthy Eating & Eating Disorders - Anorexia, Bulimia, Binging

In this episode, I discuss what drives hunger and satiety, and the
role our brain, stomach, fat and hormones play in regulating hunger
and turning off the desire to eat more. I also address how protein
is assimilated better early in the day than it is later in the day,
and why those using intermittent fasting might want to shift their
feeding window to earlier in the day. Then I delve into the topic
of disorders of eating: Anorexia Nervosa, where people starve
themselves and Bulimia Nervosa where people binge and purge their
food. I discuss some common myths about Anorexia such as the role
of media images increasing the rates of anorexia and the myth of
the "perfectionist" anorexic. I also review the symptoms, and the
brain and chemical systems disrupted in this condition. I explain
how anorexics become hyperaware of the fat content of foods and
develop reflexive habits of fat-hyperawareness. Then I discuss the
most effective treatments ranging from family-based models to those
that target the habitual nature of low-fat/calorie food choices. I
also discuss new more experimental clinical trials on MDMA,
Psilocybin and Ibogaine for Anorexia, and both their promise and
risks I review the latest work on binge eating disorder and brain
stimulation, drug treatments and thyroid disruption in Bulimia and
why the treatments for Bulimia are so similar to those for ADHD.
Finally, I discuss "cheat days," body dysmorphia and the growing
list of novel forms of eating disorders start to finish. As always,
science and science-based tools are discussed. Read the full show
