Bitten has decades of experience treating patients with food addiction and has developed a holistic treatment program for food addicts in which she offers education for professionals, both in Sweden and online.

She has also developed a self-diagnosis test, which helps clients learn if they’re suffering from harmful use or addiction. It is important to know the difference since the treatment for each condition differs.

She is convinced that a keto food plan is the best option for those who suffer from food addiction — and more specifically, for those who are addicted to sugar.
