Marisa Peer has some very insightful materials. I stumbled across her videos on YouTube a few months ago, and I enjoyed the advice she provided. As she had shared in several talks, the concept of not feeling that we are “enough” is central to understanding unhealthy behaviors.

By tackling this root cause of weight loss issues, people can then clear the subconscious and achieve their goals and, more importantly, maintain their weight loss.
Another topic she frequently covers regards aging.
