Theres the topic of the whole starvation myth. I personally disagree with it but also see the validation in the opposing end.
Their main claim that appeals to me is that the body would either store most of what they would eat as fat for “survival instinct” as our human bodies are made to do when in a survival environment or situation 2 being that our bodies burn less calories in performing a LOW INTENSITY exercise. The example i remember hearing about was a study where it found that the group that walked 6 hours a day vs 2 hours roughly the same body composition, that the 6 hours did burn more calories overall due to 6 hours but less calories per hour.
Their second claim that stuck out to me was that CORTISOL is constantly elevated even the slightest when walking excessively causing hormonal issues and we all know that high cortisol that isnt from lifting weights leads to unwanted stomach fat/fat storage.
I just wanted to hear opinions backed up with reasons. This was a live conference at Rice University that people could publicly attend. I dont think they recorded the video for youtube however.
