These videos reference some studies on brown fat: https://nutritionfacts.org/video/brown-fat-losing-weight-thr... https://nutritionfacts.org/video/boosting-brown-fat-through-...

First hit on google: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5545200/ The effects of exercise and cold exposure on mitochondrial biogenesis in skeletal muscle and white adipose tissue

Seems like you need cold and exercise, at least in mice to get the effect in fat.

No idea.

Just passing along the info. At about the halfway period of the aforementioned video she has of her talk at a conference, she goes over the biogenesis effect, but I dont recall there being a direct study link. But in other videos, she does show screen shots of the studies when she makes statistical claims which make the studies pretty easily searchable on pubmed.

Her published stuff on foundmyfitness.com does have studies though.
