45 minutes: An excellent presentation by Ben bickman. He goes over different life cycles of fat, different biological fat growth scenarios. He discusses how fat cells grow and shrink in different hormonal environments.
Not only is the data fascinating, he’s an excellent presenter, being engaging and funny throughout
Near the end of the presentation he covers a N of one case study, where somebody gained weight, under different hormonal regimes. Really fascinating data
For the down voters: he isn’t telling you what to do. He spends the bulk of the lecture literally describing how fat cells invitro grow, shrink, and react to different environments, energies, and hormones.
