Fat tissue retains a ‘memory’ of obesity through cellular transcriptional and epigenetic changes that persist after weight loss, which might increase the chance of regaining weight, according to a study in Nature. go.nature.com/48ZTVfg
This is figure 1, which shows human adipose tissue retains cellular transcriptional changes after BaS-induced weight loss.
