> When a person gains weight, the number of fat-storing cells in their body doesn’t change; instead, each one expands to store more fat within it by changing the way it responds to and stores nutrients.<p>Is this true? I thought the number of fat cells increase when you gain weight but don't decrease when you lose it.<p><a href="https://pubmed.ncbi.nlm.nih.gov/29991030/" rel="nofollow">https://pubmed.ncbi.nlm.nih.gov/29991030/</a><p>> A decrease in body weight only changes fat cell size (becoming smaller), whereas an increase in body weight causes elevation of both fat cell size and number in adults.
