The human body can never lose existing fat cells, only shrink them
the verdict
REFUTED
the evidence says no
confidence 13/100
The claim that the human body can never lose existing fat cells and only shrink them is refuted by scientific consensus, which demonstrates that adipose tissue can undergo both hypertrophy (shrinking or enlarging) and hyperplasia (the creation or loss of adipocytes).
