Exercise induces a phenotypic switch in white adipose tissue (WAT) to thermogenic 'beige' adipocytes via multiple mechanisms including myokine secretion (irisin, IL-6, meteorin-like), natriuretic peptides, and angiogenesis, although the metabolic benefit and necessity of this process in humans remain uncertain.
Exercise likely triggers biological changes in fat tissue (browning) in animals, but this hasn't been proven to happen or help in humans. Don't rely on 'browning' as a weight loss strategy; focus on the proven benefits of exercise like improved insulin sensitivity and cardiovascular health.
LimitedQualifiesLOW confidence
More recently it has emerged that factors produced during exercise by skeletal muscle, adipose tissue and potentially the liver act to induce the ‘browning’ of WAT in an endocrine and/or paracrine manner... leading many to suggest that the long-lasting metabolic effects of exercise may be due to the ‘browning’ of white adipose tissues. However, many of these indices have only been validated in-vitro or in animal models and as such their role in ‘browning’ human WAT are currently unknown.
Why this rating
The paper is a review highlighting significant controversy, lack of human validation, and conflicting rodent data.
