A “bubble gut” is often seen in high-level bodybuilders on stage, despite them having extremely low body fat levels. The reason for this is still unclear, but enlarged abdominal muscles, enlarged internal organs, and/or visceral fat between the organs may contribute.
It also remained unclear what is causing these bubble guts. It has been speculated that very high protein intakes and/or anabolic-androgenic steroids (AAS) play a role.
Carrots get their orange color from beta-carotene. When consumed, beta-carotene is absorbed and accumulates in the skin and subcutaneous fat, giving the skin a subtle yellow-gold tone. Researchers call this effect “increased skin yellowness”, informally better known as a “carrot tan”.
A carrot tan is consistently rated as attractive, possibly because it signals current health and micronutrient status.
Some training philosophies, such as High-Intensity Training (HIT), propose that one set taken to failure is enough to maximize muscle growth. Others have suggested that more sets always produce more gains.
