It's rare that advanced scientific pathways involved in human metabolism make the headlines worldwide. But when it involves weight loss and Adele—two things that interest many people—it's worth exploring the science.
The science of sirtuin proteins actually goes back to the 1980s. But it wasn't until Adele performed at the Billboard Music Awards last month with a noticeably slimmed-down figure that the media started to focus on this obscure family of metabolic regulators. According to the reports, Adele's weight loss was a result of the Sirtfood Diet, which claims to activate the "skinny gene," or SIRT1, which plays a role in metabolism and appetite control. To do so, Adele both limited her calories and ate a diet focused on key foods said to boost the sirtuin metabolic regulators.
For example, resveratrol, found in red wines like pinot noir, is one activator of the sirtuin pathways. You've probably heard of its proposed health benefits before, including in cardiovascular health and general aging.
What are the other sirtuin-activating foods, or "sirtfoods"? Here are some examples:
