We’ve traversed the interwebs in search of the perfect morning routine, forgetting to prioritize the single most important thing: jump-starting your metabolism. Well+Good recently interviewed Jenna Wolfe, a journalist and fitness expert currently working with Wellness in the Schools for its Wellness Confidential series, uncovering some interesting and practical health tips in the process.

Most notably, Wolfe does the same thing every morning, mere minutes after opening her eyes, to start her day off on the right foot: “I drink 20 sips of water. It wakes me up, kickstarts the day, revs up the metabolism, and curbs that insatiable hunger I have first thing,” she told Well+Good.

Wolfe’s recommendation is substantiated by a 2003 study published in the Journal of Clinical Endocrinology and Metabolism, which found that drinking around 17 ounces of water in the morning can increase metabolic rate by 30% in both men and women. This boost occurred just 10 minutes after drinking, reaching its maximum point roughly 30 minutes later.
