6. ORDER THE LATTÉ
"If my clients drink caffeine, I advise them to do so strategically—about 20 minutes before a workout or midway through a long day," says Koff. At least three studies have shown the stimulant can boost endurance and fat burn during workouts. "But relying on it consistently as a bandage for fatigue won't work," she says. A caffeine jolt (like the kind you get from a Red Bull) gives you a temporary surge but can leave you feeling exhausted later. Plus, large doses can lead to anxiety and insomnia.
If you need a pick-me-up, order a nonfat latté or cappuccino. "The milk provides protein, which can help fend off a caffeine crash," says Pasternak. Country crooner Taylor Swift's coffee drink of choice, for example, is an iced caramel latté. As an alternative, try green tea, which has about half the caffeine content of coffee as well as L-theanine, an amino acid that has a stress-relieving effect on the brain. Lady Gaga and Alanis Morissette keep bottles of green tea backstage, while Koff's star clients drink matcha, a concentrated form of green tea. One brand to try: DoMatcha ($10 for 12 bags; domatcha).
