“A study by David Jenkins, MD, PhD—the University of Toronto pioneer in low-glycemic eating — demonstrates that eating small portions at frequent intervals is good for your health in a number of remarkable ways. Within the study, they found that people who ate every three hours reduced their blood cholesterol by over 15% and their blood insulin by almost 28%. That’s key, because in addition to regulating your blood sugar level, insulin plays a pivotal role in fat metabolism, inflammation and the progression to metabolic syndrome. When your body produces less insulin, you’re much less likely to convert dietary calories into body fat.
If you need a pick-me-up, brew some green tea. The low-calorie drink is packed with antioxidants called catechins, which may help you burn more calories and fat. One study suggested that drinking 4 cups of green tea every day may lead to decreases in weight and blood pressure. To make it even healthier, add a squeeze of lemon -- it helps your body absorb them.
Cheese isn’t traditionally thought of as something you consume to encourage weight management, but calcium-rich Parmesan, when eaten in moderation, can help stave off sugar cravings that can easily lead to weight gain. How does that work, you ask? The native Italian cheese contains the amino acid tyrosine (a building block of protein) which has been shown to encourage the brain to release dopamine without any unhealthy insulin spikes. What’s more? The combination of calcium and protein found in dairy products such as Parmesan has been found to increase thermogenesis—the body’s core temperature—and thus boost your metabolism.
Set (and write down) reasonable expectations for what you plan to achieve during your challenge. “You can absolutely make a difference in 10 days,” says Brooke Alpert, RD, a dietitian in New York City and the author of The Diet Detox, but don’t expect to shed 20 pounds a la The Biggest Loser. “While actual weight loss will be around three to four pounds, you can really notice the difference in the way your body feels in about a week.”
Make sure that everything you're eating is whole — as in nothing processed or packaged. Since salt is a preservative, these are the foods that are highest in sodium — something to keep in mind when planning your meals. Plan on making sure that all items you choose are fresh. That means filling up on fresh fruits and veggies, whole grains, low-fat dairy, and lean protein.
The Biggest Loser program has come under attack with recent revelations that its amazing, as-seen-on-TV results are both pharmaceutically assisted and likely to reverse. Living proof that the medical community’s understanding of weight loss is still evolving: The diet still stands in third place on US News’ & World Report’s list for Best Fast Weight Loss.
