And Ian K. Smith, M.D. agrees. Dr. Ian is a Harvard graduate, founder of the SHRED Lifestyle, and the author several best-selling diet books. He explains that the liver, kidney, lungs, skin, and gastrointestinal system remove toxins that accumulate in the body. But following a detox diet full of natural foods can enhance the body's ability to cleanse. He adds, however, that dieters should make no assumptions about health when choosing a detox diet. "Detoxes have gotten very trendy, and many of them are unhealthy and quite dangerous."
At first, Samantha says she hated the bitter taste and had to force herself to drink it. But soon, Samantha was sipping on green tea and lemon every morning. She then began drinking one cup each hour at work and finished off the day with one while watching TV—a total of nine cups of green tea every day. After just one month of this regimen, Samantha dropped nearly 15 pounds.
White tea is dried naturally, often in sunlight, making it the least processed and richest source of antioxidants among teas (as much as three times as many polyphenols as green tea!). A study published in the journal Nutrition and Metabolism showed that white tea can simultaneously boost lipolysis (the breakdown of fat) and block adipogenesis (the formation of fat cells) due to high levels of ingredients thought to be active on human fat cells. If there’s such a thing as diet tea, this is it. And keep your waistline toned and tight—in record time—with these essential 29 Best-Ever Proteins for Rapid Weight Loss.
While H20 is the best bet for your body during workouts, a cup of black coffee should be your go-to pre-workout beverage. During a 1-hour time trial, cyclists who took a caffeine supplement were able to ride about a mile farther than those who took a placebo, a 2008 study published in the International Journal of Sports Physiology & Performance found. What’s more, other scientific research has linked caffeine consumption with increased endurance and reaction times. The longer and harder you can work out, the more calories and fat you’re apt to burn. The problem is, most caffeine-enhanced energy drinks are loaded with added sugars (what’s the point of an exercise-boosting drink that makes you fat?). A much more waistline-friendly way to reap the benefits of caffeine: black coffee. It’s sugar-free, packed with antioxidants and free of calories.
Why it Works: Water keeps the contents inside your digestive tract moving along. Your body needs water in order to pee and sweat. Both mechanisms are essential for your body to excrete waste. Water also creates what’s known as diet-induced thermogenesis. This means your body burns calories in order to process whatever is coming in, including water. One study also found that subjects who drank water throughout the day saw a 2% to 3% increase in calorie expenditure.
"The term 'detox' has become a buzzword that is often misused by the media and consumers," says Jackie Armstrong, MPH, RDN, EP-C. Jackie is a Performance & Wellness Nutritionist at Stanford University and the founder of Well-Fueled.com. She says that detox diets are often misunderstood. "Our organs and tissues are constantly in a state of detoxification — getting rid of unwanted substances produced by the body or from our environment." She goes on to explain that research is lacking to support the effectiveness of most detox diets.
