You might very well eat processed chips, cereal, energy bars and pasta as the bulk of your diet and still be heavier than someone following an omnivorous diet consisting of lean meats and leafy greens. Long-term vegetarians, though, do tend to have less body fat and lower cholesterol than meat eaters, reported a study in Nutrition Research and Practice published in 2012.
Even if you do meet your goal, it's nearly impossible to keep off the weight over the long term: "The amount of restriction required [to maintain that number] will make you so hungry that you’ll eat everything in sight—it’s survival instinct," Dr. Seltzer says. And since calorie restriction gradually slows your metabolism, your body will be less prepared to burn the foods you binge on, he adds. That could mean gaining more pounds than you lost in the first place.
Notes: Chop the sweet potatoes and halve the Brussels sprouts, and place on a sheet pan. Drizzle with 2 teaspoons olive oil, season with salt and pepper, and toss to coat. Roast at 450°F (230°C) until tender, about 15 minutes. Brush the chicken with 1 teaspoon olive oil and season with salt and pepper. Grill over medium-high heat until marked and no longer pink in the center, about 5 minutes per side.
With a caffeine count higher than coffee, these teas kick your metabolism into gear. In a study published in the journal *Physiology & Behavior*, a 3-4 percent increase in metabolic rate was measured in both lean and obese subjects after a single 100 mg dose of caffeine. Look for teas made from this caffeine-containing fruit; if you want to skip comparative shopping, just grab a box of Celestial Seasonings' Fast Lane, which clocks in 20 mg above your daily cup of coffee at 110 mg caffeine.
A study published in the American Journal of Clinical Nutrition examined the anti-obesity effects of tea flavones. The study analyzed 4,280 men over a 14-year period. The researchers focused on 6 specific catechins and 3 flavones during the study period. The study was also adjusted for factors including type 2 diabetes, smoking status, and lifestyle. After the adjustment, researchers found that increased flavone intake resulted in healthier BMIs. The improvements were seen mainly in the female participants.
While it is an active weight loss supplement, there is no scientific research that proves that it causes weight loss. In fact, the National Institute of Health does not recommend the long-term consumption of Senna tea. This is because long-term and high dosages can cause liver damage, heart function disorders, dehydration, abdominal pain, intestinal blockage, and diarrhea.
Love chocolate but have no self control with it? Try slowly savoring a piece or two of dark chocolate with at least 70 percent cocoa the next time you crave it. Just a little dark chocolate helps to lower your cravings because the bitter taste signals the body to decrease your appetite. Not to mention that the steric acid in dark chocolate helps slow digestion to help you feel fuller longer. If dark chocolate is too bitter for you, try having a piece with a cup of black coffee—it'll bring out the sweetness!
