To drop serious lbs, you need the one-two punch of aerobic exercise plus strength training. Resistance helps build and preserve metabolism-boosting lean muscle while burning fat and is especially key when you hit a plateau. Amanda Green lost 15 pounds in two months doing hour-long cardio DVDs, but it wasn't until she started running outside and lifting weights three times a week that she was able to ditch the last 15 of her 30-pound goal.
The researchers hypothesize that participants who abstained from animal products dropped significantly more pounds since plant-based foods include loads of filling fiber and slow-to-digest complex carbs. Though more research is needed to confirm these results, the study authors write, "Vegetarian diets appeared to have significant benefits on weight reduction compared to non-vegetarian diets."
Yes, there's a law that outlines the regulation of over-the-counter diet pills and other supplements, such as vitamins and herbal remedies, says Stephanie Karpinske, MBA, M.S., R.D. But no, supplement companies don't have to comply with the regulations (they're voluntary). Companies don't have to prove that their products are safe or that they work. Prescription diet pills, however, are considered a drug and have to go through the same strict guidelines and testing as any other prescribed drug.
“Diet and exercise are a marriage that should never divorce,” said Giancoli, noting that the benefits of exercise aren’t restricted to the sheer number of calories you burn during thirty minutes on a treadmill. (Need one of those, by the way? We have some favorites.) Instead, research shows that muscle tissue burns more calories than fat tissue, proving that “muscle mass is a key factor in weight loss.”
