Unrealistic Weight Loss Plans

While losing weight is theoretically simple -- burn off more calories than you consume -- the emotional battle and need for a quick fix often sets us up for failure. Dieters sometimes turn to fad diets to jump-start their weight loss program. While some can achieve moderate results, the weight loss is most often temporary. Fad dieters will usually gain back the weight they lost and sometimes even more in a very short period of time.

The Catch on Caffeine

Nine out of 10 Americans consume some type of caffeine regularly, making it the most popular behavior-altering drug. For most people, moderate doses of caffeine (about two to three cups of brewed coffee a day) are not harmful. However, heavy daily caffeine use (about four to seven cups of coffee) can cause restlessness, anxiety, irritability, muscle tremors, sleeplessness, headaches, nausea, diarrhea or other gastrointestinal problems and abnormal heart rhythms.
