Starting off an article about weight-loss this way is hardly motivating, but it helps to cut to the chase: It's extremely difficult to lose 30 pounds in two months. Expert doctors and dietitians agree that losing 1 to 2 pounds per week is healthy. Even if you lose 3 pounds per week for 9 weeks, you're still short of hitting your weight-loss goal. While it's certainly possible to lose 30 pounds in two months, whether or not it's healthy is another question.  Healthy weight loss comes from trimming pounds off of fat reserves without triggering the starvation response. When you cut down your caloric intake so low that your body thinks you're starving, it actually begins shedding muscle instead of fat. This is not a healthy trend. It's hard to drop pounds simply by eating less, too which is unhealthy depending on what kind of food it is. Fat is needed, but it isn't healthy to overdose the amount. Protein is needed significantly for your health. They are used to make muscles,tendons, skin, and organ. When you cut your calories significantly, your body actually has a harder time shedding pounds. This phenomenon is called diet induced adaptive thermogenesis. Perhaps it's a mechanism for survival, or perhaps it's a way for our bodies to maintain a comfortable body weight. Whatever it is — and as crazy as it sounds — you need to take in calories in order to lose weight. There are 3,500 calories in a pound. This means that you need to burn 3,500 more calories than you take in during the day in order to lose a pound of weight. That's a lot of calories to burn.  For reference, you can expect to burn between 100 and 125 calories running a mile at a semi-comfortable speed. At that pace, it would take about 28 miles (45 km), or more than a marathon, in order to shed a single pound of weight. People who run marathons routinely lose 7 pounds during a typical race, but much of that loss (~6 lbs.) is water weight. Luckily, humans can shed weight several different ways. There's muscle loss, fat loss, and water loss. Much of the...
