Gastrointestinal disorders are another common cause of unexplained weight loss – in fact they are the most common non-cancerous cause of idiopathic weight loss. Possible gastrointestinal etiologies of unexplained weight loss include: celiac disease, peptic ulcer disease, inflammatory bowel disease (crohn's disease and ulcerative colitis), pancreatitis, gastritis, diarrhea and many other GI conditions.
Even if you start slow, each bit of weight you lose will give you more energy to keep going. “Just a 5 percent drop in weight can help lower blood sugar levels and blood pressure and improve sleep quality, all of which increase energy,” Sass says. Because your body isn’t working as hard, you’ll have more resources to perform more healthy activities. And in a positive cycle, that first bit of extra energy will make changes you’re making stop seeming like such a chore. “When you have more energy, you’re more likely to feel motivated to be active and make healthier choices,” Sass says. Exercise itself has also been shown to boost energy levels. Check out these other incredible ways your body changes after just one workout.
Carb crazy? Consider this: Refined carbohydrates, such as bread, potatoes and rice, create a surge in insulin that in turn drives down your resting metabolic rate, explains Aronne. "It's important to keep carbohydrates in your diet, but really focus on fruits, vegetables and whole grains, which have less of an effect on insulin levels," he explains. And when buying whole-grain breads and cereals, make sure the first ingredient listed is whole wheat, whole oat or cracked wheat.
Out of sight, out of mouth? Simply reorganizing your pantry staples could translate into serious calorie savings. A study published in the Journal of Marketing found that people are more likely to overeat small treats from transparent packages than from opaque ones. For this reason, many nutritionists suggest keeping indulgent foods in the pantry on a high shelf so that you’re less apt to mindlessly grab them.
It's a one-time investment you'll never regret. Here's why: Strength training builds lean muscle tissue, which burns more calories — at work or at rest — 24 hours a day, seven days a week. The more lean muscle you have, the faster you'll slim down. How do you start strength training? Try some push-ups or a few squats or lunges. Use your free weights to perform simple bicep curls or tricep pulls right in your home or office. Do these exercises three to four times per week, and you'll soon see a rapid improvement in your physique.
In 2008 between US$33 billion and $55 billion was spent annually in the US on weight-loss products and services, including medical procedures and pharmaceuticals, with weight-loss centers taking between 6 and 12 percent of total annual expenditure. Over $1.6 billion a year was spent on weight-loss supplements. About 70 percent of Americans' dieting attempts are of a self-help nature.
You can make alterations to this ratio depending on what foods you like, how your body responds, and your daily activity level. If you'd rather, you can change this ratio to make 30 percent of your calories from fat, 30 percent from carbs, and 40 percent from protein. Or, you can do a 20/30/50 split. The idea here is that macronutrient distribution does not follow a "one size fits all" template.
Adding resistance training to your exercise routine is a great way to boost your weight loss regimen. If you are looking to lose weight quickly, you should try some kind of weight-lifting exercise three times a week. Perhaps schedule your workouts for Mondays, Wednesdays, and Fridays so your muscles will have a day in between to rest. (That way, you have less of a chance of injuring yourself.) Or, take a cue from Livestrong.com and try circuit training, which will help you burn even more calories.
Interval training can also be a very effective weight-loss tool. It's pretty easy to incorporate into any fitness plan because it can be applied to a variety of settings, and different types of equipment can be used. Choose an activity that you can do at a high intensity (greater than 80 percent of your maximum heart rate) for 30-60 seconds, then follow it with 30-60 seconds of rest.
