WeightWatchers put out a fabulous article on the benefits of losing weight and Heart Disease.
Losing weight can do more than make you look better — it can save your life by reducing your risk of cardiovascular disease.
The weight-heart connection is simple: Weight loss is an important shield against coronary heart disease.
If there is heart disease in your family, or you're on prescriptions for blood pressure, or your doctor warns you about extra heart risks, you may feel a bit like disease is your destiny. But take heart. In its Guidelines for the Treatment of Overweight and Obesity, The National Institutes of Health report that a 5 percent to 10 percent weight loss can make a huge difference, and February — American Heart Month — is a great time to pick up the pace toward your weight goal.
But first, find out what losing weight can do for you. It can:
•Lower the scary numbers. "Obese people frequently have abnormal blood-cholesterol levels, higher blood pressure and even sometimes bigger hearts," says Gerald Fletcher, MD, a cardiologist at the Mayo Clinic in Jacksonville, FL, and a spokesperson for the American Heart Association. All of these things are risk factors for heart disease, but losing weight can help you reverse them.
•Do double duty. Overweight and obesity are independently linked to heart disease, too. "Until a few years ago, it was thought to be an indirect link (for example, excess weight causes elevated cholesterol, which causes heart disease), but now we know that even if blood pressure and cholesterol are normal, extra weight can mean extra risk for heart disease," says Karen Miller-Kovach, Weight Watchers chief scientist. So when you lose weight, you can get double and triple benefits — you'll lower your blood pressure and cholesterol, and you'll conquer a primary risk factor for heart disease.
•Work overtime. You don't have to wait for your weight goal to see a difference in your heart health. "When it comes to heart disease and weight, there's an exponential curve," says Miller-Kovach. "A little bit of extra weight increases your risk for heart disease a little bit, and vice versa." In other words, a little bit of weight loss decreases your risk a little bit.
•Add exercise to the equation. As you're losing weight, you're more likely to start exercising, which has bonuses of its own: "Exercise has been recognized as an independent positive factor to heart health," says Miller-Kovach. "We now know that exercise tends to mobilize the fat stores in the abdomen, which are the ones that put you at the greatest risk for heart disease." Plus, says Fletcher, in addition to preserving "good" cholesterol, exercise will help you control your blood pressure, among other things.
•Help at any age... "Age factors into [the weight-heart connection] prominently," says Miller-Kovach. "Being slightly obese at a younger age causes a greater increase in risk of heart disease than does being slightly obese and elderly." In other words: It's not just how much weight you have, it's how old you are. So you might reconsider the idea that there's no reason to worry about your heart until you're older.
•...and no matter who you are. Weight loss will improve the heart health of both men and women. (Women, take note: After menopause, you're just as likely as a man to suffer from heart disease.) It will also make a difference even if you're African-American, Hispanic or Native American, populations that are said to be at a higher risk for high blood pressure, obesity and diabetes.
According to a 2006 report published in Circulation, the journal of the American Heart Association, "diet and lifestyle therapies remain the foundation of clinical intervention for prevention." In other words, while drug treatments and surgical procedures can treat cardiovascular disease, the best protection you can get comes from eating right and exercising.

Low Impact Cardio
Another good e-mail from Jillian Michaels on Low Impact Cardio!
Got a bad back, bum knee, or trick hip? These kinds of injuries can prevent you from doing typical cardio exercises like biking and jogging. Sometimes even walking is painful. But an old injury isn't a free pass to skip your cardio routine! There are plenty of other lower-impact cardio exercises to choose from.
It might be time to hop in the pool — swimming is kinder to your body than land-based exercise because your natural buoyancy in water helps you avoid the jarring knocks that can cause injuries. In water, you weigh about a tenth of your normal weight, and the range of motion for the less-fit person is much wider because the water supports the weight of the limbs. So, swimming is a good choice for people who want to exercise, but who might have problems with weight-bearing, land-based activities. Swimming might suit those who have arthritis or back problems, extreme weight problems, or are pregnant. To mix things up and target different muscles, vary your strokes during your swim between breaststroke, freestyle, butterfly, and backstroke.

Understanding Insulin Resistance
I had to post this article from Jillian Michales becuase I am Insulin Resistant and actually learned a couple new things from this article!
Understanding Insulin Resistance
We heard a lot about insulin in the days of low-carb diets. And for good reason. Problems with insulin are a root cause of some of the most dangerous health conditions, as insulin affects almost every cell in the body.
Insulin plays a critical role in how your body uses food. Its most important role is to lower the concentration of glucose in your blood. When you eat, your digestive system breaks food down into glucose, and the glucose recirculates in your blood stream. In response to the rise in glucose after a meal, the pancreas releases surges of insulin, whose job is to clean the glucose from the blood. Some of the glucose is diverted into the liver, where it's converted into stored glucose, called glycogen, for later use by the muscles. Insulin then helps turn any leftover glucose into fatty acids and stores them in fat cells where they can be tapped later for fuel.
By making poor food choices, like scarfing down too many highly processed, refined carbs (like white bread and pasta!), we can do things to cause our bodies to create too much insulin. When you repeat that cycle too many times (like by repeatedly eating sugary junk on an empty stomach) your pancreas will overcompensate and produce more insulin, which your cells will eventually start to ignore. This is called insulin resistance and it is the precursor to type 2 diabetes and it is common in overweight people. Turned away at the door, the sugar is left with no where to go. If it hangs around in your blood too long, doctors call this impaired fasting glucose (if measured in the morning) or impaired glucose tolerance (if measured two hours after a meal). You could develop full-blown diabetes if both conditions go unchecked.
While high levels of blood glucose trigger insulin release, low levels suppress it, Maintaining low levels of insulin — one of the primary goals of the diet — allows your body to more easily tap in to your stored fat for fuel. Conversely, being insulin-resistant can hamper your weight-loss efforts. Try to avoid spikes in your blood sugar, by eating regularly. Pair carbs with protein, eat whole foods, avoid sugar juices and fruits, and highly-processed carbs. When your insulin-release mechanism works the right way, it helps keep your weight in check. So strive to keep it balanced!
