Most people have areas of their body they wish they could change. There are hundreds of workouts that promise to tone your tummy, trim your waist or tighten your butt. It’s certainly possible to build muscle in these areas, but an article from CNN points out that you may not be able to change the underlying shape of your body, even with significant weight loss.

“People come in with unrealistic expectations from magazines and spot-reducing,” says Gary Foster, director of Temple University’s Center for Obesity Research and Education. “That doesn’t happen. When you start to lose fat, it’s proportionate throughout your body, whether it’s your neck, waist, ankle circumference. You’ll come out smaller but have the same body shape.”

In other words, a person who is pear-shaped will remain a pear, and a person who is apple-shape will remain an apple. “Basically, when we lose weight, we lose weight all over in exactly the proportion that’s distributed throughout our body,” says Susan Fried, director of the Boston Obesity and Nutrition Research Center at the Boston University School of Medicine. CT scans, dexa scans and MRIs reveal that as a person loses weight, fat is reduced evenly around the body.

You’ve probably heard the claim that exercising on an empty stomach helps boost fat loss. But is there any truth to it? While the answer depends on who you talk to (and what book you read — so many weight-loss books promote the practice), most research studies and exercise science experts agree that fasting before working out is counterproductive.

Working out on an empty stomach makes sense — in theory. Proponents say that you’ll burn more fat because your body doesn’t have carbohydrates to use as energy since you haven’t eaten. However, a February 2011 report published in Strength and Conditioning Journal found that to be untrue. Researchers found that when you don’t have proper fuel in your body, your body has less energy and therefore your exercise intensity and number of calories burned suffers. During intense workouts, your body may actually pull protein from your muscle for fuel — definitely counterproductive since muscle helps to rev metabolism.

Saturated fat was recently in the news at the Institute of Food Technologists expo when experts revealed, again, that the link between saturated fat and cardiovascular disease is inconclusive. Both the public and professionals are now confused, since diets low in fat, particularly saturated fat, have been the mainstay of scientific consensus for more than 30 years. Saturated fat, a solid fat mainly found in animal foods, includes cheese, whole milk, butter, and fatty cuts of meat. It, together with liquid poly- and mono-unsaturated fats from nuts, seeds, grains and fish, make up all naturally-occurring dietary fat.

Back in the 1970s, the American Heart Association and other authorities said to reduce all fat to 30 percent of total calories and saturated fat to 10 percent or less. The recommendation was drawn from epidemiologic studies that compared the diets among different countries, in particular, the Seven Countries Study. Those studies showed a correlation between total fat intake and rates of heart disease. That, along with the National Diet-Heart Study of the 1960s, form the basis of the message that reduction in saturated fat lowers blood cholesterol and risk of heart disease.

She’s being called “The Fat Whisperer.” Hollywood starlets are flocking to her to shed unwanted pounds. Celebrities are claiming she can get them red-carpet ready as she uses the power of persuasion to encourage fat cells to leave the body. Who is this woman and what is she doing?

Mary Ascension Saulnier is the woman behind the “Fat Whisperer” nickname. Saulnier studied at the Santa Fe Academy of Natural Healing. She is also a Pilates instructor, a raw food chef, and now Hollywood’s new diet guru.

Saulnier runs a weight loss clinic where she has a plethora of treatments for her clients. Her services may include detox masks, teas, wraps, heated suits, or ultrasound treatments. While these are high tech and non-traditional tools in the weight loss arena, it’s the “whispering” that is really gaining notoriety.

Saulnier has a technique where she orders fat to leave a client’s body. She claims to be able to get to the emotional root of a client’s over-eating issue, listen to what emotions are in the fat cells, and then tell it how to move out of the body.

File this one in the “goes against everything we’ve been told” file.

A recent study published in American Journal of Physiology-Heart and Circulatory Physiology suggests that a high-fat diet is OK and even beneficial for the heart. The study, which looked at cardiac function in patients suffering from heart failure, found that that a high-fat diet improved the heart’s ability to pump, along with boosting cardiac insulin resistance (which reduces the risk of diabetes). Sounds pretty different than what we’ve been told all along right? That eating too much fat is bad for the heart?

Not so fast. According to the study which was  funded by the National Institutes of Health, the American Heart Association, and the Case Center for Imaging Research, all fats are not created equal. In fact, a balanced diet that includes mono- and polyunsaturated fats, and which replaces simple sugars and highly processed foods with complex carbs, are most beneficial for damaged hearts. Notice what wasn’t on that list of a healthy diet? Trans fats or saturated fats.
