Diet Detectives: Spotting Sensible Diets
by Karen Asp
One week you are stuffing your face with protein. The next week, a new diet urges you to dump the protein and load up with carbohydrates. Talk about redefining yo-yo dieting.
So do you continue with your current diet? Or will friends who have lost dozens of pounds on this new diet sway you over? All you know is that you are desperate to lose weight. If that new diet works, then it is worth a try.
Before you dig into another diet, step back and evaluate it. Just as you would not buy a car without knowing anything about it, you should not jump into a diet without scrutinizing its claims. And before you continue your string of yo-yo dieting, you should learn what successful weight loss is all about.
The Keys to Successful Weight Loss TOP
Weight loss does not happen overnight. Nor should it happen to the tune of ten pounds a week. Instead, successful weight loss means losing 1-2 pounds per week, says Debra Wein, MS, RD, sports nutritionist and co-founder of the Sensible Nutrition Connection in Hingham, Massachusetts. "When you lose more than 1-2 pounds per week, you lose more than just fat mass," Wein says. Instead, you start losing part of your lean body mass, including muscle—the mainstay of your metabolism. Muscle, after all, uses more calories than fat and is a major contributor to helping increase metabolism.
It is helpful to think of weight loss as a way to also achieve good health. Losing 5%-10% of your starting weight may lead to improved health if you are overweight. If you choose to lose weight, no matter how much, it is a good idea to work with your doctor and/or a registered nutritionist.
There are 3,500 calories in a pound, so to lose one pound a week you need a 500 calorie deficit per day, which is ideally achieved both by cutting back on calories and through exercise. Regular exercise is an important component of weight loss success. "You need to get a balance between caloric intake and caloric expenditure," Wein says.
For weight loss to be successful, you have to incorporate exercise into your daily routine. "You need to get a balance between caloric intake and caloric expenditure," Wein says.
You may also need to change some of your eating patterns. For example, are you always eating in front of the television without realizing how much you have eaten? Do you eat when you are depressed, sad, or angry? Ideally you should pinpoint what triggers you to eat, and if it is not hunger, develop new, more healthful, responses to these triggers.
Why Diets Fail TOP
Inevitably, diets do—and most likely will—fail. Consider, after all, how many times you have been in this situation. You go gangbusters on one diet only to fizzle out after a few weeks. Then slowly but surely, the weight you have lost creeps back onto your body. What went wrong?
One reason as to why diets often do not work is that they are temporary interventions and do not address the issues really at hand: what is causing a person to eat a certain way and why? Most diets, for instance, prescribe certain eating habits that you follow for a specific period. Yet once that period ends, you are left to battle with your old eating patterns. Although you may have lost weight, you did not learn anything about nutrition, nor were you taught how to modify your old eating habits to maintain the weight you have achieved.
Some diets may also be too restrictive or unrealistic, Wein says. "Someone may be eating so few calories that they just can't function well," she explains. Or the diet may require giving up going out to eat with friends or even eating certain food groups.
How to Spot a Healthy Diet TOP
So how can you choose a diet that will help you lose weight sensibly and keep it off? By taking the time to evaluate diets and not believing every claim you read or hear. Before you start a diet, talk with your doctor or a nutritionist about your intentions. Then ask these questions when analyzing a diet:
A Life Change, Not a Quick Fix TOP
As Wein is quick to point out, there is no quick fix and no magic pill or supplement that will make you lose weight. ""The bottom line is that to lose weight," she says, "you have to eat well and exercise."
