One week you are focusing on protein. The next week, a new diet urges you to dump the protein and load up with carbohydrates. Talk about redefining yo-yo dieting.
You may be wondering whether you should continue with your current diet. Or will friends who have lost dozens of pounds on this new diet convince you to switch? All you know is that you are desperate to lose weight. If that new diet works, then you think 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.
Weight loss does not happen overnight. Nor should it happen to the tune of 10 pounds a week. Instead, successful weight loss means losing 1-2 pounds per week. If you lose more than that, you may be harming yourself by not providing your body with all of the nutrients it needs.
It is helpful to think of weight loss as a way to also achieve good health. Losing 5%-10% of your 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 1 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 may also need to change some of your eating patterns. For example, you may eat in front of the television without realizing how much you have eaten. Or, you may eat when you are depressed, sad, or angry. Ideally, you should pinpoint what triggers you to eat. If it is not hunger, then develop new, more healthful responses to these triggers.
Inevitably, diets can—and most likely will—fail. Consider, after all, how many times you have been in this situation. You commit to one diet only to fizzle out after a few weeks. Then slowly but surely, the weight you have lost creeps back onto your body. It can be hard to know 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 enough about nutrition, nor were you taught how to modify your old eating habits to maintain the weight you achieved.
Some diets may also be too restrictive or unrealistic. Or the diet may require giving up going out to eat with friends or even eating certain food groups.
So how can you choose a diet that will help you lose weight sensibly and keep it off? You do this 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:
There is no quick fix and no magic pill or supplement that will make you lose weight. To lose weight, you will need to eat less and exercise. You also need to continue eating nutritiously.
