Why Quick Weight Loss Diets Backfire: Five Warning Signs of a Fad Diet
Imagine that you wear a size 14 and you pin a picture of a size 8 dress to the fridge as motivation. If you are not wearing it a month later, you are likely to feel guilty, frustrated and angry, and that is exactly the mood in which people give up, or turn to a fad diet that promises fast results. A better plan starts with a realistic goal and a way of eating you can keep.
What is a realistic goal?
Smaller, achievable targets work better than a dramatic one. The National Institute of Diabetes and Digestive and Kidney Diseases says that experts recommend an initial goal of 5% to 10% of your starting weight within six months. For someone who weighs 200 pounds, that is about 10 to 20 pounds. The Centers for Disease Control and Prevention says that losing about 1 to 2 pounds a week is more likely to be kept off. If you like the new-clothes idea, go down one size at a time, and do not buy anything that costs you a second mortgage. Our post on the weight loss plan to aim for explains how to set goals.
Why do fad diets fail?
A fad diet is a plan that is popular for a while because it promises quick, easy results, and then fades. Most of them fail for the same reasons. They are too strict to follow for long, they do not teach you new habits, and the weight you lose at first is often water and muscle that comes back when you return to normal eating. Quick weight loss can also bring problems of its own, such as gallstones, tiredness and loose skin.
What are the warning signs?
1. It tells you to skip meals. Going for long periods without eating is not a healthy habit. It can make you ravenous so that you eat twice as much at the next meal, and for people with diabetes who take insulin or certain other medicines, skipping meals can cause low blood sugar, which is dangerous. Ask your doctor before you change how you eat.
2. It ignores exercise. Our bodies are designed to move, and regular activity is good for the heart, the bones and the mood. A plan that asks you to diet without any activity is missing half of what works, and a plan that relies on exercise alone, without looking at what you eat, is missing the other half. Food and movement belong together.
3. It promises fast results or sets a rigid schedule. Be wary of any plan that guarantees a certain number of pounds in a fixed time. Weight loss is a gradual process, and the pace varies from person to person.
4. It bans whole groups of food or needs special products. Plans that cut out all carbohydrates or all fats, or that require you to buy powders, pills or meal replacements, are rarely suitable for the long term. Low-carb and low-fat diets can both work, but a study that compared them found the differences between brands of diet to be small.
5. It does not mention a doctor. If you have a health condition, take medicine or are pregnant, a good plan will tell you to speak to your doctor first.
How can you tell it is working?
Pay as much attention to how you feel as to the numbers on the scale. If you are losing weight slowly, but you have more energy, sleep well and feel positive about your efforts, you are probably doing fine. The NIDDK guide to choosing a safe weight loss program advises that the best plan is one that is backed by science, tailored to your health, culture and preferences, and that you can stick with over the long term.
