Obesity is the epidemic of our time, an increasing proportion of fat, thin is beautiful is the aesthetic standards of this age, a lot of people want to stay slim, so that weight loss has become the trend of the times.
For many, even most, it should be minus some weight. The reason is very simple weight loss, either by eating less or exercising, so that the body of calories consumed more than it wants to absorb calories. For example minus 1 kg per week, it is necessary to consume 3850 calories on average every day, will consume 550 calories, the equivalent of eating a McDonald's Big Mac, if you want to consume through exercise, you can choose walking 154 minutes, running 63 minutes, 46 minutes swimming, cycling 84 minutes. Remember, this is to say every day, for seven days, it is possible to subtract 1 kg.
Minus 1 kg weekly rate is too slow for many people, so there are many ways to lose weight fast. The first is hungry, calculated above, for the average person, reduced by 550 kcal movement to the limit, so only eat less, for obese patients, doctors will start prescribing diet restrictions to achieve rapid weight loss goals. Over the past half a century, there are many ways to lose weight fast advent of very low calorie diet or eat, or drink fruit juice or a variety of drinks plus detox enema. Followed by weight-loss drug in the United States, they are in a way supplements exist. These diet pills block the absorption of nutrients or claims, or claims to increase metabolism, or claim to be able to burn fat.
Rapid weight loss sounds beautiful, but have the following questions:
No long-term effects
Overall, come and go, fast less weight will quickly rise back only slowly less weight will it be possible to maintain a long-term stay. Have had weight loss experience knows, cut down easily, difficult to sustain. Weight gain does not happen overnight, weight loss is also not happen overnight, mainly because of weight gain caused by lifestyle, habits must be improved, but also give the body time to adapt to new habits, so as to obtain a long-term effect, or only short-term changes in the body weight on it, will soon restitution.
And minus all the fat
People lose weight aim is to put the body to store fat consumed. But the body fat consumption has its limits, at a certain period of time consumed to a certain extent it is no longer consumed, which is a protective function of the human body. This is why the best reason to lose weight slowly effect. Rapid weight loss is likely to reach the target weight is better, but the reality is not all fat is subtracted, where it is mostly muscle and water, especially water.
Diet pills harm than good
Because diet pills are supplements sold by its safety and effectiveness can not be guaranteed. In effect, these quick weight loss, only a very low-calorie diet and weight loss surgery is really effective. If you want to achieve slimming effect claimed, can only rely on diet and exercise, diet and exercise are speaking of credit.
In 2009 the FDA had 72 kinds of diet pills on the market were examined and found to contain mostly illegally added drugs can cause heart attacks, epilepsy, stroke and other side effects. In 2004, FDA of diet pills containing ephedra under the ban, because it will increase the risk of heart attacks and strokes. But now there are many weight-loss drug ephedra illegal to add, in addition to other harmful components have not been detected. In this case, relying on diet pills to lose weight is a very unsafe and harmful behavior.
Diet can subtract 12% to 25% by weight at 12 weeks is very low calorie, but this is only for people who stick with it, 25% to 50% of the hungry people insist on not down. Once you stop the diet, weight quickly restored.
Very low calorie diet should be under a doctor's supervision, because it has a very rapid weight loss following these serious side effects:
Gallstones
If you lose weight quickly within a few months, then 12% to 25% of people will appear gallstones. In addition rapid weight loss and rapid weight gain cycle can also lead to gallstones. The only way to prevent gallstones avoid rapid weight loss.
Dehydration
This is because a lot of people not only lose weight when you eat less, drink less. Many people have never had the habit of drinking water has been absorbed by the moisture from the food, once restricted diet, and soon dehydration. Fast weight loss, but this is not to lose weight but dehydration, the worst case be fatal. So to lose weight must pay attention to drink plenty of water.
Malnutrition
The main reason is not getting enough protein, and therefore lose weight should pay attention to add protein and vitamins.
Electrolyte imbalance
Restricted diet can lead to electrolyte imbalances, the consequences of severe cases death occurs, in addition to also cause other health problems, such as fatigue, high blood sugar, muscle cramps, dizziness, cardiac arrhythmia, paralysis, etc., these symptoms should seek medical care immediately. You can eat a variety of vitamin and mineral supplements to prevent electrolyte imbalance.
In addition, there will be headaches, irritability, fatigue, dizziness, menstrual disorders, hair loss, muscle loss and other symptoms.
By a very low calorie diet, especially protein-free diet to lose weight would be dangerous to eat the diet with time and growth, unless obesity need to lose weight fast, such as bariatric surgery to prepare, or do not rely on this way to lose weight , but you can not lose weight on their own in this way.
Haste makes waste, weight loss is a long process, not urgent.
