You've probably seen ads like this, right? "Lose 5 kilos in 10 days!", "Eat whatever you want and lose weight!", "Shrink a dress size every day!" When you hear stories like this, you might think that losing weight quickly is very easy. But are these things really as simple as they say? Are they safe? Today, let's talk about this rapid weight loss (Rapid Weight Loss).
What exactly is this 'quick weight loss'?
Simply put, if you lose more than one kilo (2 pounds) per week over a period of several weeks, we call it rapid weight loss . There are many products and methods on the market that claim to help with this. They can be divided into several main categories.
- Starvation Diets: As the name suggests, these diets severely restrict food and drink. Sometimes, you only drink a small amount of liquid throughout the day. Some people claim that these diets help the body "detox," meaning they eliminate toxins .
- Diet Pills and Supplements: There are many pills and supplements on the market that claim to speed up weight loss. These products are said to block the absorption of nutrients from food, increase the rate at which the body burns calories (metabolism), or burn fat.
- Very Low-Calorie Diets (VLCDs): This is a medically approved method. However, it is only done under medical supervision . Usually, this method is used in special cases, such as before surgery, on the advice of a doctor for someone who is severely obese .
- Creams and other devices: It is a complete misconception that you can lose weight with creams, belts, etc. Remember, no cream or patch can help you lose weight without exercise or diet.
So are these methods really effective?
When we want to lose weight, we want to see results quickly. But here's the truth.
No matter what pill you take or what cream you apply, your weight will actually decrease because you drastically reduce the amount of calories your body receives, not because of any other magic.
There is no guarantee that many weight loss products on the market are safe or effective. They are considered dietary supplements , not drugs. This means that they don't have to be proven to be safe or work before they are sold. So, don't use anything like this without talking to your doctor.
The dangers and side effects of rapid weight loss
Losing weight suddenly and rapidly is a huge stress on our bodies. This can lead to serious health problems. Here are the possible risks and side effects .
| Risk/side effect | Simply put... |
|---|---|
| Serious Risks | |
| Gallstones | This condition can occur in about 12% - 25% of people who lose weight quickly. |
| Dehydration | Dehydration. This can be prevented by drinking plenty of water. |
| Malnutrition | Especially caused by not getting enough protein. |
| Electrolyte Imbalance | Loss of salt and mineral balance in the body. This can sometimes be life-threatening. |
| Other Common Side Effects | |
| Headache, irritability, fatigue, dizziness | These are common because the body does not get the necessary energy. |
| Constipation | It can be caused by a sudden change in diet. |
| Irregular menstrual cycles in women | It may occur due to effects on hormonal function. |
| Hair loss, muscle wasting | Along with fat, the body also loses essential muscle mass and the hair also loses the nutrition it needs. |
The longer you stay on a diet like this, the greater the risk. It's especially dangerous to follow a diet that has no protein at all.
So is it never good to lose weight quickly?
You can't say that. There are some special cases.
A very low-calorie diet (VLCD) under the supervision of a doctor may be appropriate for someone who is already suffering from serious illnesses such as diabetes, high cholesterol, and high blood pressure due to obesity. Here, we are talking about people with a Body Mass Index (BMI) of over 30. With such a medically supervised program, you can safely lose 15%-25% of your body weight in about 12 weeks.
But this also has its drawbacks. It's hard to maintain a strict diet like this. This means that along with the fat, your muscles will also melt away . It also slows down your metabolism. This means that when you start eating normally again, you may gain weight faster than before .
Some special occasions
- After pregnancy: Losing weight too quickly after having a baby can reduce a breastfeeding mother's milk supply . Therefore, it is best to wait until after the baby is at least 2 months old before thinking about losing weight.
- Antidepressants:Some antidepressants can cause weight gain. If this is a big problem, you may want to talk to your doctor about switching to a medication that has less of an effect on weight.
Many people try to lose weight quickly on their own, without the advice of a doctor. For a short-term goal, like wearing a dress for a wedding or looking good at the beach. If you are healthy, restricting calories for a few days may not cause much harm. But if you do, be sure to tell your doctor about it . Make sure to eat at least 70-100 grams of protein a day, take a multivitamin, and eat foods rich in potassium, such as bananas, tomatoes, and oranges.
