Does the apple diet really work? Unveiling the correct scientific way to lose weight.

Does the apple diet really work for quick weight loss?

I was once interviewed by a newspaper about women's beauty and weight loss.

"Doctor, you maintain such a great figure, do you also lose weight?" a young reporter asked immediately. I smiled and told her that doctors also lose weight, but they don't do it blindly; they just do two things: control their food intake and exercise regularly.

The reporter was surprised, not expecting a professional doctor to use such an "old-fashioned" method.

I explained that although the method is "old-fashioned," it's the foundation of weight loss. This principle sounds simple because it returns to the essence of weight loss—the so-called "great way is formless, great way is simple."

However, does controlling food intake and exercising regularly guarantee weight loss? Not necessarily.

For example, the term "dieting," in most people's minds, simply means advocating eating less. However, closer examination reveals that the meaning of "dieting" is actually quite rich, and not everyone knows how to diet scientifically. Controlling your food intake but eating a very limited diet can have vastly different results compared to having a customized, low-calorie weight-loss diet.

The most typical example of a diet advocating eating only one type of food is the "apple diet." This method essentially involves eating only apples for several days, excluding other foods. We all know that a varied and balanced diet is fundamental to maintaining good health. Just like a building, the human body requires various materials such as steel bars, cement, sand, and bricks to construct. If one day I built a building without steel bars, using only cement, would that work? Certainly not, because each material has its own responsibility and function. Nutrition is the same; you can't lack any of them, regardless of whether you're trying to lose weight or not. This principle cannot be forgotten.

Therefore, the apple diet sounds problematic at first glance. How can you achieve a balanced diet by only eating apples? The apple diet isn't extreme, and its harm to the body isn't significant. This is because it's a short-term diet, not a long-term one. From a dietary perspective, it's a short-term dietary change that generally won't have a serious impact on the body, so the harm from this method isn't too great.

So, can it help you lose weight? No.

The reason is simple. As mentioned earlier, the correct way to lose weight isn't a short-term sprint, but a lifestyle. The "apple diet" can only last three days. Although you might see some weight loss during those three days, what happens after that?

Then you'll inevitably face two possibilities: Since it's a short-term diet, the results certainly won't last. Think about it—how can three days of fasting offset long-term overeating? If you want lasting weight loss, then you'd have to stick to eating only apples in the long term, which would naturally lead to malnutrition.

Therefore, neither the "apple diet," nor the "banana diet," nor any similar short-term weight loss methods are recommended. The diet we advocate for weight loss is not a short-term, gimmicky meal plan using extreme nutritional combinations, but rather a low-calorie diet that is not significantly different from a regular diet.

A weight loss diet is simply a nutritionally balanced, low-calorie diet similar to a regular diet. As long as you firmly remember this principle, everyone can create a weight loss diet that suits them.
