Does the inverted triangle diet, like eating meat to lose weight, really have magical effects? Nutritionist Su Yanchen: May damage cardiovascular system

There are many different nutritional arguments for weight loss, but not all of them are correct! A psychotherapist once said, "If you want to lose weight, just turn the food pyramid upside down," and believed that "eating oil and meat will not make you unhealthy." However, nutritionist Su Yanchen disagrees, saying that there are errors in the content. Although it is suitable for quick weight loss, it is not recommended for long-term consumption as it may damage cardiovascular health.

Nutritionist Su Yanchen pointed out that a psychotherapist once said, "If you want to lose weight, just turn the food pyramid upside down." In fact, the argument of the "inverted pyramid diet" was first proposed in 1972 by an American cardiologist Robert Atkins. A Jin said that the main thing is to reduce the "sugars (starches, such as rice, biscuits, noodles, toast, etc.)" among the three major nutrients in the diet in a short period of time, and combine it with total dietary calorie restriction (1200~1500 kcal/day) to achieve effective weight loss.

Inverted triangle diet, long-term risks

The "Inverted Triangle Diet" emphasizes the proportions of three major nutrients: 10%-30% carbohydrates, 30%-40% protein, and 30%-40% fat. Among them, protein is 1.8-2.5 grams per kilogram of body weight, which is obviously too high. It is like "eating meat to lose weight" and is only suitable for quick weight loss. Long-term consumption is not recommended due to high cardiovascular risks.

It is not recommended for growing children to adopt this rapid weight loss method because there is no data to prove that the "inverted triangle diet" can help obese children lose weight healthily. Therefore, it is recommended to exercise regularly and reduce snacks and sugary drinks.

Weight loss diets are not suitable for everyone

Nutritionist Su Yanchen further pointed out: "If patients already have clinical symptoms, such as kidney disease, cancer and other diseases, they should follow regular nutritional advice to improve their weight problems." People who already have diseases must seek dietary guidance from professional nutritionists. "Take cancer as an example. You must not apply the dietary concept of cancer prevention to chemotherapy and radiotherapy. This will be dangerous!"

Taking chronic kidney disease as an example, the KDOQI guideline proposed by the National Kidney Foundation of the United States uses a kidney score (glomerular filtration rate; GFR) of 60 points as the benchmark. Above 60 points, the protein intake is 0.8~1.0 grams per kilogram; below 60 points, it is 0.6~0.8 grams per kilogram, and the intake of sodium and phosphorus is restricted to slow the deterioration of kidney disease.

If the patient is malnourished, protein can be increased to 0.75 grams per kilogram; when urine decreases and edema occurs, potassium ion intake also needs to be restricted. The dietary guidelines are detailed and have different dietary instructions for different periods.

People who already have medical conditions must receive dietary guidance from professional nutritionists; for patients who are malnourished, protein intake can be increased to 0.75 grams per kilogram.

Taking cancer diet as an example, to prevent cancer, you need to maintain a healthy diet; but during cancer treatment, you need to understand treatment methods such as chemotherapy and radiotherapy, and then combine them with a suitable diet to avoid malnutrition during chemotherapy and radiotherapy, which may cause interruptions in treatment and lead to worsening of the disease.

"Experts' arguments without any medical experiments or evidence will harm the medical profession!" Nutritionist Su Yanchen reiterated that one should speak with evidence, especially when it comes to therapeutic diet. One should be more cautious and return to professionalism to avoid hurting the body instead of curing the disease.
