Is there really a menu that reduces appetite? Reduces the craving for sugar? And improves our metabolism and calorie burning? I will answer with the necessary caution – To a certain extent, low–carbohydrate, high–protein menus can do that. Low–carbohydrate, high–protein menus are not a new trend, but rather a nutritional approach that returns in waves over decades – Each time under a different name, with a similar promise: Rapid weight loss, a sense of appetite control, and sometimes also an improvement in health indicators. Decades ago, the "Rabin Diet," which was based mainly on eggs, was well known in Israel. Later came the Atkins diet, followed by diets like Paleo, and the more stringent version – The ketogenic diet, which gained worldwide popularity thanks also to celebrities like Kim Kardashian.
Beyond names and trends: It is important to understand what lies behind this approach, and why it keeps returning time and again, especially during periods such as before Passover, when many are looking for a quick weight loss solution.
Protein diets – How does it really work? The central principle is relatively simple. What needs to be eaten: One increases the amount of protein in the menu, and simultaneously reduces carbohydrates significantly. The practical meaning is more foods like meat, fish, eggs, cheeses, and dairy products, and also vegetables are free... And simultaneously a reduction of bread, pastries, pasta, rice, potatoes, sugars, and sometimes also fruit.
This approach has received research reinforcement in recent years. Studies published in leading journals, including the "New England Journal of Medicine," found that low–carbohydrate, high–protein diets can lead to more effective weight loss compared to low–fat diets, and sometimes even to an improvement in indicators such as blood sugar levels and lipid profile.
In addition to this, there is evidence that among healthy people, this type of nutrition may contribute to reducing the risk of developing type 2 diabetes and improve risk factors associated with heart disease.
How does it work? The explanation lies in several mechanisms that operate together:
1. Firstly, the very reduction of carbohydrates often causes an automatic decrease in calorie consumption. Many of the calorie–dense foods in the daily menu – Breads, cakes, snacks – Are carbohydrate–based, and when they leave the menu, even without conscious intention, the total calories drop.
2. Secondly, protein has a significant effect on the feeling of satiety. It digests more slowly, and affects hormones related to hunger and satiety, so that many report a natural decrease in appetite and less need for snacking between meals.
3. In addition, the digestion process of proteins requires the body to invest higher energy compared to carbohydrates and fats – A phenomenon known as "the thermic effect of food." The meaning is a slightly higher calorie burn as part of the digestion process itself.
The combination of these three factors – Fewer calories, more satiety, and increased burning, actually explains why one can sometimes see relatively rapid weight loss, even without strict counting of calories.
For whom is it not suitable? Alongside the advantages – It is important to address the other side of the coin as well. High–protein, low–carbohydrate diets are not suitable for everyone, and certainly not when they are executed in an extreme and unbalanced way.
Complete avoidance of entire food groups can lead to nutritional deficiencies, especially in fibers, vitamins, and minerals found in fruits, grains, and legumes. In addition, there are medical conditions where extra caution is required, for example among people with kidney problems, or those at high metabolic risk. Also behaviorally, quite a few people find it difficult to persist over time with a menu that highly restricts basic foods like bread, pasta, or fruit.
Therefore, the correct approach is not necessarily "yes or no" to a protein diet, but rather personalization. For some people, a moderate reduction of carbohydrates and increasing protein consumption can be an effective tool for appetite control and weight loss. For others – Precisely a broader balance between food groups will be more correct, healthy, and logical over time.
Ultimately, as in most fields of nutrition, here too there is no single solution that fits everyone. Anyone considering adopting such a menu, especially for a prolonged period, should do so with professional guidance and personalization – While taking into account blood tests, health status, and lifestyle habits.
