It would seem: drink coffee and lose weight! But it is not so easy

Another interesting study was presented by British scientists (don’t laugh!).
This is how the famous scientist, popularizer of science Ancha Baranova writes about him: “It seems that caffeine contributes to the protection against type 2 diabetes and weight gain. Those who are genetically predisposed to maintain high levels of caffeine in their blood (ie, one cup per day “inserts”) are less prone to both being overweight and insulin resistant. And those for whom one glass is not enough, can get it. The study was conducted using so-called Mendelian Randomization, a very powerful statistical tool that can distinguish between causal relationships between two data sets and mere associations.”
The essence of the study is that we have a genetic predisposition to caffeine: for someone it circulates in the blood longer, for someone less. And those who were more energized by caffeine were statistically leaner, so they had a lower risk of developing cardiovascular disease and type 2 diabetes.
It would seem: drink coffee and lose weight! But all is not so simple. As Dr Dipender Gill, a clinical scientist at Imperial College London who was part of the research team, noted: “Of course, people shouldn’t start drinking more coffee or tea to try to lose weight. After all, this can have side effects: difficulty sleeping, palpitations, increased excitability. People shouldn’t change their lifestyle or behavior, especially since it’s not yet clear why some people metabolize caffeine faster and others slower. But our findings should be used to guide further research, including potential clinical trials.”
“Coffee, like any quality drink, if you don’t drink more than one or two cups a day, is good,” says endocrinologist Dr. Zukhra Pavlova. – But coffee, in addition to its undoubted advantages, also has significant drawbacks. First, it’s addictive. And not so much physical as psychological. We all live in a stressful rhythm and that is why sometimes we have to “beat ourselves”. And coffee is usually a good “stick” and “carrot” at the same time. It has not only a toning effect, but also a pleasant smell. It also gives the feeling of a legitimate rest. Getting up and pouring yourself a cup of coffee is the right thing to take a breather in the middle of your routine. At the end of the week, when we’re tired, the number of cups of coffee can skyrocket.
The second not most pleasant side of coffee is that we rarely drink it neat. We often add sugar or syrup, cream or milk. Someone drinks coffee with cookies or chocolate, sweets. And all this already significantly increases the caloric content, and therefore the danger of insulin resistance and, as a result, the development of diabetes in the future.
Third, most people usually drink coffee after meals. Or even during meals (especially breakfast). And they simply cannot imagine life without this ritual. But coffee, like caffeine, and a drink containing tannin, binds a large number of useful substances, interfering with their absorption from food. First of all, iron, calcium and magnesium. And in general, excessive coffee consumption reduces the amount of calcium in the blood. This stimulates the synthesis of parathyroid hormone (produced by the parathyroid glands), which can lead to enlargement of the parathyroid glands and a decrease in bone density. And this is the risk of developing osteoporosis and possible hormonal disorders.
So coffee, of course, is fine, but only in limited quantities. As Zukhra Pavlova noted, a huge number of various studies are currently being carried out on various topics. Which, of course, is a good thing: they work for statistics and medical analysis. But often their results can contradict each other. Therefore, it is important to critically approach new scientific data and follow the principle of reasonableness – do not rush to extremes and follow the usual diet.
