As far as I know, Bob Arnot, a media person with medical background in the United States, has been to a long-lived area in Greece. He believes that the healthy eating habits in this area deserve attention, and drinking lightly roasted coffee is one of them. He later published a book called "The Diet of Coffee Lovers", which contained a series of dietary suggestions. However, this practice is his personal opinion. Whether science needs to be studied or not, I personally will not blindly follow it.

However, coffee itself is not high in calories. Take Star Dad as an example. In its calorimeter, a cup of 473 ml black coffee has about 5 calories. A cup of 60ml espresso has 10 calories. When it comes to instant black coffee on the market, the calories are also very low, so if you drink all kinds of black coffee in moderation, you don't have to worry too much about your weight.

So, is it necessary to have weight concerns when drinking all kinds of milk coffee? In fact, there is a major difference between milk and coffee, that is, whether other things are added besides milk, such as cream and sugar.

I drink cappuccino and latte, except milk without sugar. I don't think if the baristas were trained by the Fine Coffee Association, they would add sugar to these two kinds of milk coffees (the sweetness comes from the milk delivered, not sugar). Then, take an ordinary cup of 473ml cappuccino (milk with 2% fat, no sugar) as an example, the calorie is about 120 calories, so I don't worry too much about my weight when I drink this milk coffee.

However, if sugar and cream are added to coffee, the calories will be different. One teaspoon of 4g sugar will produce 16 calories, and two teaspoons of whipped cream will produce hundreds of calories. Therefore, if you want to lose weight, you must study the calories in various coffee drinks and see the contents of fat and sugar.
