Can drinking black coffee really help you lose weight? How many cups of coffee are appropriate for a day? Will you be hungry if you drink coffee?

When the weather is cold, many people will want to drink a hot drink to keep the body warm! But does the drink you drink really protect you from the cold? Do you often wonder why it is still chilly after drinking a hot drink? It is often said that hot cocoa and hot milk tea are astonishingly high in calories, so can drinking sugar-free tea or black coffee avoid walking on the mountain? The following is a list of common mistakes and myths in winter. Ask the dietitian to give you some advice!

If you still think that drinking black coffee in winter can burn fat and warm you up, you may want to be vigilant! Zhao Huanying, dean of Morninglight Health Nutrition specialist, once treated a 29-year-old OL who was afraid of cold physique, so she often warmed her body by drinking hot drinks. Amy, who is worried about being out of shape, never orders sugary drinks and afternoon tea desserts with her colleagues. When she feels cold, she chooses hot black coffee to keep warm. She thinks that black coffee has no calories and will not get fat, so sometimes she often skips meals when she is busy in meetings. I relied on black coffee to stop my hunger. I drank a record five cups of hot coffee a day.

Unexpectedly, the physique of being afraid of the cold has become more and more obvious in a winter. Even indoors, down coats and warm bags dare not leave the body, and they have to wear three extra sweaters when they go out. Even the quality of sleep declined, she often felt tired, and she would feel hungry and want to eat all the time. As a result, she gained 10 kilograms in three months, which bothered her very much.

Zhao Huan-ying explained that this OL, like many beauty-loving female friends, used extreme ways to control her diet in order to maintain her figure, and developed a weak, cold-afraid and difficult-to-lose physique, which also caused two major problems because of her poor nutritional concept.

1. The unbalanced intake of sugars, protein and fat, and the lack of heat-producing raw materials affect the operation of the "self-heating" function of the human body.

two。 Consuming large amounts of caffeine to speed up metabolism will not only lead to poor sleep quality at night, but also lead to an imbalance in the body's metabolism, which will also greatly increase hunger. It is easy to lose control of emotional overeating after relaxing after work. Causing the weight to rise in a straight line and out of control.

Question 1. Is a high-calorie hot drink more effective against the cold?

In winter, many people will supplement high-sugar, high-calorie hot drinks, such as hot chocolate milk, hot milk tea as the first choice for heating, thinking that the effect of keeping out the cold is fast and good. However, the theobromine contained in its hot chocolate has the effect of relaxing the esophageal sphincter, and drinking too much can easily cause gastroesophageal reflux. And gastrointestinal dysfunction or cold patients drink also easy to cause indigestion and flatulence. Most importantly, it can also lead to obesity and increase the risk of cardiovascular disease and metabolic syndrome.

Zhao Hanying, a dietitian, said that although sweets can make people feel happy, and the sugar can be quickly metabolized into ── glucose, an important source of calories for the body, assisting in the operation of the thermogenic effect. However, in a situation where it is difficult to accurately handle the amount of sugar intake, it is clear that the intake of energy is enough to produce heat, but uncontrollably drink more extra sugar and fat, which will cause the weight to rise in a straight line.

In the case of people's favorite whole-sugar hot precious milk, a cup of nearly 650 calories is equivalent to eating 32 cubes of sugar, which can only be consumed by stepping on a flywheel for two hours in a row. How to avoid drinking too many calories? Zhao Huanying suggested that the calorie of a drink should be limited to 200 calories so as not to eat too many calories and get out of shape.

Question 2. Only drink sugar-free tea and black coffee, keep warm and not afraid of fat!

In fact, it may speed up metabolism and eat more calories.

Zhao Huan Ying dietitian reminded with his own outpatient experience that in addition to the above-mentioned "ant people" who are addicted to sweet drinks, many "virtual warm people" are often seen in the clinic. What they have in common is that they care about their figure and don't want to get fat, but they also want to feel warm immediately after eating. Usually this group of people consciously avoid sugary drinks and switch to low-calorie drinks such as black coffee and hot tea to warm up. In particular, it used to be a common folk prescription for caffeine to reduce fat, which made many girls who are afraid of cold and love beauty flock to it.

However, Zhao Huan-ying, a dietitian, points out that although the caffeine in drinks such as black coffee and hot tea accelerates metabolism, the drink itself is not nutritious enough to provide the energy needed for the thermogenic process. As the body accelerates calorie consumption, blood sugar decreases, which may lead to a backlash of cold and hunger, leading to a desire to eat more high-calorie foods. At the same time, excessive caffeine intake can also affect the absorption of some nutrients, such as increasing the excretion of calcium in urine and reducing intestinal absorption of calcium, while calcium deficiency in the body is prone to cramps and may have a long-term risk of osteoporosis.

So, for the sake of health, you'd better give up drinks as soon as possible. As long as three normal meals, eat enough starch (sugars), high-quality protein and fat, the body has enough energy to run, naturally warm up, do not need extra hot drinks to warm up!
