There is a scene in the movie "Slimming Men and Women". In order to lose weight, the heroine starring Sammi Cheng carries a kitchen scale with her when eating in a restaurant. Every bite of food must be weighed, the calories calculated, washed with water, and oil absorbed with a napkin before she dares to eat. I have to say, this is a very inspirational and healing classic movie, which tells the story of a dead fat man and a fat woman who lose weight for love and become a goddess. But some exaggerated weight loss methods are not worth learning, such as caring so much about calories, not to mention useful and useless. It is probably difficult to carry out every meal just like this in real life.

Calories are not the only measure of food weight loss.

Although cheese makers who are eager to lose weight are not so exaggerated, they have quietly downloaded mint software on their mobile phones to check the calories of food at any time. If they know, they dare to eat with peace of mind, otherwise the calorie gap will be difficult to guarantee. But there are still fish that get through the net, such as seasonings, salad dressing and some hidden fats in food, such as thousand-layer cakes, fish balls and crab sticks. God knows how much oil or fat the manufacturer put in.

In fact, we don't have to care so much, because calories are not the only criterion to measure whether food can lose weight, but also consider some factors comprehensively:

1, the amount you usually eat at one time.

Generally, the food calorie lookup table tells us the calories per 100g of food, regardless of the amount we usually eat at one time. For example, a bottle of beer has a calorie of about 240 kilocalories, which can be drunk like drinking water; The calorie per 100g sesame is 53 1 kcal, but few people have nothing to do with chewing 100g sesame, usually just a few grams on cold dishes or pies; The calorie of laver per 100g is 207 kcal, but only a few grams are eaten at a time.

2. The satiety brought by the same heat

Even with the same calorie intake, satiety may be quite different. Let's take beer as an example. A bottle of beer has a calorie of about 240 kilocalories, which makes it difficult to maintain satiety. Two medium-sized Fuji apples add up to about 240 kilocalories, but after eating them once, they are basically full without eating them. A small Portuguese egg tart has more than 240 kilocalories. Calories are real calories, but they only serve as desserts and do not occupy the stomach at all.

3. Blood sugar index and blood sugar load

This factor is one of the key factors to lose weight, because the blood sugar level directly affects the secretion of insulin, which is a hormone that promotes fat synthesis and inhibits fat decomposition. Once the blood sugar level is too high, the insulin level will rise too high, and the body will change from energy consumption mode to energy storage mode. Therefore, for the same calorie, priority should be given to foods that raise blood sugar slowly, such as 100g coarse grains and 100g white rice or refined flour, but the former has slow digestion, slow release of blood sugar into the body and low peak value, while the latter produces sugar quickly, which is not conducive to controlling fat loss.

4. Nutrient concentration

Under the condition of the same heat, the amount of vitamin minerals contained in it may be very different. For example, some snacks such as sweet bread, biscuits, cakes, chocolates, sweets, etc. are mostly provided with fat or sugar, and various vitamins and minerals are lost during processing; And some natural foods can retain rich vitamins and minerals as long as they are not overcooked. Thirdly, in the above example, the coarse grains of 100g contain minerals such as B vitamins, potassium, calcium, iron, etc., which are several times that of flour and rice of 100g, and the satiety is stronger. Many vitamins and minerals are not only necessary for health, but also coenzyme to help fat burn, so choose foods with high nutritional density.

5. Antinutrients in food

Facts have proved that many anti-nutritional substances in food are not only bad for losing weight, but also harmful to our health, especially some foods we call "junk food", such as instant noodles, sausages, fried foods, high-fat and high-calorie foreign fast food, barbecue and heavy-taste foods. No matter nitrite, trans fatty acid, saturated fat, benzoratio, heterocyclic amine or excessive salt, it will increase the risk of chronic diseases and also increase the risk of chronic diseases. The calories of a bowl of instant noodles are about 470 calories, and the calories of a cup of milk, an egg, an apple and two pieces of whole wheat bread are also about 470 calories. However, the latter can be called a healthy breakfast with comprehensive nutrition, while the former can only be used as emergency food to provide calories. Protein, vitamins, minerals and dietary fiber are seriously insufficient, and "anti-nutrients" are also extremely rich, which increases the body's unnecessary metabolic burden.

To lose weight is simply to "keep your mouth shut, keep your legs open" and "eat less and exercise more", but it is actually a complicated process involving nutritional balance, digestion and absorption, hormone secretion and metabolic regulation, and it can't be successful just by controlling calories.

Instead of obsessing about calorie calculation, it is better to change your eating attitude, reduce the intake of processed food, enjoy the authentic taste brought by natural food more, revitalize taste buds, carefully match every meal, concentrate on enjoying every bite of food, and take chewing slowly and eating only seven points full as a habitual elegance, because your feelings about your body are the most accurate "calorie calculator"!
