How many calories do normal people need every day? How many calories do dieters need?

The number of calorie cards that normal adults need every day is generally between 2000 and 3500, which is more troublesome to calculate. If you want to calculate, you can buy a nutrition reference book. The specific algorithm is roughly as follows: Step 1, count the time you take part in various activities in a day, such as sleeping, walking, mental labor, physical labor (including work intensity) and so on. , and record the duration of each activity. Step 2, look up the table, and finally calculate the daily calorie consumption according to the average number of calories consumed in each activity and the time of each activity, as well as your own weight, age and other factors. Step 3, look up the table and make a recipe according to the unit calorie value of each food, so as to balance the daily calorie intake with the daily calorie intake to ensure that the weight does not increase or decrease; If you want to lose weight, you should reduce it on this basis. For example, if you consume 900 calories less than you consume every day (of course, this is a big reduction, just for the convenience of calculation), this means that the 900-calorie calorie gap should be made up by burning body fat. Burning 1 g fat can provide 9 calories, so 900 calories will consume 65,438+000 grams of fat. If you reduce 100g of fat in one day like this, you will reduce 1 00g in ten days, which means1kg, and100 days means10kg. In addition, there is another way to roughly calculate the required calories according to the labor intensity and weight. This method is not so accurate, but it is easier to master. I suggest you buy a textbook on nutrition, which has a detailed introduction.

Ten healthy ways to lose weight

First, reduce calorie intake.

Nutritionists believe that no matter what you control-protein, carbohydrates or fat, what you ultimately reduce is your calorie intake. If a person consumes less than 800 calories a day, he can lose 10 pounds in six weeks. If you eat 500 calories less, you can lose 10 pounds in two and a half months. But don't lose weight too fast, or it's dangerous. It should be noted that if the calories supplied to the body are too small, each person should consume at least 1200 kcal per day; You lost your muscles. Muscle is the key for human body to consume calories and promote metabolism.

Second, eat less 1 meat and lose weight for 2 months 10 kg;

Experts point out that every 1 g of fat equals 9 kilocalories. Compared with fat, carbohydrates and protein have much lower calories per gram, about 4 kilocalories. Therefore, it is not necessary to eat less to lose weight. Fresh vegetables, fruits and grains can replace high-fat foods (such as cream) you eat every day. Experts believe that if you only eat 20-40 grams of fat every day, you can lose 65,438+00 pounds in two months. However, not everyone can lose weight by eating less fat. If they eat too much carbohydrate, they will also get fat.

Third, reduce food intake:

If you want to lose weight, you don't have to give up your favorite food. It's important to control it. If you like a certain food and eat it in large quantities, you should pay attention to reducing the amount each time. Instead of eating 200 grams of meat four times a week, eat 100 grams each time, so that you can consume less calories of 1200 kcal, and you can lose weight obviously in about seven and a half months. It is suggested that dieters put a scale in the kitchen and put up warning signs to remind themselves of the weight of food intake.

Four, every day 1 meal, liquid food for 5 weeks, minus 10 pounds:

Usually, it is very convenient to make liquid food. If you only eat liquid food or drink once a day, you can lose 10 pounds in 8 months. Liquid food should be diversified to avoid lack of nutrition.

Therefore, before or after a walk, you can eat some low-fat food or fresh fruit and drink plenty of water to replenish the body water reduced by sweating.
