What is a "negative calorie food"?
Foods that become leaner are called "negative calorie foods" because these foods are low in calories, and digesting them consumes the body's own calories, so that it takes more energy to digest them than to eat them.
Is it negative heat > in and out? Is it getting thinner the more you eat?
At the top of the list of "negative calorie foods" is usually celery, along with lettuce, cucumbers, ice water, and sometimes low-calorie fruits such as blueberries, apples, citrus fruits, etc. Most of these foods are high in water, high in fiber, and low in calories.
However, there is no concept of "negative calorie food" in formal nutrition books, and no serious nutritionist believes that "negative calorie food" can be relied on to lose weight, because there is no scientific evidence to support this concept.
Why "Negative Calorie Food"
Can't lose weight
First of all, chewing, digesting, and absorbing food do require calories, but these calories are too few and too few, accounting for only a small percentage of the total calories consumed by a person every day.
This is also normal, if humans need to consume a lot of calories to digest food, it is likely to be eliminated long ago in the long history of evolution.
Because the calories used to digest food are so low, these so-called "negative calorie" foods themselves are unlikely to contain any lower calories than this (probably only ice water or cool boiled water).
What's more, even if these "negative calorie foods" are really negative calories, that is, they contain fewer calories than the calories consumed to digest them, then don't we still have to give them calories upside down?
So where does the heat needed for our body's normal physiological functions and physical and mental activities come from?
If someone really insists on these "negative calorie foods" (or very low-calorie foods), then this person will not get enough calories, nor will they get enough vitamins and minerals, which are important nutrients needed to maintain life, and will not be able to maintain the normal physiological functions of the human body, as well as the physical and mental activities required for daily work and life, which will eventually lead to serious consequences.
So, from a nutritional point of view, these "negative calorie foods" can be used as part of a healthy diet, but they are not enough to support the normal functioning of the body.
This is the reliable way to lose weight
The best way to lose weight is to get the nutrients and energy your body needs through a proper combination of diets. Here are some tips for healthy weight loss:
Follow dietary guidelines. When it comes to losing weight, choosing which foods to choose can sometimes be confusing.
At this time, the meal pagoda in the picture below can be of great help. It encourages you to eat whole grains, vegetables, and fruits. These foods are high in fiber, which can make you feel full easily.

Eat less fat. Proper fat is needed, but even a small amount of fat contains many calories. Try to eat less fried foods and fatty meats, such as hamburgers.
Eat less sweets and unhealthy snacks. Candy, cookies, and cakes usually contain a lot of sugar and fat, but not a lot of nutrients.
Avoid sugary drinks. Try not to drink too many sugary sodas, energy drinks, and sports drinks, which can add a lot of calories. Also try not to drink too much juice.
Cool white boil is a great option to add a slice of lemon or a little juice to add flavor.
Get enough sleep at night. Many young people stay up too late, and staying up late tends to increase nighttime snacks and lead to a lack of energy the next morning.
Eat less fast food. Studies have shown that the more fast food you eat each week, the higher the risk of additional weight gain. Therefore, you should try not to eat fast food more than once a week.
Solve hunger with fiber and protein. Don't get too hungry, as it may be difficult to make smart food choices.
When you're first feeling hungry, eat a snack that combines a little protein with a high-fiber food, such as graham crackers and low-fat cheese. These foods are easily filling, but they don't contain many calories.
Be mindful of how much you eat. If you're not sure how much food you have in a serving, you can learn how to read labels. With a smaller plate, you can also reduce your food intake. Try not to eat a large bag of food – it's easy to get out of control.
If you eat at a restaurant, if you don't want to waste it, you can consider taking home the unfinished food, not necessarily eating it on the spot.
Think about why you eat. Sometimes we eat to satisfy needs other than hunger, such as boredom, stress, or loneliness.
If so, try to think of other ways to meet those needs. Such as listening to music, communicating with friends, and so on.
Hyperactivity. A great way to lose weight is to be active. The goal should be to get a total of 60 minutes of moderate-to-vigorous physical activity per day.
If you haven't exercised in a while, start slowly and gradually.
Sit less. This means watching less TV, surfing the Internet less, and swiping your phone less. Aim for "one hour of physical activity per day".
Remember, weight loss is about making a healthy lifestyle change that you can stick to – not a few miracle foods.
