"You have a lot of frozen meat, warm my hands"
"You have a lot of frozen meat, and I used the hot water first!"
"You have a lot of meat to carry, borrow me around the neck!"
Are fat people really more frozen?
It starts with fat
Fat, a common nutrient in food
After entering the human body
Digestion through the stomach, absorption of the small intestine
Temporarily stored in fat cells
When the human body needs it
Decomposed into fatty acids are consumed for use
When the amount of storage > decomposition amount
Fat increases naturally
Fat vs. thin is not judged by visual effects
It's body fat percentage
Look at the fat man
It may be a lot of muscle mass and not laxity
And looking thin and small, slender limbs
Probably the fat content is not necessarily less
Perhaps, the cold winter can give you warmth
It's a thin man by his side
For example, brother Dian, warm man one
There is a general bias against fat
Consider it a "source of obesity"
But it is an important component of human tissue
"You need fat to live!"
One of its 5 major roles is to "keep warm"!
(There are 4 more important roles at the end)
Fat, one of the places of storage: subcutaneous tissue
It's like an "isolation layer."
Prevents divergence of body temperature
During the cold winter months, help you maintain normal temperatures!
But
More fat does not necessarily make it antifreeze!
If, the body is likened to a "thermos cup"
Fat present in the subcutaneous tissue
It's like an "insulating layer."
Keep the water warm
The human body also needs basal metabolism to function
Even if you don't exercise
Merely sustaining life activities
Also consumes a certain amount of calories per day[1]
Basal metabolic rate is like water in a thermos cup
If the water itself is warm water at 30 ° C
Even if body fat is high, calories are not necessarily high
People with less fat and more muscle
Basal metabolism will be relatively high
On the contrary, it is more hardy!
Muscle is made up mainly of water and protein
Very good for heat delivery to the whole body[1]
People with high body fat can withstand the invasion of cold
But thermogenesis in the body will be "inferior"
It's freezing cold, and it's shivering
Afraid of the cold, do not distinguish between tall, fat and thin!
Keep warm everyone has to do a good job!
Fat, in addition to "keeping warm", also assumes the following functions:
1. Provide heat for our life activities
2. When subjected to external shocks, protect organs to reduce damage
3. Responsible for the storage and absorption of part of the vitamin
(e.g. vitamins A, D, E, K)
4. Among them phospholipids and cholesterol
It is the main component that makes up cells
Sterols are synthetic hormones,
Essential substance for adrenocortical hormones
But, the right thing to do is king!
Too many disadvantages are:
Obesity, fatty liver, endocrine disorders,
Arthritis, hypertension, hyperlipidemia, hyperglycemia
May come to the door
We want to consume in quantities:
1. Consume 40 grams of fat per day
It can maintain the normal metabolism of the body
1 g fat
Approximately 9 calories for the body[2]
Daily intake of 1600 to 2500 kcal
Not to meet the normal activities of the body metabolism[2]
Fat intake, which accounts for about 25% of total daily calories[2]
It's about 40 grams per day
2. Use oil carefully:
The daily intake of cooking oil should not exceed 25 grams to 30 grams[2]!
Do not consume more than 2 grams of trans fatty acids per day[2]!
Like vegetable creams containing trans fatty acids
Margarine, shortening
Cocoa butter substitutes, margarine, etc
Made of puffed foods, fried foods
Eat less desserts, etc.
I hope you meet a person who knows cold and knows hot
Every cold winter, there is a place to warm in the heart
