Re: [討論] 能量消耗/攝取 假說

※ 引述《dreambreaken (小滅滅)》之銘言：
: 傳統的算卡路里減肥方式可能是錯的

計算卡路里只是為了達到熱量赤字的方式之一
有在計算卡路里=/=有達到熱量赤字
(我個人是沒有在計算卡路里的, 但我一定會看食品營養標示)

: https://tinyurl.com/3t5e7xsz
: 這是各國人均每天攝取卡路里的量
: 其中美國攝取人將近3800大卡
: 日本人攝取2800大卡
: 站在能量攝取的角度
: 美國人每天比日本人多1000大卡
: 一年下來美國人應該要比日本人增加50公斤

請教您兩個問題, 不要回答中國就好
1. 移動人口: 到美國旅行的台灣人, 在美國攝入食物熱量算是哪個國家的?
2. 移動食物: 居住在台灣的台灣人, 網購日本零食並攝入食物熱量算是哪個國家的?

: 如果拿這理論來減肥
: 看來是錯誤的

計算卡路里是方法, 熱量赤字減重是理論
方法不適合=/=理論錯誤

您說"歡迎提供正確方式跟數據"
建議您用Energy metabolism關鍵字進行搜尋
https://www.nature.com/subjects/energy-metabolism
Energy metabolism is the process of generating energy (ATP) from nutrients.

https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5081410/
Analysis of energy metabolism in humans: A review of methodologies
Methodologies to assess energy intake and appetite-related parameters
1. Food recall and food diary (本版的方式)
2. Image-assisted dietary assessment (本版的方式)
3. Food frequency questionnaire
4. Observed intake in controlled environment
5. Biomarkers of nutrient intake
6. Mathematical modeling and intake-balance method
7. Appetite measurement
Methodologies to assess energy expenditure
1. Self-reporting and direct observation (本版的方式)
2. Direct calorimetry
measures the actual heat production
3. Indirect calorimetry
assesses energy expenditure by calculating the amount of energy released
when energy substrates are oxidized
4. Doubly labeled water
5. Non-calorimetric techniques (本版的方式)
5.1 Physical activity log and kinematic measurements
5.2 Heart rate and ventilation monitoring

如同您引用Albert Einstein所說的
"If you can't explain it simply, you don't understand it well enough."
要證明energy balance實驗很簡單, 要花金錢時間而已

energy intake / calories in
https://en.wikipedia.org/wiki/Food_energy
1. Direct calorimetry of combustion
實驗步驟範例 https://education.mrsec.wisc.edu/food-calorimetry/
2. The Atwater system

energy expenditure / calories out
https://www.energymetabolismlab.com/lab-services/calorimetry-room
Whole room calorimeters allow us to simulate the free-living environment
("real-life") and measure energy expenditure (the number of calories you burn) and substrate oxidation (whether calories you burn come from carbohydrates
and fat) continuously.
https://www.energymetabolismlab.com/lab-services/doubly-labeled-water-lab
allows investigators to measure the total daily energy expenditure of
their participants in a free living environment over a period of 1-2 weeks. 這實驗也蠻有趣的
https://news.yahoo.com/metabolism-set-birth-one-lab-083017324.html
The infant chamber is meant to mimic the gold standard of measuring
metabolism in adults. Those metabolic chambers are about the size of a small hotel room. Adult participants stay in the room for 24 hours, and scientists are able to calculate precisely how many calories they burn over
that time period.
A baby's metabolism is calculated by taking precise measurements of
the amount of oxygen and carbon dioxide in the chamber.

您說"如果靠熱量赤字減肥的方式是對的
為何一堆人想減肥但都瘦不下來？"

因為想減肥=/=有達到熱量赤字

您說"我看完why we eat too much後我認為他說的是對的
重點不是不要吃
而是如何讓自己身體不想吃"

為什麼要讓自己身體不想吃? 如果需要心理諮詢服務, 請打安心專線1925
https://en.wikipedia.org/wiki/Eating
Eating is the ingestion of food, typically to provide
a heterotrophic organism with energy and to allow for growth.
Animals and other heterotrophs must eat in order to survive...

您引用 https://www.thenewslens.com/article/156417
請您點閱參考資料第一項FDA NEWS RELEASE
Today, the U.S. Food and Drug Administration approved Wegovy (semaglutide)
injection (2.4 mg once weekly) for chronic weight management in adults
with obesity or overweight with at least one weight-related condition
(such as high blood pressure, type 2 diabetes, or high cholesterol),
for use in addition to a reduced calorie diet and increased physical activity.不能了解您為何會說"缺少的關鍵字:少吃、多動、熱量赤字"
