You know the old saying “never argue with an idiot, they drag you down to their level and beat you with experience”?
Never has it been more true than in the debates I keep seeing about “calories in, calories out”.
Now… this is a heads up both for the intelligent people I follow and the misguided idiots I keep seeing them getting drawn into arguments with.
The question is “does calorific intake determine body weight?”.
The answer is “yes, it does”.
What I keep seeing is arguments along the lines of “well if you believe in calories in / calories out you must believe it is due to the law of thermodynamics, so I’m going to argue with you about that”. Or “well if you believe in calories in / calories out, that all came from research of Ancel Keys so I’m going to dig up his work from half a century ago and find faults and discrepancies with that”, and so on.
All of that is beside the point.
If you’re interested in offering people a solution to their problems rather than just point scoring in arguments, the question is “if an overweight person develops the habit of eating an a total amount more suitable to maintaining their goal weight, will they make progress towards that goal weight?”. And the answer is YES.
The question isn’t “why does it work like that and if you can’t explain it to my satisfaction then it must not actually be the case”.
You don’t need to dig up studies and debate who said what and what they meant by it and how they came to this conclusion. The proof is in the answer to the following question; “have people successfully lost and maintained a healthier goal weight by simply consuming a more appropriate total amount of calories? Has it been done?”
And the answer is “yes. Many, many times in a variety of circumstances”.
What is there to argue about here? Nothing.
