>In the sense that a body will definitely lose weight when starved?
If your maintenance calories are 2700kcal and you eat 300kcal less than that, is eating 2400kcal starving for you?
Most people cannot tell a difference if they eat 100-150kcal less in a day.
>Or in the sense that counting calories is broadly effective as a weight loss strategy?
Yes, it is, and the reason people fail with it is not because calorie counting doesn't work, but because people's maintenance calorie estimates are often poor.
Deficit = maintenance calories (TDEE) - calorie intake
In this, even if your calorie tracking is on point, a deficit requires you to have a decent estimate of maintenance calories.
To throw a monkey wrench into all this, your maintenance calories often shift downward as you progress in your "diet" journey.
calorie restriction can cause a reduction in resting metabolic rate through "metabolic adaptation". that is, your body gets used to the deficit (by shedding metabolically active tissue and other things*) and burns less calories at rest. so, paradoxically, restricting or reducing your caloric intake can have no effect whatsoever on your weight.

No, that's incorrect reading of this.
It's already factored in our algorihtm: https://macrocodex.app/knowledge/macrocodex/smart-calorie-bu...
Cool but then again what does calorie "unrestrication" cause? Tip: look at the top leading causes of death in the US

I would have thought that it would mostly be because they can't resist that extra snack.
Or 'optimistically' underestimate the calories in the not pre-packaged food.
Serious question: Is there a significant variability in how the food calories are absorbed? Maybe different combinations are not absorbed equally efficiently (like with water/oil-based vitamins)

This is a pretty good inadvertent explanation for why a lot of people come into this discussion waving around morality arguments, lack of discipline, etc.
The average person gains a couple pounds a year. Adds up. How many calories do you think that is, amortized throughout the year? I'll help you with the math. It's 19. The average person eats 19 calories per day beyond maintenance.
It's not "weak willed slob cannot resist that extra snack."
I did not mean literally starving, I meant giving the body fewer calories than it wants.
I feel like discussions like this attract a number of people who've never actually been overweight and then lost the weight and tried to keep it off longer than a year. So much bro science, so much condescension, so much smug analysis that anybody who cannot resist their own body's hunger indefinitely are just weak.
A bit more complicated than that, CICO is not the answer. It's an observation, not a strategy.
