alt Hacker News> The part being questioned is why it's more difficult for others. For example, my wife and I share an almost identical diet and activity level, yet i struggle to keep weight on and she struggles to keep weight off and with similar lifestyles. CICO works of course, but not only do our bodies innately do different things with the calories that they process but we simply experience that world differently.
If you and your wife eat the same diet in the same quantities, it's no surprise she would have a propensity to gain weight and you wouldn't unless she's substanially larger (i.e., taller and/or heavier) than you. Women in general just burn fewer calories for similar sized vs. men. That said, this is ALL population averages. Everyone knows someone who seems to be able to eat literally anything and never gain weight... it likely is just as simple as their metabolism is such that they burn more calories than the average person. Population variation will always lead to some people with outliers both in high expenditure and low expenditure.

That's the point though. I'm saying that we burn calories at different rates. We burn fat at different rates. We have different rates of addiction, cravings, etc.
Just saying CICO is the same boring and borderline inaccurate language that has led to nearly zero change in the population at large. may as well just tell them to use physics correctly to lose the weight, because it's the same effective language.
To even determine CICO is fraught with difficulty and inaccuracy in both CI and CO. You can hand make everything, weigh every ingredient, and even then you struggle to determine how much you're CO. At best you'll have an estimated CO but then what do you do when your weight isn't changing? you have to start adjusting the math because clearly you're not burning as much as you think you are.
This is made much, much worse with the fact that we don't actually burn that many calories with exercise. And even with what is burned, the rate of burn changes drastically based on your current weight and how long you've been losing weight.
The fact is, the point is, CICO ignores all the real challenges and thereby all the real problems people need to understand and face.
