This approach isn't working, has demonstrably failed. Do you actually care about fixing any problems or just happy to shame people you see as less than you?
Diesel fuel technically has several times as much calories as Cola-Cola. But try drinking diesel fuel for lunch and see what comes about.

Can you come up with edge cases where my one-liner (Calories In - Calories Out) is not 100% accurate? Yes. Is that the case for the absolutely overwhelming majority of people? No. Over 70% of people in the US are overweight or obese. That's more than 2 in 3. Are we all suffering from some exotic, unknown, mysterious disturbance of the gut microbiome? Or is it more likely that we just move too little while eating too much? I think I know the answer.
Really?
It’s Calories In - Calories Out.
