Eating less food does not suffer the same considerations or consequences as cutting off a limb or dropping a nuclear weapon on a country undergoing a genocide.

These are further immaterial false equivalences.

If you temporarily eat less food but regularly eat too much food, you will gain weight. Similarly, if you temporarily eat too much food, but regularly eat less food, you will lose weight. This can be connected back to our earlier agreement that it is excess food you put in your body and do not burn that causes weight gain.

If you regularly eat enough, but not too much or too little, food for your body long-term, you will maintain a healthy weight long-term.

Now we have a simple solution to obesity and, at your prompting, a simple solution to long-term weight maintenance.
