Well Eric, we must agree to disagree on one thing: I don't think hunger ever equals healthy weight loss.
If it's TRUE hunger (physical pains) then people aren't eating enough.
If it's hunger cravings (physiological / psychological) then it's usually too much insulin - often the result of carbs.
I'm sure we agree here on reducing carbs as much as possible.
If it's a general feeling they 'might be hungry' because they're too tired, etc., then it's likely a result of too little FAT in the diet.
Now here's the real difficult one - if it's a person who experiences emotional/psychological cravings for food, then it's going to be about changing the mindset. Instead of food as a reward or comfort, food must be seen as fuel, and weight-loss and better health as a reward. It's not easy for some people to get there, and they may need help. Others have the willpower to easily change
(well, maybe not easily) their mindset/thinking in these regards.
Instead of being "prepared to be hungry" I'd like to think of it more as "prepared to use willpower to resist cravings" ... That's my personal opinion, anyhoo.
We also agree there is NO MAGIC PILL.

There are certainly things that can help with weight loss - but never to the extent of manufacturer claims. 99% of the weight-loss equation is proper Diet and Exercise.
