I think I have just discovered a breakthrough diet plan.
Maybe even revolutionary.
It's low cost, convenient and it really works.
(I can prove its effectiveness. I am not a paid actor. This is a true story.)
First, you need a cup of something ridiculously hot.
Steaming, in fact.
Boiling couldn't even hurt.
(Something like, say, your own invention of a vanilla steamer made in your microwave.)
The next step is the most important step.
Place the cup in your hand. Do not blow on the cup's contents. Do not!
Raise the cup to your mouth
And drink a full sip.
(The bigger the gulp, the better.)
Now you have severely burned your tongue.
This should alter your taste buds and subdue your desire to eat for at least a full day.
Perhaps even longer if you are lucky.
Nothing will taste great and everything will be semi-painful to chew, thus causing you to avoid meals you would otherwise rush to devour.
Diet plan enacted!
