I don't think you'll agree with me, no matter what proof I provide.
What proof have you given? None.
Anyways, it's common sense. How many people get fat eating a salad?? Hmm...rocket science!
A cup of your regular iceberg lettuce has about 20 calories in it...without dressing. From the time you eat the salad to the time it gets chewed and digested in your stomach and intestines and eventually makes its exit...the digestive process has used up that energy and then some.
