No one reads Weight-Off magazine unless he is fat. Everyone

Ist statement can be re-written as:
No one reads weight-off if he is thin.
2nd statement can be re-written as:

Implies that Thin people and people eating choc do not read weight-off.
Implying that thin people eat choc and fat do not. Which is choice E
