Betsy Bidwell

Betsy Bidwell is a nutritionist whom Marge hires to put Homer on yet another diet.

History
Betsy is formerly obese herself, having weighed 400 pounds before slimming down to normal size. Her secret to weight loss is to substitute bell peppers for everything. Homer seems to embrace the plan wholeheartedly, eating bell peppers with gusto, but Betsy is stumped when Homer gains seven pounds. It later turns out that the problem was not with Betsy's diet plan, but that Homer was cheating on his diet, eating fattening foods on the sly.
