The way to a man’s heart may be through his stomach. But what do his favorite foods say about his bedroom behavior?

In the new book “What’s Your Food Sign?” (Stewart, Tabori and Chang, $18.95), neurologist and psychiatrist Dr. Allan R. Hirsch explains how grub can give away clues to a potential partner’s personality.

Sure, variety is the spice of life. But spices, Hirsch found after testing 800 people, are essential to understanding your lover’s disposition. Hirsch used already-existing personality tests with more than a thousand questions on different aspects of life, then researchers analyzed the food preferences of the test subjects.

They found curry, chili powder and cayenne consumers are peppered with logic and thriftiness. Garlic, sage and saffron lovers lack self-confidence. Dill, sesame and thyme fiends are worrywarts. And parsley, paprika and basil buffs are easygoing.

After bingeing on the book, asap procured the meaning behind a hungry man’s three squares. Eat up.

Breakfast

If grapefruit gets him going in the morning, then he likes to get it on. Hirsch says grapefruit lovers tend to be sexually expressive and perhaps even sexually aggressive. Meanwhile, doughnut eaters do not have sex-glazed minds. They’re more repressed. In general, fruit lovers are more optimistic – although Hirsch’s research finds men who crave strawberries are often insecure.

Lunch

Would he like fries with that? If so, he’s probably a contemplative person who’s not impulsive. Pizza is for perfectionists. Taco eaters take risks. And pasta lovers are pessimists, Hirsch found. Much can be said about how a guy likes his wings, too. For a loyal fellow, choose a man who orders them slathered in spicy buffalo sauce. If you have more of an appetite for a leader, pick the chap who’s sweet for honey barbecue.

Dinner

Skip dinner and go straight to dessert, where you can learn the most about a man through his favorite ice cream flavor. Chocoholics are self-absorbed. Vanilla nuts are needy. Butter pecan patrons are principled. And rocky road revelers are comfortable with success. Cone or cup? Hirsch found most men and women preferred eating ice cream in a cone – except chocolate chip consumers, who are most likely to succeed.
