Marlene Koch’s first version of this cookbook, “Eat What you Love,” was the top-selling book in the history of QVC, so it’s perhaps no surprise that the registered dietician and cooking instructor is back with “Eat More of What You Love” (Running Press, $27).

The book basically takes comfort foods, restaurant favorites and popular desserts and slims them down, mostly by substituting ingredients. Koch’s New England clam chowder, for example, still contains bacon but cuts calories and fat by using low-fat milk and non-fat half and half as a substitute for the cream. She switches out the potatoes in favor of turnips.

A regular bacon cheeseburger comes packed with 720 calories, 34 grams of fat and 1,460 milligrams of sodium, but by switching from ground beef to chicken and using reduced fat cheese, Koch gets those numbers down to 320 calories, 10 grams of fat and 420 milligrams of sodium.

Those popular Starbucks pumpkin muffins contain a whopping 490 calories, 24 grams of fat and 10 teaspoons of sugar. Koch’s cream cheese-filled pumpkin muffins are made with applesauce, molasses, egg whites and a granulated sweetener (like Splenda), and contain just 140 calories and 4.5 grams of fat.
