‘Home Improvement’ star Richard Karn shares the 'off-switch' that helped him lose weight

"Home Improvement" star Richard Karn shares how he lost pounds and maintains a healthy weight through mindful eating, portion control, and avoiding late-night snacks.

"I love pizza, but I can fill up on two, maybe three slices, you know, medium slices. And I'm good with that. I don't have to eat the whole pie. So I do, I have an off-switch."

"Once you do it long enough, you realize what you need and what you don't need and what triggers you to be munching on something when you don't need to be munching on something," he said.

He told Fox News Digital he’s learned not to eat after six or seven at night very often, to not wait too long to eat because then he’ll get "very hungry" and eat too much, "and, you know, being married for 40 years is a long time to have that question, you know, ‘What do you want for dinner tonight?’ because that comes up every night. And then we have to work it out."
