The Cop Out star, who suffers from diabetes, has adopted a more healthy lifestyle in the past year, changing his eating and exercise habits.
Morgan reveals he's been using the NutriSystem diet plan to help battle the bulge - and he's more than pleased with the results.
He tells UsMagazine.com, "I use NutriSystem. The most weight I lost was 10 pounds in two weeks.
"(I eat) Corn Flakes, Cheerios, Raisin Bran, they have nutrition bars that are delicious. I have them in my house."
But Morgan confesses he's slipped up a few times in his efforts to eat healthily: "I have to cook my entrees. I cheat sometimes, but I try not to."
And he insists the weight loss has nothing to do with his new Hollywood career - it's simply to minimise health risks.
He adds, "I'm not obese or anything, but I wanted to come down off the weight and lower my blood pressure."
