The range is being positioned as a sub-brand alongside The Edge and Stuffed Crust. It will be available in all Pizza Hut restaurants from this month and will also be part of the chain's takeaway menu.
Hi-Light pizzas contain 33% less fat than the equivalent standard Pizza Hut offering. Options include Chicken, Ham and Veggie. The pizzas are made using a thin-and-crispy base, low-fat toppings and half the regular amount of cheese.
The range will be priced £5.49 for an individual size pizza, £7.99 for a medium and £9.99 for a large.
Pizza Hut marketing director Martin Pugh said the launch of Hi-Light is intended to meet a growing demand for healthier versions of customers' favourite pizzas.
'Hi-Light has been created after a year of intensive research and development dedicated to creating contemporary lighter products without compromising taste and quality,' he said, adding that the range has been developed in consultation with a nutritionist.
Rival fast-food chains McDonald's and Burger King have both introduced healthier options onto their menus this year amid criticism of the fast-food industry's role in the obesity crisis.
A Pizza Hut spokesman insisted Hi-Light is being launched purely in response to consumer demand and not as a result of government pressure.
Pizza Hut has no immediate plans to support the range with marketing activity.
