Overall the company posted a 6% rise in sales to £422 million while like-for-like sales rose by 3.8% during the six months to July 2.
Greggs commercial director Malcolm Copland said: "Greggs is well-loved for its traditional pasties and sausage rolls, but we recognise that our customers are increasingly looking for lower calorie options too.
"We understand that eating healthier means many different things to different people, it's also about freshness as much as it is lowering intake of calories and fat."
The chain, which has 1,700 shops nationwide and serves more than six million customers a week, first launched its Balanced Choice range in 2014, offering lower calorie breakfast, lunch and snack options such as salads, soup, porridge pots and fruit.
It has also removed hydrogenated fat, monosodium glutamate and all artificial colours and flavours.
