1. FDA stated that low calorie food contains 120 kal/g or less,
2. Tharp & Young on 'Ice Cream: An Encyclopedic Guide to Ice Cream Science' book, stated that most typically, 'reduced calorie' product provide >25% fewer calories per serving than predetermined standard,
3. US regulations stated that low fat ice cream contains 3g fat or less per serving (about 120mL).
However, I couldn't find information about how many calorie (maximum) are in low-calorie ice cream (based on regulations/ products in general).
Thank you in advance for helping.
I have written a calculator that you can use to obtain accurate estimates of calories in ice cream- see https://www.dairyscience.info/energy/label.asp . There is an accompanying article that explains the underlying nutritional science and maths.

Actually to reduce the calories in ice-cream the source of sugar is changed. i.e. instead of table sugar i.e. sucrose producing 4 Kcal/g other sweet compounds i.e. stevia or artificial sweeteners like aspartame, Saccharin which produce very low calories. The other way to reduce calories is to reduce the fat (9 Kcal/g) content and replace it with fat mimics. So, the exact amount of calories depend on the process. I think others points are well clear in previous answers.
Now low calorie ice creams with low glycemic index are available in market which are stevia or artificial sweeteners like aspartame based. But original taste is altered.
