In a large pot set on medium heat, place your oil along with two kernels of the popcorn. Caution: Be sure to wear protective covering as when the popcorn kernels pop, it will most likely pop out of the pot.
When the two popcorn kernels pop, add your remaining kernels, sugar alternative and salt to the pot.
Cover the pot with a lid and give it a quick shake from side to side.
While the popcorn is heating up, make sure that you have a large bowl nearby as you will quickly need to pour the popcorn into it. also, you will need to use pot holders or mitts as you shake the popcorn and move the pot.
Shake your popcorn pot from side to side every minute and a half to two minutes. Once it starts to pop consistently and sounds like the pot is half full, you can remove the pot from the heat or turn the heat off.
Continue to shake the pot back and forth to avoid burning the popcorn.
When the popcorn reaches the top of the pot, use a pot holder to remove the lid- do not stand over the pot as the popcorn will still be popping most likely. As a result of removing the lid, the popping kernel can jump out of the pot.
Dump the popcorn into the large bowl. Remember, the pot will be hot so take precautions.
