Hi F2S-Awesome!
Yes you do make sense...
Since you will be using sugar free gum, candies, and/or drink mixes only occasionally, don't worry about them!
And for those that may have a very small amount of net carbs (less than 1) won't make a real difference IF you DON'T overdo it.
Trident sugar free gum has Sorbitol, Maltitol, and/or Mannitol polyols (among other sugar alcohols) depending on flavor.
They do not provide any carbs that count toward your 20 carb allowance... So consider them 0 net carbs.
This may not be true for ALL sugar free products.
That's why it's important to always read nutrition labels very carefully.
You know the truth about Splenda. So watch out for it on food labels.
And further, you SHOULD be concerned about sugar alcohols as they can cause stall-outs and digestive problems.
Like I said before, pay attention to how YOUR body RESPONDS to sugar alcohols to see how things go.
There are some folks who can't have ANY before their
weight loss slows or stops.
Others can eat them liberally without effect.
Let your body tell you what it tolerates and pay attention to it!
