If it helps, yes. What can it hurt? Why not?
Paleo and Keto have been/are my diet choice. I feel 1,000 % better with no or low carbs and no sugar. But that's me.
Everyone is different.
In America it is damned hard for carb eating people to count calories. I think they want to and I think they want to lose weight. I also believe it is very difficult for people who want or need carbs in their diet. Sugar? Screw that. No, to sugar in every form.
Processed food is non-food. Crap. Sugar laden poison. Don't get me started.
Everything in America has buckets of chemicals and sugar in it. Read the labels. If you can't pronounce it, don't eat it.
Outside of the US Americans often remark about the fact that food tastes so much better. Ha, no ****! It's because they are eating actual food. Real, unprocessed food. Fresh food, very often local food. Vegetables are fresh and local. Amazing! Portions are much smaller.
We just returned home from Las Vegas. While there my wife and I noticed how much more obese Americans are than even a couple of years ago. Try walking down the crowded sidewalk in LV behind massive waddlers who are making a grand effort to get from one place to another. It's like a freaking traffic jam. Often, everywhere, a lot.
Look, those good people don't want to be obese. I've never met anyone who wants to be a slow moving mound of fat.
Where are you going to eat when you are out of town and trying to avoid trash carbs and sugar? It can be done, and without a great deal of effort. It requires a bit of planning.
If people count calories, then yeah, put it on the menu. Why not? If it helps then why would it hurt?
We are all in this together.
