The possible artificial sweetener issues implied by the article ("may be poison") are ultra scary.
40% of the U.S. is overweight, 11% are diabetic, etc etc. There is no such magnitude of a problem due to erythritol or artificial sweeteners.
If "too many calories" were easy to solve we would not have an epidemic of it.
Also, you forget that sweeteners still cause an insulin release and some research shows that their effect on metabolism might be even worse than sugar itself because, being zero calories, they do not contribute to the sense of “caloric satiety,” so for the same volume of food your body has released more insulin.
It’s convenient for companies to claim sweeteners are safe and sugar is the devil, but consumers should take such a claim with a grain of salt. There is no silver bullet, and dietary sciences is a field of bad science and enormous commercial incentives to lie. A good rule of thumb is whatever we have consumed for thousands of years is likely not that bad. Sugar in quantities should be avoided, but elsewhere you have claimed that it is bad for you and I have to disagree with such hyperbole, compared to something we’ve eaten for less than 50 years created by food lobbies.
Now, implementing this is hard or maybe impossible for many individuals, I'm not denying this. The solution is simple, but for some it is not easy to implement.
It’s just that some people have mental addictions or whatever problems that makes them want to overeat or not exercise enough. But the solution itself is simple and straightforward.
From Taubes' Good Calories, Bad Calories:
> “To attribute obesity to ‘overeating,’” as the Harvard nutritionist Jean Mayer suggested back in 1968, “is as meaningful as to account for alcoholism by ascribing it to ‘overdrinking.’”
Obesity etc are hormonal issues. It is not simple calorie-in, calorie-out math. I have been on a diet, off-and-on, for 15 years, and I can notice craving for carbs increase after "slipping/cheating" by consuming sugary food. While I generally manage to avoid reaching for snacks, I can only imagine how people can struggle with this, more so when others around them are stuffing themselves with food rich in sugar.
- If I consume more than 2,300 kcal per day, I gain measurable weight in weeks.
- If I consume less than 2,100 kcal per day, I lose measurable weight in weeks.
- Physical activity has little effect on my weight change.
- Age has little effect on my weight change.
- When losing weight, I must work out to retain strength. Moving around an extra 10 kg takes strength that is lost when the weight is lost.
In my case, any hormonal effects are secondary to the above. I've changed what I eat over the years and my weight didn't change if I consumed the same kcals. There are likely subtleties I am missing, but eating less works for me. YMMV
I sometimes binge on cheese and nuts or peanut butter when I'm not at my best, but even when I do this for weeks, and I'm talking an extra 2000 calories in a day which is easy with those things, I haven't gained weight (fat). I don't feel as good and I don't recommend it, but I think it's safer than eating sugar if one is going to binge. I had a couple years 10 years ago where I ate sweet things most days and did gain noticeable weight (fat). So it's not like I'm genetically not going to gain weight either.
As an aside, physical activity might not affect weight change as much but it will affect the fat/muscle ratio.
The extra 200 calories would be more of the same, just bigger portions. I record everything by weight when eating at home, and have a good feel for calories per unit weight, but double check often. Cheeses are about 100 cals per oz, breads or snacks with little fat (pretzels) are 80-100 cals per oz, nuts are dangerously calorific at 160-180 cal per oz. Peanut butter is the same. I eat nearly everything, both good and bad for me, but keep track of calories and it's been working for me. I do eat ice cream occasionally, with full awareness of how much. My calorie limit is a target, but I enjoy life. The only thing I've eliminated completely is alcohol.
I know of diabetics who cannot give up on sugary treats with full knowledge of the consequences of their behavior, people who have seen others in the family lose eyes, limbs, kidneys and life to the disease. Not a single one of them will consume a block of cheese or butter if one were to set these in front of them. Or a plate of diced carrots or cucumbers. It is always the chocolates and chips and the cookies and the ice cream and the biscuits.
Over the last two decades, I have been 128 kg at my peak. I have also been 93 kg. I have noticed that carbs absolutely wreck my ability to maintain weight. You lose the will to say no to food.
I am in India. Festivals start in September and continue for the next few months. It is an unending caravan of carb-heavy food. I can very easily put on 10 kg in those months. 70K excess calories in 2-3 months is not a lot. This does not happen with high fat food, because you cannot eat those in large quantities. They have high satiety value.
> Physical activity has little effect on my weight change
The human body is insanely adaptive. The natural impulse, I believe, is to conserve energy. For different people, it will respond to continuous over- and under-eating as well as over- and under-exertion in different ways.
People should do what works for them.
> Physical activity has little effect on my weight change.
Those two statements appear to be contradictory?
I've switched to the keto diet for other health reasons --I never had any weight issues, and my weight didn't change-- but I never feel as hungry as I used to. But eat a square of chocolate and the hunger comes back.
This happens with sugary drinks, but also with solid food, such as cake.
Sure, once you see your weight go up, you can adjust. But adjusting is difficult, and I think this is a contributing factor to the weight problems people have.
