I read the referenced citations. Nothing provided evidence that using an artificial sweetener like sucralose would have any direct impact on diet.
From the sidebar FAQ on your website:
1) Many people avoid sugar to lose weight, only to introduce potentially harmful chemicals into their diets in the form of sugar-free food products.
Fine, saccharin when fed in enormous quantities to rats has shown a propensity to be a carcinogenic agent. Show me the evidence where sucralose or aspartame have. Otherwise, define "harmful."
2) Overstimulation of sweet flavors from artificial sweeteners can cause stalled weight loss and sometimes weight gain.
Both the peer-reviewed references you cited stated that this was not due to the artificial sweeteners themselves but, rather, due to people overcompensating their energy intake by eating more of other foods.
3) Artificial sweeteners may play a role in tumor development and other forms of cancer, although there is a lot of controversy about this claim in the scientific community.
Yes, as I stated, saccharin in enormous (many times the body weight of the rats forced to ingest it constantly) decades ago, which is why products like aspartame and sucralose were developed. Show us the peer reviewed scholarly research (not just someone's opinion) that proves the causation between ingesting these later products and cancer. Otherwise, stop pretending at science. Oh, and isn't this a restatement of your first item ("harmful chemicals")? Why the pretend list, too?
4) Researchers have found that the test subjects who drank artificially sweetened beverages consistently had higher BMIs than those who didn’t.
Again, non-causal as the articles actually wrote, except as a person overcompensates with more energy (caloric) uptake from other foods. If you disagree, please demonstrate how something ingested that contains no calories can "magically" add an energy component.
I find the constant "pop-culture" continuation of your sweetener fantasies disappointing. There are so many holes in your presentation on sweeteners, both scientific and contextual, to question your entire rationale in every other area you profess to "help" people.
