Got Hashimoto’s? Diet sodas can prevent weight loss
If you regularly drink diet soda and use artificial sweeteners because you think it will help you lose weight, you’re unwittingly sabotaging your efforts. Sure, artificial sweeteners like sucralose, saccharine, and aspartame save on calories, but a recent Israeli study shows they can skew the composition of gut bacteria, or our microbiome in a way that promotes obesity and diabetes. If you’re working to manage your Hashimoto’s as well as your weight, diet sodas can work against you.
We’re increasingly learning about the trillions of bacteria that live in the gut, weighing in at 3 to 4 pounds, and the profound influence they have on human health and behavior. In addition to providing nutrients and aiding in the digestive process, gut bacteria also influence moods, behavior and mental health; immune function; energy levels; and how well we burn or store fat.
Our microbiome consists of beneficial and harmful bacteria. We carry a diverse array of bacteria –- hundreds of varieties –- and the proportions of these bacteria can play a role in how our body, brain, and even personality function. A healthy composition of bacteria is also vital to managing autoimmune diseases such as Hashimoto’s hypothyroidism.
Unfortunately, as promising as the idea of calorie-free drinks sound, they skew the balance of bacteria in the gut toward high blood sugar. This in turn promotes insulin resistance (pre-diabetes), fat storage, and chronic inflammation. In the study this phenomenon was referred to as glucose intolerance. Together these factors sabotage not only weight loss but also your ability to manage Hashimoto’s hypothyroidism.
Artificial sweeteners promote high blood sugar
The study began by looking at groups of mice that were given plain water, water with sugar added, or water with an artificial sweetener added. After 10 weeks the groups given the artificial sweeteners consistently showed high blood sugar, regardless of whether the sweetener used was saccharine, aspartame, or sucralose. Even a group of mice given a high-fat diet and sugar water maintained healthy blood glucose levels while the group given a high-fat diet and artificial sweeteners did not.
To further validate the findings, researchers transplanted fecal matter from the mice given artificial sweeteners into germ-free mice. The germ-free, too, developed glucose intolerance. When scientists gave the affected mice antibiotics to kill the overgrowth of fat-promoting bacteria, their blood sugar normalized.
Studying artificial sweeteners in humans
Of course, not everyone is going to be sold on the results of a study using mice. After all, we’re not mice. So the researchers ran the study on a small group of human volunteers, all of whom showed elevated blood sugar and alterations in their gut bacteria composition after just one week.
How to cultivate healthy gut bacteria and better manage Hashimoto’s hypothyroidism
In addition to avoiding artificial sweeteners, there are other ways to cultivate your inner garden of gut flora to promote fat burning instead of weight gain. One of the best ways is to make vegetables the primary part of your diet, including cultured vegetables. Not only are they loaded with fiber, vitamins, and minerals, they promote and maintain good gut bacteria. At the same time, avoiding processed foods, sugars and sweeteners, and artificial additives will prevent the bad bacteria from taking over and exacerbating your Hashimoto’s hypothyroidism symptoms.

There is some emerging research linking artificial sweeteners to impaired thyroid function.
https://www.mdedge.com/obgyn/article/99841/pituitary-thyroid-adrenal-disorders/aace-artificial-sweeteners-tentatively
This discusses research presented at a 2015 thyroid conference that showed a correlation between people consuming artificial sweeteners and having hypothyroidism. After this research was done, the lead author (Isaac Sachmechi) started suggesting to his own hypothyroid patients to quit artificial sugar since it may be contributing to hypothyroidism. Only three of his patients accepted the challenge, and two of the three had complete remission of hypothyroidism. The connection between artificial sugar and hypothyroidism is very intriguing, despite that there is currently a lack of large studies on this topic.

This is a case study (again led by Issac Sachmechi) that showed one 52 year old woman who was diagnosed with Hashimoto’s thyroiditis after consuming artificial sweeteners for 14 years, and whose hypothyroidism quickly went away after she cut out the artificial sweeteners in 2012 (though they don’t say how quickly it went away). The authors point out that there was a long lag time (14 years) from the time she started consuming artificial sweeteners until she was diagnosed with hypothyroidism, which may make it harder for individuals and researchers to make a causal connection between the two, assuming there is a causal connection.
Amazing, thanks for sharing!
