A mother of three’s decision to quit diet soda, consuming as many as eight cans daily, has sparked a conversation about the potential impact of artificially sweetened beverages on cravings and overall health. Hiliary McKay, a stay-at-home mother, began her journey to eliminate the drinks on January 21, 2026, replacing them with water while maintaining the habitual act of drinking from a cup.
McKay’s daily intake, amounting to several liters of diet soda each month, had become a long-standing habit. “Aside from my pregnancies, I don’t remember drinking water every day during my adult life,” she stated, reflecting on her reliance on the beverages.
After consulting with her doctor, McKay proceeded with a complete cessation of diet soda, despite being advised of potential withdrawal symptoms like headaches, and fatigue. The initial days proved challenging, marked by fatigue, intense cravings, and frustration. Although, McKay found the symptoms less severe than anticipated.
Within weeks, McKay reported improvements in sleep quality, mood stability, and skin clarity, alongside a general sense of well-being. She also observed a gradual decrease in soda cravings, which now only surfaced during unusual events.
Nutritionist Pauline Pied explains that diet sodas, often containing artificial sweeteners like aspartame, can influence the gut microbiome and eating behavior. Even without sugar, these beverages activate the brain’s reward pathways associated with sweetness. This activation can create an expectation of sugar that isn’t fulfilled, potentially perpetuating sugar cravings and snacking.
“In the medium term, stopping diet sodas often helps reduce cravings and those overwhelming desires for sugar,” Pied said.
Pied also highlighted the benefits of increased water intake. Adequate hydration supports overall bodily functions.
The impact of artificial sweeteners on gut health is another key consideration. Aspartame and certain polyols can disrupt the gut microbiome and accelerate transit time in sensitive individuals. Eliminating these beverages can allow the gut to regain stability, potentially improving digestion, energy levels, and overall dietary habits.
Pied cautioned against using diet sodas to suppress appetite, noting that they provide a temporary feeling of fullness without delivering actual energy. This can lead to continued hunger signals and subsequent snacking, maintaining a connection to sweet tastes even in the absence of sugar.
McKay is now sharing her experience on social media, documenting her transition and encouraging others to consider their own relationship with diet sodas. She plans to continue medical follow-up to support her progress.
Pied emphasizes that occasional consumption of diet soda is unlikely to be problematic, but making it a daily habit can impact the microbiome, cravings, and overall dietary patterns. She advocates for prioritizing water as the primary daily beverage, reserving soda for occasional enjoyment.
