I drink diet soda but analyze: is it preventing weight loss? Map diet soda consumption and effects: insulin response, gut health, cravings. Calculate: if artificial sweeteners affect insulin or gut bacteria, what's the impact? Show me the research: what studies show about diet soda and weight. Give me the elimination test: cut it for 30 days, measure changes. Include: whether diet soda is affecting me, if artificial sweeteners are problematic, and what to drink instead.
