What im sweetening my plain yogurt with:
Studies on allulose, a "rare sugar," show it is a promising, low-calorie sweetener that does not significantly increase blood glucose or insulin levels. Research indicates it can improve glycemic control, promote weight loss by reducing fat accumulation, and enhance insulin sensitivity. It is widely considered safe, though more long-term human studies are needed. [1, 2, 3, 4, 5]
Key Findings from Allulose Research:
• Blood Sugar and Insulin Regulation: Studies consistently show that allulose does not spike blood glucose. It has been shown to reduce postprandial (after-meal) blood sugar levels when consumed with other carbohydrates. A recent study found that for every gram of allulose added to carbohydrates (like rice), there was a corresponding $1\%$ reduction in blood glucose levels, notes Toronto Metropolitan University (TMU).
• Weight Management and Obesity: Animal and human studies indicate that allulose helps combat obesity. It acts by reducing fat cell maturation, decreasing fat accumulation, and potentially increasing energy consumption. Studies on rats demonstrated that allulose supplementation (up to 12 weeks) lowered body weight gain and abdominal fat, according to National Institutes of Health (.gov) and MDPI (https://www.mdpi.com/2072-6643/17/12/2050).
• Mechanisms of Action: Allulose increases the release of glucagon-like peptide-1 (GLP-1), a hormone that helps regulate appetite and glucose, says National Institutes of Health (.gov).
• Metabolic Health: Research suggests allulose can ameliorate diet-induced insulin resistance and liver triglyceride accumulation. It may improve macrophage function and reduce inflammation in adipose tissue.
• Human Study Limitations: While animal studies are robust, most human trials have been short-term or involved small sample sizes.
• Safety: The FDA has approved allulose and generally considers it safe (GRAS), according to UT MD Anderson (https://www.mdanderson.org/cancerwise/is-allulose-a-healthy-sugar-substitute.h00-159779601.html) and Healthline (https://www.healthline.com/nutrition/allulose). [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
Common Findings Across Studies:
• Sweetness: It provides about $70\%-80\%$ of the sweetness of sugar, say Healthline.
• Calorie Content: It has almost no calories (roughly $0.2-0.4$ kcal/g), or about $10\%$ of the calories in sugar, says Healthline.
• Metabolism: $70\%-80\%$ of consumed allulose is absorbed in the small intestine and excreted unchanged in urine, not metabolized for energy, say Cambridge University Press & Assessment (https://www.cambridge.org/core/journals/british-journal-of-nutrition/article/allulose-in-human-diet-the-knowns-and-the-unknowns/74020152A1262DF4D7942A4DB54B6E37) and Healthline.

Background/Objectives: The consumption of fructose-sweetened beverages, especially when combined with a high-fat (HF) diet, substantially contributes to obesity, diabetes, and metabolic dysfunction-associated steatotic liver disease. Ectopic fat accumulation in skeletal muscles is a critical factor....
