Por qué — la lógica de calorías e insulina
Aspartame, sucralose, and acesulfame-K are essentially calorie-free. Research on their effect on insulin is mixed: some controlled studies find no insulin response; others find small cephalic-phase effects from the sweet taste. Sucralose in particular has been shown to trigger a cephalic-phase insulin response in some populations.
¿Depende de tu objetivo de ayuno?
For calorie-count-based weight-loss fasting, occasional use is unlikely to matter. For metabolic fasting, the contested insulin signal is worth noting. For strict autophagy fasting, avoiding all non-water substances is the conservative approach. The science does not definitively resolve this — the prudent answer is that plain water and unsweetened beverages are safest.
Preguntas frecuentes
- Does aspartame break a fast?
- Aspartame is calorie-free and most studies show no insulin effect. For weight-loss fasting it is generally considered safe; for strict autophagy, plain water is the safest option.
- Does sucralose break a fast?
- Sucralose is calorie-free but may produce a small cephalic-phase insulin response. Its effect on strict fasting is debated — treat it as 'depends' and prefer plain beverages if your goal is autophagy or metabolic precision.
