Some other things to consider regarding blood sugar management:
Too Much Food In One Sitting
can lead to hormonal fluctuations, increased blood sugar levels, and inflammation, all of which can contribute to acne breakouts. Intermittent fasting, extended water fasts, and not eating big meals before bed could help.
Smoothies
This is related to the above. Avoid blending lots of high glycemic fruits/veg into smoothies as this can break the fiber which may result in sugar being absorbed more quickly.
