Guinness - 20 oz Imperial Pint (1 oz) and Guinness - 20 oz Imperial Pint (1 oz)

Reduce the serving size: a 20 oz imperial pint is large, so choose a smaller pour or split one pint rather than having two.

Avoid drinking on an empty stomach; have it with a balanced meal containing protein, healthy fats, and non-starchy vegetables, such as grilled chicken or tofu with a salad.

Skip sugary mixers, sweet snacks, and refined-carb foods alongside the beer, since these can compound the rise.

Alternate each beer with water or sparkling water to slow intake and support hydration.

Take an easy 10–20 minute walk after drinking, if it is safe for you, to help your muscles use circulating glucose.

Check your glucose response over the next several hours; alcohol can sometimes cause a delayed drop, especially if you use insulin or glucose-lowering medication.
