PREPARATION SUGGESTIONS
FRESH BREWED
Brew strong black or green tea, chill, and sweeten to taste with stevia or allulose—or enjoy unsweetened for a clean zero-carb option.
LEMON LIFT
Add a squeeze of fresh lemon or a slice of lime for brightness and a little vitamin C without meaningful carbs.
HERBAL COOL
Cold-steep with peppermint tea bags for a naturally cooling, caffeine-optional twist.
OVER ICE
Serve over plenty of ice with a lemon wheel; keep garnishes keto-friendly (citrus peel, herbs).
AFTERNOON FOCUS
Use a mid-afternoon glass for gentle alertness; choose decaf if you’re caffeine-sensitive.
KETO COCKTAIL
Combine with vodka, rum, or whiskey and a splash of diet lemonade for a low-carb highball.
