WHY IT'S NOT KETO-FRIENDLY
- High sugar content makes regular consumption problematic
- Best reserved for occasional mixers; prefer sugar-free tonic
- 9g net carbs per 100ml adds up quickly in cocktails
- Sugar-free alternatives are widely available
- Keep portions small to maintain ketosis
- Use seltzer/club soda to dilute carb load

QUININE WATER SPRITZER
Stretch a small amount of sugar-free tonic with sparkling water for lower carb impact.
