Fever-Tree Light Tonic Water

Fever-Tree Light Tonic Water should be avoided on keto because it is very high in net carbs (9.12g of net carbs per 240ml serving).

It is important to limit your net carb consumption to 20g - 30g per day to stay in ketosis. You can calculate your ideal daily net carb allowance by using this keto macros calculator.

As an alternative, you may look for other sparkling water brands that are low in net carbs.

Fever-Tree Light Tonic Water contains high-glycemic sweeteners like sugar and fructose. These sweeteners can raise your blood sugar level and prevent you from reaching ketosis.

As an alternative, you may look for other sparkling water brands that use keto-friendly sweeteners like stevia, monk fruit, or erythritol.
