The whole ethos of a keto diet is to keep your macros to approximately 70% Fat, 25% Protein, and 5% Carbohydrates (Carbs) in order for your body to produce ketones as it transitions into ketosis.

This 5% of Carbs should not exceed 20 grams per day for a keto diet.

Depending on whether you are eating a lazy, dirty, or strict keto diet, will depend on how strictly you track these macros, and how willing you are to eat sugars, artificial, or otherwise.

Eating green apples on a keto diet has the potenetial to knock you out or ketosis.

In order to keep your carb consumption under 20 grams, you need to be conscious of what you are eating and stick to low-carb healthy foods, that are also low on the glycaemic index.

The reason for this is so as not to spike your blood sugar. Spiking blood sugar could knock you out of ketosis.
