This question comes up because vegetable glycerin — one of e-liquid's two main base ingredients — is also a recognized food ingredient with a caloric value on its own. Whether that translates into meaningful calorie intake from vaping is a different question, and it comes down to how the ingredient is actually consumed.
Vegetable glycerin (VG) is one of e-liquid's two base liquids, and it's also used across a range of food products, where it does carry a caloric value in that context, generally comparable to other sugar alcohols used in food.
Vaping delivers vapor to the lungs rather than the digestive system, which is a fundamentally different route of exposure than eating or drinking something containing the same ingredient. Caloric content as commonly discussed is based on digestive absorption, a process vaping doesn't involve in the same way.
The actual amount of VG vaporized and inhaled per vaping session is a small fraction of the quantity involved in eating or drinking a comparable food product containing the same ingredient — a meaningfully different scale of exposure regardless of the delivery-route question above.
This is a description of what's compositionally in the liquid, not a health claim or dietary recommendation in either direction. Anyone with a specific health or dietary question is better served speaking with a healthcare provider than treating general ingredient information as personal guidance.
Flavoring makes up a small fraction of an e-liquid's overall composition compared to the VG/PG base, so it's not a major factor in the ingredient breakdown either way.
Not typically — e-liquid isn't regulated or labeled as a food product, so it doesn't carry a nutrition facts panel the way packaged food does.
Nicotine is present in extremely small quantities relative to the overall liquid volume, and isn't a meaningful factor in this specific question compared to the base liquid ingredients.
