Is Slim Coffee Booster keto-friendly?
Its listed ingredients are mostly fibres and plant extracts, which tend to be low in digestible carbs. Resistant dextrin is a fibre, but some of it can be partly digested. Without a nutrition panel from the seller, we can't give a carb figure.
If you're following a looser low-carb plan, it may fit easily. If you're tracking every gram, read the label first.

Frequently asked questions
Is coffee keto?
Yes. Black coffee has almost no carbohydrates.
Is Slim Coffee Booster keto?
The seller hasn't published carb content. It's fibre-based, so it may suit low-carb eating, but check the label for strict keto.
What's the best keto coffee in Australia?
It depends on your goal. Black or MCT coffee is simplest; an add-in like Slim Coffee Booster suits people who want added fibre.
Does keto coffee help weight loss?
Fat-added coffee doesn't burn fat itself. Any weight change comes from your overall eating pattern.
Can I drink keto coffee every day?
Most healthy adults can, within about 400 mg caffeine a day, but watch the extra kilojoules from butter or oil.
Does Slim Coffee Booster kick me out of ketosis?
We can't say without a carb count. Check the pack label.
