Honey isn’t keto. It’s mostly fructose and glucose, which is sugar with better PR.
But honey on keto really comes down to one question: how much are you actually having? A teaspoon in a smoothie is a very different thing from a tablespoon on toast. Here’s the carb maths, what I do with it, and what to buy if you’d rather keep it at zero.
Honey on keto: the carb maths
Carbs vary by brand and how much the honey has been processed, but you’re looking at roughly 78g carbs per 100g. In keto terms, that’s a lot. In real life, nobody eats 100g of honey, so here’s the version you can use:
- 1 teaspoon: about 5g carbs
- 1 tablespoon: about 20g carbs
- 100g: about 78g carbs
A teaspoon stirred into a smoothie barely registers in a day’s carbs. A tablespoon is a proper chunk of them. A teaspoon in your coffee counts the same as one in a smoothie: the carbs don’t check which drink they’re in. Where your own line sits depends on whether you’re eating strict keto or something more flexibly low carb, and I’ve sorted out the difference between keto and low carb if that’s still fuzzy.
Honey does contain small amounts of amino acids, minerals and antioxidants. At a teaspoon, they are small amounts. I wouldn’t count honey as a multivitamin.
Raw honey vs processed honey
Processed honey is usually heated and filtered. Raw honey is less processed. Heating can change some of the compounds in honey, but whether that makes any difference at one teaspoon isn’t something the research has settled. Honey has been used in traditional medicine for centuries, and there are plausible reasons why, but plausible isn’t proven.
When I lived in Adelaide I was stuck with terrible hay fever, and a naturopath told me to eat local raw honey so my body would get used to the pollen. I don’t know how much validity that has. Trialling honeys from the Adelaide Hills and the Barossa wasn’t exactly a chore, though.
Some brands infuse raw honey with mushroom extracts. life cykel’s Reishi Honey lists a 7g serve (a smidge over a teaspoon) at 5.6g carbs, and it doesn’t change the flavour. The nerdy question is how much extract you get per serve and whether that matches anything studied. Check the label before you pay extra for it.
Supermarket honey
Price and quality vary hugely on the supermarket shelf. Flip the jar: the ingredients should say honey and nothing else, and the label should tell you where it’s from.
If comparing labels in the aisle is more than today’s spoons will cover, pick one you recognise and move on. Honey is not a decision that needs a spreadsheet.
Keto honey substitutes
There are some reasonable honey substitutes that behave a bit like honey in cooking.
Keto-friendly doesn’t mean nutritious, though. Most substitutes are there for flavour and texture, not nutrition. That’s fine. It’s just worth knowing when you choose.
The one I’d point you to is Nature’s Hallow Keto Honey Substitute. Per the label it has no sugar, zero carbs and zero calories. It contains xylitol and gums, which is why it caramelises and behaves more like the real thing in cooking. Some people spread it on toast. Each to their own.
Two warnings about xylitol:
- It is toxic to dogs in any amount. Keep it well out of reach, and ring a vet straight away if a dog has eaten some.
- It can have a laxative effect for some people.
What I actually do
Honey is sugar, so it raises blood glucose and your insulin response. Eating it with other food, like in a smoothie or a recipe, tends to soften that. Whether it knocks you out of ketosis is very individual, and it’s rarely down to a single teaspoon on its own. If you’re tracking ketones or glucose for medical reasons, your GP or dietitian is the right person to ask.
For me, I almost always choose real food over a synthetic substitute. I buy raw honey, and it nearly always ends up in a recipe or a smoothie alongside other ingredients. At 5.6g carbs a serve, it fits within my macros and I like it, so I’m not going to fuss over it. That’s what works for me. Yours might land somewhere else.
One practical tip: measure a teaspoon once so you know what 5g looks like, then stop measuring. Maths is an expensive use of spoons. Maths before coffee costs double.
If macros still feel like homework, how macros fuel our body is the version I wish I’d had at the start.
