Good to Know
Tempeh is fermented whole soybeans, so it has more carbs than tofu but also more protein. Keep the serving to a few ounces, count the carbs, and it slots into a keto day fine. Pre-marinated or glazed tempeh from the refrigerated case often adds sugar, so check the label and season it yourself when you can.
Is Tempeh Keto? The Full Answer
Tempeh contains 6.50g net carbs per 3 oz (6.50g total carbs minus 0.00g fiber). Tempeh carries about 6.5 g net carbs per 3-ounce serving, so it fits keto in modest portions rather than as a free food. It is a dense plant protein at roughly 17 g per serving, which makes it one of the more useful options for vegetarians doing keto.
On a standard ketogenic diet, most people target 20-25g net carbs per day. A single serving uses 33% of a 20g daily carb limit. Track your portions carefully and account for other carbs in your meals.
Better Keto Swaps
For fewer carbs with similar protein, firm tofu comes in under about 2 g net carbs per serving and takes on whatever seasoning you give it.
Measure Your Ketone Levels
A blood ketone meter reads beta-hydroxybutyrate from a finger prick, the marker that defines nutritional ketosis at 0.5 to 3.0 mmol/L. Urine strips measure acetoacetate instead, which drops off once you are fat-adapted. Keto-Mojo makes a blood meter.
