Keto vs. low-carb: what's the difference?

The main difference is carb level and ketosis: a ketogenic diet keeps carbs very low (about 20–50g net carbs per day) specifically to reach ketosis, while a general low-carb diet simply reduces carbs (often 50–150g per day) without necessarily producing ketones. All keto is low-carb, but not all low-carb is keto.

Side-by-side comparison

	Keto	General low-carb
Net carbs/day	~20–50g	~50–150g
Goal	Reach ketosis	Reduce carbs/sugar
Produces ketones?	Yes	Usually no
Fat intake	High	Moderate–high
Flexibility	Stricter	More flexible
Tracking	Net carbs + ketones	Net carbs

Pros and cons

Keto

• Pros: appetite control, steady energy, measurable feedback via ketones.
• Cons: stricter; an adaptation period ("keto flu"); needs more planning.

General low-carb

• Pros: easier to sustain, more food variety, still cuts sugar and refined carbs.
• Cons: no ketosis benefits; results can be slower or less consistent.

Which should you choose?

• Choose keto if you want the specific benefits of ketosis, like strong appetite suppression, and you're willing to track more closely.
• Choose low-carb if you want a flexible, sustainable way to cut sugar and refined carbs without the strictness of staying in ketosis.

Many people start low-carb and tighten into keto once they're comfortable — or cycle between the two.

Track either approach in CarbClue

CarbClue works for both: set a carb budget anywhere on the spectrum and log net carbs to stay on target. If you go full keto, add ketone readings to confirm you've crossed into ketosis.
