People often use "low-carb" and "keto" interchangeably, but they're not the same. The difference is how far you cut carbs — and whether you reach ketosis.

Low-carb

A low-carb diet simply means eating fewer carbs than a typical diet — generally under about 130 grams a day, or less than roughly 26% of your calories from carbs (clinical reference). You eat less bread, pasta, and sugar, but you can still include some fruit, legumes, and starchy foods. It usually does not put you into ketosis.

Keto

Keto is a stricter form of low-carb — usually 20–50 grams of carbs a day — low enough to push your body into ketosis, where it runs mainly on fat (Cleveland Clinic). It's also higher in fat than general low-carb eating.

So which should you choose?

  • Keto may suit you if you want the specific effects of ketosis (steady appetite, blood-sugar control) or a structured plan, and you're willing to track carbs closely.
  • General low-carb is easier to live with long term, more flexible at restaurants and social events, and still cuts a lot of sugar and refined carbs. Many people find it more sustainable.

Neither is "better" for everyone — the best diet is the healthy one you can actually stick to. If you have a medical condition or take medication, check with your doctor before starting either.
