How it works

Three steps, in this order

The same loop every week. Do it once properly and the rest is repetition.

  1. 01
    Step 1

    Pick your daily carb limit

    Start with a net carb target that fits your body and your goal — not a number you saw in a caption. The calculator shows the arithmetic so you can defend the figure.

    Set your target
  2. 02
    Step 2

    Build the week around it

    Log seven days against that target and get a week total plus an honest daily average that ignores the days you didn't record.

    Open the meal planner
  3. 03
    Step 3

    Check the plate before you eat

    Weigh what you're actually cooking, total the dish, and divide by the servings you'll really take. That is the number that matters.

Editorial standards

How these numbers are made

KetoLeanHub is an independent educational publication, written by an editorial team and not individually reviewed by a clinician. That is why we publish the method alongside the answer — so you can check it yourself.

  • One source for every carb figure

    Carbohydrate and fiber values come from USDA FoodData Central, per 100 g. Nothing is quoted from a blog, a package claim, or a memory.

  • Net carbs, shown working

    Net carbs = total carbohydrate − fiber. Every calculator displays that subtraction rather than hiding it behind a result.

  • Gaps are labelled, not filled

    Where a value cannot be supported — a generic sauce, a brand-specific sweetener — we say so instead of publishing a guess.

  • Corrections in the open

    Pages are rechecked on a schedule and when sources change. Anyone can report an error and get a dated note on what changed.

Keto questions, answered

The most common questions beginners ask — answered plainly, without the jargon.

For most healthy adults, the ketogenic diet is safe when followed correctly. It's been studied for decades and used medically since the 1920s. However, it's not right for everyone — pregnant or nursing women, people with certain liver or pancreatic conditions, and those with a history of disordered eating should avoid it. Always check with your doctor before starting, especially if you take medication for diabetes or blood pressure.

Most people lose 5–10 pounds in the first 1–2 weeks, largely from water weight as your body burns through glycogen stores. After that, a healthy, sustainable rate is 1–2 pounds per week. Weight loss is rarely linear — expect stalls and whooshes — so focus on trends over time rather than the daily scale number.

Keto flu is a collection of symptoms — headaches, fatigue, irritability, brain fog, and muscle cramps — that hit some people during the first week as your body adapts to burning fat instead of carbs. It's caused by dehydration and electrolyte loss, not an actual illness. The fix is simple: drink plenty of water and replenish sodium, potassium, and magnesium.

Not forever, but it helps a lot in the beginning. Tracking your carbs (keeping under 20–30g net daily) is the most important part. As you get a feel for portion sizes and which foods fit, most people can transition to a more intuitive approach. Use a tracking app for the first 2–4 weeks to build the habit.

Absolutely. While it's more challenging without meat, a vegetarian keto diet is totally doable by focusing on eggs, full-fat dairy, tofu, tempeh, nuts, seeds, avocados, and low-carb vegetables. Just watch your protein intake and make sure you're getting enough variety. A vegan keto diet is possible too, though it requires more planning.
