How to start keto without the guesswork

Keto is one of several approaches Macrovelo supports — Mediterranean, a balanced deficit, and others sit alongside it. If you chose keto because it fits how you like to eat, this guide is for the first week, not a claim that everyone should go low-carb.

Starting keto is less about willpower and more about structure: knowing your macro targets, planning meals ahead, and having a quick way to check whether a plate fits your day.

Focus on net carbs first

Most people on keto aim for roughly 20–50g net carbs per day, depending on activity and goals. Net carbs = total carbs minus fiber (and sometimes sugar alcohols, depending on your approach).

Before you overhaul everything, pick one week where you:

  1. Log what you eat for three days.
  2. Identify hidden carbs (sauces, drinks, snacks).
  3. Swap the highest-impact items first.

Build a repeatable meal rotation

You do not need 21 unique dinners every week. A small rotation of breakfasts, lunches, and dinners makes shopping and cooking easier:

  • Protein anchor (eggs, chicken, salmon, beef)
  • Low-carb veg (leafy greens, broccoli, zucchini)
  • Healthy fat (olive oil, avocado, cheese in moderation)

If keto is the program you chose, Macrovelo can build that week from your quiz answers — meals, workouts, and a place to log what you ate — so you are not staring at a blank calendar on Sunday night. Training days and quieter days can share one grocery list.

Use photos when labels lie

Restaurant portions and mixed plates are where keto plans break down. A photo scanner gives you a directional verdict on net carbs when nutrition labels are missing — useful as a guide, not a medical measurement.

What to do next

If keto is the program you want to try, take the Macrovelo quiz. You will get a personalized plan, a macro summary, workouts, logging, and tools to swap meals when life happens. If keto is not a fit, the same quiz can route you to another approach.
