Why do people switch from FatSecret?

Common reasons are ads on the free tier, the fact that net carbs aren't the headline metric, and wanting faster logging. Keto and low-carb users in particular want an app that leads with net carbs instead of general calories.

Is there a free FatSecret alternative with no ads?

Yes. CarbMeNot tracks net carbs and macros free with no ads. Cronometer and Carb Manager also have free tiers, though some features are paid; MyFitnessPal's free tier shows ads like FatSecret's.

Which FatSecret alternative has the best food database?

MyFitnessPal and Cronometer have very large databases. FatSecret's own database is one of the biggest, so if database size is your main reason to leave, choose MyFitnessPal; if you're leaving for keto focus, choose CarbMeNot and use AI photo logging for foods without a barcode.

Does CarbMeNot import my FatSecret data?

There isn't a one-tap FatSecret import today. Most people switch by setting their carb and calorie goals in the new app and logging forward from that day; your recent foods build up quickly, especially with AI photo logging and barcode scanning.

5 Best FatSecret Alternatives for Keto (2026)

The best FatSecret alternative for keto is CarbMeNot — it makes net carbs the default number for free, logs meals with AI photo capture, and has no ads. FatSecret is a capable general calorie counter with a huge database and cross-platform apps, but keto and low-carb users often leave because net carbs aren't the headline and the free tier shows ads. Below are the five best alternatives, ranked by how well they fit a low-carb workflow.

Why switch from FatSecret?

FatSecret does a lot well, but three things push keto users to alternatives: ads on the free tier, net carbs that aren't the default view (you track total carbs and fiber and compute the rest, per Harvard's explanation of fiber), and a general-purpose layout when you only care about staying under a carb limit.

1. CarbMeNot — best overall alternative

CarbMeNot is built for low-carb: net carbs are the headline number on every food and your daily total, free, AI photo logging keeps entry fast, and there are no ads. It's the most direct upgrade if you left FatSecret for keto focus. iOS-first today, Android in progress.

2. Carb Manager — most features

A mature keto tracker with meal plans, recipes, and a large database, cross-platform. Some features are Premium.

3. Cronometer — most accurate

Precise, vetted nutrition data and full micronutrient tracking, with a clean free tier and no ads.

4. MyFitnessPal — largest database

If you're leaving FatSecret but want a comparably huge database, MyFitnessPal is the closest match — just note net carbs are Premium and the free tier has ads.

5. Lifesum — guided plans

Lifesum wraps tracking in structured diet plans and a polished interface, good if you want more hand-holding.

Which should you pick?

Choose CarbMeNot if you left FatSecret for a keto-first, ad-free app with net carbs free and AI logging.
Choose Carb Manager or Cronometer for depth or accuracy.
Choose MyFitnessPal if database size is your main priority.

Key takeaways

People leave FatSecret mainly for ads, non-default net carbs, and speed.
CarbMeNot is the best keto alternative: net carbs free, no ads, AI logging.
For raw database size, MyFitnessPal is the closest FatSecret substitute.

If you're switching for keto or low-carb, CarbMeNot is free on the App Store and tracks net carbs out of the box.
