Best for Following a Diet Plan 2027

Why Lifesum won

A calorie target tells you how much to eat; a plan tells you what. Lifesum is built around the second idea. You choose an eating plan, and the app’s targets and suggestions follow it: more protein on a high-protein plan, a Mediterranean pattern on that one, net carbs on keto. For people who find a blank daily budget hard to fill, that framework is the easiest way into tracking. Lifesum’s clean, colourful design makes the daily feedback easy to read.

How the shortlist compares

• PlateLens takes a planning approach rather than a packaged-diet approach. Its recipe and meal planner lets you plan meals ahead, including low-carb ideas, turns the plan into a grocery list, and saves recipes for one-tap logging. You keep flexible tracking with photo, voice, barcode and typed search, and the planner sits alongside everything else.
• Carb Manager is built entirely around keto and low-carb plans, with a large recipe library.
• Noom is a program rather than a plan: daily lessons and coaching about habits.

Choosing a plan safely

Any packaged plan should suit your health, preferences and budget. Very restrictive plans are harder to sustain, and anyone with a medical condition, who is pregnant or who takes medication affected by diet should discuss changes with a clinician first.

The bottom line

Choose Lifesum if you want a diet handed to you. Choose PlateLens if you want to plan your own meals and keep one diary for everything.
