How does tomato fit your goals?

Tomato is a carb-dominant food, with 4.8g of carbohydrate per 1 medium (123g). That makes it a useful pre- or post-training fuel source, especially for endurance work or higher-volume strength sessions. If you're tracking for fat loss, the lever isn't avoiding carbs — it's portioning them around the parts of your day where the energy is actually used.

Diet-wise, tomato fits keto, low-carb, and vegan and vegetarian eating patterns.

Micronutrients worth noting

Beyond the macros, tomato pulls real weight on vitamin C (19% DV) per 1 medium (123g) — the kind of micronutrient density that calorie counts alone don't show.

Tracking tomato without the friction

The numbers above only help if logging is easy enough that you actually do it. Instead of searching a database every time tomato hits your plate, snap a photo in Bento Bunny — the app recognises the food, estimates the portion, and adds the macros for you. No subscription needed for core tracking.
