4. Nutrition & Meal Planning

1 The Interactive Planning Sliders

At the top of the widget, you have five vertical sliders that allow you to fine-tune your daily plan:

• Active Calories — Set how many calories you plan to burn through exercise today.
• Calories — Your total daily energy intake goal.
• Carbs, Protein, & Fat — Specific gram targets for each macronutrient.

These sliders are "Smart." For example, if you increase your "Active" calories, the widget uses your profile (age, weight, height, gender) to automatically adjust your "Total Calories" target to match your increased energy needs.

2 Activity Modes

The widget allows you to toggle between two distinct calculation modes that change how your targets are generated:

• Iron Set Mode High Performance — Optimized for active individuals and athletes using specific high-performance formulas.
• Decent Mode Standard — A more passive mode designed for maintenance or standard lifestyle activity.

3 Meal Objectives

Below the sliders is a grid of objectives (e.g., "Mass Gain," "Cutting," "Maintenance"). Selecting an objective instantly re-calculates your macro targets.

4 Real-Time Nutrient Balancing

The widget ensures that your "Calories" and "Macros" stay in sync. If you manually adjust the Protein slider, the widget internally recalculates the energy balance. It ensures the math always adds up so your plan is scientifically sound:

5 Profile Integration

The widget is reactive to your user profile. Whenever you update your weight, age, or gender in your profile settings, this widget automatically refreshes its recommendations to ensure your targets remain accurate for your current body composition.

6 Tilt-to-Scroll

Like other parts of the IronSet interface, this widget supports Tilt Interaction. If your hands are busy, you can tilt your device to scroll through the planning options, ensuring you can adjust your meal plan even in the middle of a task.

1 The Energy & Nutrition Pager (Top)

The top section features a 4-page interactive carousel that visualizes different aspects of your health:

• Energy Balance (Calorie Rings) — The most critical view. It shows three concentric rings:
  • Outer Ring (Green/Blue) — Your total calories burned, split into Passive (what your body burns just staying alive/BMR) and Active (exercise/movement).
  • Inner Ring (Red/Yellow) — Your Calorie Balance. It visually displays if you are in a Surplus (eating more than you burn) or a Deficit (burning more than you eat).
• Macro Progress — Displays three rings (Orange for Carbs, Red for Protein, Yellow for Fats) showing how close you are to your daily targets.
• Daily Summary Card — A quick text-based summary of your Goal, BMR (Basal Metabolic Rate), total Consumed calories, and the remaining Balance for the day.
• Micronutrients Tracker — Tracks your intake of vitamins and minerals against recommended targets.

2 The AI Food Scanner Gemini AI

This is the "magic" button. By tapping AI Scanner, you can take a photo of your meal. The app uses Google Gemini AI to:

• Identify the food in the image.
• Estimate the weight/portion size.
• Automatically calculate the Carbs, Protein, and Fats.
• Suggest a meal name and populate the inputs for you, saving you from manual data entry.

3 Precision Manual Logging

If you prefer manual entry or need to tweak the AI's results, the widget provides high-precision controls:

• Vertical Macro Sliders — Four dedicated sliders for Weight (grams), Carbs, Protein, and Fats. Slide your finger to adjust values quickly or use the + and − buttons for single-gram precision.
• Portion Control — A "Single Serving" toggle allows you to quickly switch between logging a specific weight in grams or a standard "one serving" unit.
• Meal Identity — A text field to name your meal (e.g., "Post-Workout Shake") so you can recognize it in your history.

4 Interactive Feedback & Hints

• Visual Laps — The rings support "Multiple Laps." If you exceed your goal (e.g., eat 150% of your protein target), the ring will start a second, darker-colored lap to show you've gone above and beyond.
• Guided Navigation — The app uses pulsing green arrows to remind you that you can swipe horizontally for more data or scroll down to see your history.
• Logging Confirmation — When you tap Log Meal, the data is instantly saved to your history and the top rings update in real-time to reflect your new totals.

5 Meal History (Bottom)

Scrolling down reveals a chronological list of everything you've eaten today. This allows you to review your choices, see the specific breakdown of past meals, and stay accountable to your plan.

6 Tilt Navigation

Just like the workout widgets, the Energy Widget supports Tilt Interaction. You can tilt your phone to scroll through your meal history or adjust values, keeping the interface accessible even when you're busy in the kitchen.

1 Week-Based Navigation

At the top of the widget, you'll find a navigation bar that organizes your history by week:

• Weekly View — It displays a label such as "Week of Oct 21," showing you exactly which 7-day period you are viewing.
• Jump Between Weeks — You can use the ◀ and ▶ arrows to browse previous weeks. The interface is smart — it won't let you navigate into the future (beyond the current week).
• Automatic Focus — Whenever you open a week that includes the current day, the widget automatically scrolls to "Today" so you don't have to search for your most recent entries.

2 The Daily History Grid

The heart of the widget is a two-column grid that displays Meal Day Cards:

• Visual Summary — Each card represents a single day. It shows the date and a summary of the meals consumed on that day.
• Data Accuracy — It pulls directly from your meal history, ensuring that every snack or meal you've logged (manually or via AI) is accounted for.
• Empty States — If you didn't log anything on a specific day, the card remains as a placeholder, helping you identify gaps in your tracking.

3 Integrated Tilt Interaction

Consistent with the rest of the IronSet experience, this widget is optimized for hands-free use:

• Tilt-to-Scroll — You can scroll through your weekly grid simply by tilting your phone. The application uses your device's sensor data and translates your physical movement into smooth vertical scrolling, which is particularly useful if you are reviewing your history while multi-tasking.

4 Technical Intelligence

1. Smart Grouping — The widget automatically handles the complex logic of grouping individual meal timestamps into their respective calendar days based on your local time zone.
2. State Persistence — It uses run-time persistence for your current week selection, meaning if you navigate away from the widget and come back, it remembers exactly which week you were looking at.
