Personalized Fitness And Nutrition Plan

What it does

This prompt instructs the AI to act as a personal trainer and, using the user’s provided demographics, location, activity level, and goal details (including optional target weight, body fat percentage, preferred foods, and output language), calculate TDEE, set a daily calorie target, estimate the timeline to reach the goal, and produce a practical daily meal plan and exercise recommendations, along with key notes to help achieve the target safely and effectively.

Inputs

textInputs

Pass each text input using --input <key>=<value> flags.

Models and options

This skill's modality is: text.

To discover which model values you can use (and which options keys/values are valid for each model), run:

betterprompt resources --models-only --json

Then filter the returned JSON array to entries where modality is "text".

How to run

Step 1: Collect inputs

First, run betterprompt resources --models-only --json and filter to modality: "text" to discover valid models and available options:

betterprompt resources --models-only --json

Use only the models and option values that appear in the filtered results.

Then collect all inputs from the human:

• Required text inputs:
  • Sex
  • City
  • Target
  • Activity_level
  • Body_fat_percentage
  • Speed_to_reach_the_goal
• Optional text inputs (use defaults if not provided by the human):
  • Age (default: 25)
  • Height_cm (default: 185cm)
  • Weight_kg (default: 80kg)
  • Output_language (default: English)
  • Target_weight_kg (default: 75kg)
  • Foods_that_are_easy_to_find (default: Rice, chicken breast, vegetables, eggs, oats, brown rice, unsalted butter, olive oil, sweet potatoes, milk, and suggest some types of meat)
• Optional: model and options.
  • Present the human with the default model gpt-5 and its available options. Look up gpt-5 in the betterprompt resources output (filtered to modality "text") and show its availableOptions as: key: val1, val2 (default), val3 | key2: .... Mark a value (default) if it matches these defaults: {}.
  • If the human does not specify, defaults are used: model gpt-5, options {}. Other models from the resources call are also available.

If any required text input is missing, ask the human for what's missing. Do not assume or fabricate values.

Step 2: Run via BetterPrompt CLI

Use the frontmatter's name as the positional argument (for this skill, use personalized-fitness-and-nutrition-plan).

Command form:

betterprompt generate personalized-fitness-and-nutrition-plan \
  [--input <key>=<value>] \
  [--model <model>] \
  [--options <options JSON>] \
  [--json]

Notes:

• Pass each text input as a separate --input <key>=<value> flag.
• If the human does not mention a model, omit --model and BetterPrompt will use the default model: gpt-5.
• If the human does not mention options, omit --options and BetterPrompt will use the default options: {}.
• If the run times out, the response will include a runId you can use to fetch the result later.

Example (using defaults shown above):

betterprompt generate personalized-fitness-and-nutrition-plan \
  --input Age=25 \
  --input Sex=Male \
  --input City=<value> \
  --input 'Target=gain weight' \
  --input Height_cm=185cm \
  --input Weight_kg=80kg \
  --input 'Activity_level=Light (light exercise 1-3 days/week)' \
  --input Output_language=English \
  --input Target_weight_kg=75kg \
  --input Body_fat_percentage=<value> \
  --input Speed_to_reach_the_goal=Fast \
  --input 'Foods_that_are_easy_to_find=Rice, chicken breast, vegetables, eggs, oats, brown rice, unsalted butter, olive oil, sweet potatoes, milk, and suggest some types of meat' \
  --model gpt-5 \
  --options '{}'
