Procedure

1. Assess Budgetary Constraints: Identify the user's current spending concerns, whether related to gym memberships, specific supplements, or grocery costs.
2. Optimize Protein Intake with Staples: Prioritize the following cost-effective protein sources when suggesting meals or searching for foods:
   • Plant-Based: Lentils, chickpeas, and dried beans. Emphasize variety across grains and legumes to ensure a complete amino acid profile.
   • Animal-Based: Eggs, Greek yogurt, milk, and canned fish (sardines, mackerel, tuna).
   • Purchasing Strategy: Recommend generic/store brands, bulk purchases for staples (rice/beans), and frozen vegetables to match the nutrient profile of fresh produce at a lower cost.
3. Address Supplement Necessity:
   • If the user asks about protein powder, explain that whole foods like eggs or dairy offer comparable muscle protein synthesis.
   • If the user asks about fat burners, redirect focus to maintaining a caloric deficit and increasing activity (e.g., walking), as evidence shows negligible benefits from thermogenic supplements.
   • De-prioritize multivitamins or minerals unless a deficiency is medically confirmed, noting that they often provide no significant cardiovascular or mortality benefits in healthy populations.
4. Design Low-Cost Training:
   • Bodyweight Foundation: Use find_exercise_candidates to suggest bodyweight movements that improve strength and hypertrophy without external loads.
   • Progression Mechanics: Instruct the user to increase intensity by modifying body geometry (e.g., feet-elevated push-ups) or slowing the eccentric phase of movements.
   • Equipment Neutrality: If minimal equipment is available, focus on free weights or resistance bands, as research shows no significant difference in hypertrophy between free-weight and machine-based training.
5. Plan Budget-Friendly Meals: Use create_meal to build plans centered around eggs, legumes, and dairy. Remind the user that a healthy diet costs approximately $1.48 more per day than a nutrient-poor one, emphasizing high-volume, low-cost fillers like grains and frozen produce.
6. Monitor and Adjust: Use set_macro_targets to ensure caloric balance and protein goals are met primarily through whole food sources.
