What is the criteria for plateau detection?

A plateau is identified when weight fluctuations remain under 0.5kg for more than two consecutive weeks despite consistent tracking.

How does it handle energy deficit tracking?

It calculates the gap between TDEE and actual intake plus exercise, then uses a 7700 kcal/kg standard to estimate weekly weight loss progress.

Which BMR formulas are supported by this skill?

The skill supports the Mifflin-St Jeor (recommended), Harris-Benedict (1919), and Katch-McArdle (lean mass-based) formulas for metabolic calculations.

Are there safety limits for the caloric advice provided?

Yes, the skill enforces safety boundaries, recommending a minimum of 1200 kcal/day for women and 1500 kcal/day for men, or at least 1.2x the calculated BMR.

分析と監視

Analyzes health data, calculates metabolic rates, and tracks energy deficits using professional fitness formulas.

The weightloss-analyzer skill enables Claude to act as a data-driven health assistant, processing body metrics like BMI, body fat percentage, and waist-to-hip ratios. It utilizes established scientific formulas such as Mifflin-St Jeor and Katch-McArdle to calculate Basal Metabolic Rate (BMR) and Total Daily Energy Expenditure (TDEE). This skill is ideal for users who need to manage weight loss phases, track calorie deficits, and identify plateaus using automated health logs. It provides structured Markdown reports while enforcing metabolic safety boundaries and healthy weight loss velocities.
