💧 Hydration
0 / 8 glasses
Aim for 8 glasses (64 oz) daily. Add a pinch of salt or electrolytes if you're training hard — plain water isn't always enough.

Why these numbers? (peer-reviewed sources)
BMR (branches by inputs). Default Mifflin-St Jeor (Mifflin et al., Am J Clin Nutr 1990; Frankenfield 2005). For trained users (≥3 sessions/wk), Ten-Haaf (PLoS One 2014). When body fat is provided, Katch-McArdle (uses LBM directly). Choice driven by O'Neill et al., Sports Med 2023 systematic review showing Mifflin under/over-estimates RMR in athletes.
TDEE. FAO/WHO/UNU 2004 PAL ranges (1.40–2.30), tuned by training frequency. Optional step-count input adds NEAT (~0.04 kcal/step/kg above a 7,000-step baseline). NEAT is the largest source of inter-person TDEE variance (Levine, Best Pract Res Clin Endocrinol Metab 2002).
Cut deficit, intensity-tiered. Conservative −12.5% · Moderate −17.5% · Aggressive −22.5%. Targets 0.5–1.0% of bodyweight loss per week; lean lifters should default to conservative. Garthe et al. IJSNEM 2011; Helms et al. J Int Soc Sports Nutr 2014; ISSN Position Stand on Diets and Body Composition (Aragon et al. 2017).
Bulk surplus, capped by experience. +7.5% / +12.5% / +17.5%; advanced lifters capped at +10%. Surpluses above +15–20% in trained subjects add fat without adding muscle (Iraki et al., Sports 2019; Ribeiro et al. 2019).
Protein (range, default highlighted). Cut: 2.3–3.1 g/kg LBM if BF known, else 2.0–2.6 g/kg BW (Helms et al. 2014). Bulk / advanced: 1.6–2.4 g/kg, default 2.0. Default reflects newer meta-analyses showing benefits past the older 1.6 g/kg breakpoint with no clear plateau through 2.2–2.4 g/kg in trained subjects (Tagawa et al., Nutr Rev 2020; Nunes et al., J Cachexia Sarcopenia Muscle 2022). Original ISSN/Morton baseline: Morton et al., Br J Sports Med 2018.
Fat. Floor 0.5 g/kg (hormonal health, esp. testosterone in men); 25% of calories as default target. Helms et al. 2014; ACSM 20–35% recommendation; Volek et al. on dietary fat & testosterone.
Carbs. Remainder after protein & fat. Performance floor: 3 g/kg/day for resistance training; 4–7 g/kg optimal for high-volume hypertrophy (Slater & Phillips, Sports Med 2011). Below floor, the calculator warns; below 100 g/day flags unintended keto territory.
Hard floors. Calories never below BMR for sustained periods. Absolute minimum 1500 kcal (M) / 1200 kcal (W) without clinical supervision.
14-day recalibration. Adaptive thermogenesis means TDEE drops 10–15% beyond predicted on cuts, rises on bulks (Müller & Bosy-Westphal, Obesity 2013). After 14 days the calculator compares actual vs predicted weight change and back-solves an effective-TDEE multiplier — this is what closes the gap between a generic calculator and one that feels custom.
Estimates based on the peer-reviewed sources above. Individual results vary with genetics, training history, sleep, stress, and adherence. This is not medical advice. Re-assess every 2–3 weeks against real-world progress (scale weight trend, training output, mirror).

Calorie burn estimates are approximations. Your actual burn depends on weight, intensity, and fitness level. These numbers are already factored into your training day macro targets — don't double-count them.
