TDEE is the same formula for everyone, but the practical calorie picture for endomorph body types has its own context that generic calculators miss. This page gives you the Mifflin-St Jeor estimate, then explains in plain language how this situation shifts the read — what tends to be true for endomorph body types, where most online TDEE advice fails this group, and how to validate the number against your real-world weight trend.
TDEE is your daily calorie burn at your current weight and activity level. The Mifflin-St Jeor formula is reliable across populations and is the right starting point for endomorph body types. What changes is the interpretation: the foods you eat, your training context and the metabolic specifics of this situation all shape how the number plays out in practice.
Treat the calculator below as the first draft of your calorie target. The second draft comes from validating it against 2–3 weeks of consistent eating and weekly weight checks. For endomorph body types, that second draft matters more than usual.
Most TDEE calculators ignore the practical realities of endomorph body types: macro composition that affects satiety and the thermic effect of food, hormonal or recovery contexts that shift activity tolerance, and dietary patterns that make hitting the calorie target either easier or harder than the number suggests.
The math stays the same. The path to actually eating at that math — consistently, sustainably, without misery — is where endomorph body types needs a tuned approach instead of a one-size template.
For fat loss, a 300–500 kcal deficit below the TDEE you calculate here is the safe, evidence-backed starting zone for most people in endomorph body types. For maintenance or recomposition, eat at TDEE and let training drive change. For lean bulks, 200–400 kcal above TDEE keeps the fat:muscle ratio in your favour.
Beyond calories, the protein floor matters most: 1.6–2.2 g/kg bodyweight supports muscle retention in a deficit and growth in a surplus. For endomorph body types this is non-negotiable — under-protein eating is the fastest way to undermine any TDEE-based plan.
Inside AJYX, TDEE is recalibrated weekly from your actual intake versus your actual weight trend. For endomorph body types, that adaptive approach is more valuable than any single formula — it accounts for the contextual factors a calculator cannot see, simply by reading what your body is actually doing.
The app pairs this living TDEE with macro guardrails that respect your situation — protein floors, fat minimums, carb ranges that fit your training and dietary pattern. The result is a target that survives contact with real life.
Mifflin-St Jeor is the right starting point. For endomorph body types, the formula itself works; what matters is the activity factor you pick and the willingness to validate the number against 2–3 weeks of weight-trend data.
Pick the level that reflects an honest average training week, not the best one. Most people over-estimate by one notch — start at 'light' or 'moderate' and only move up if the weight trend confirms higher needs.
Eat 300–500 kcal below TDEE for fat loss, at TDEE for maintenance or recomposition, 200–400 kcal above for lean bulks. The right adjustment depends on your specific goal, not on endomorph body types alone.
2–3 weeks of consistent eating is the minimum window to read the trend. Weekly weigh-ins (same conditions) plus tape measurements or photos every 2–4 weeks tell you whether the number is right for you.
This page is tuned for endomorph body types, so we pre-fill the defaults we are confident about (sex or age range) to save you time. You can overwrite any field if it does not match your situation.
