What this TDEE result means

For a 40-year-old man who is 180 cm tall, weighs 90 kg, and selects sedentary activity, estimated TDEE is 2,196 kcal/day. That is the starting maintenance intake for a routine with little deliberate exercise and limited movement. If the week includes more walking, training, or physical work than that description suggests, actual maintenance may be higher.

The calculation behind 2,196 calories

Without a body-fat entry, the calculator uses Mifflin–St Jeor. The compact calculation is BMR: 10 × 90 + 6.25 × 180 − 5 × 40 + 5 = 1,830; TDEE: 1,830 × 1.2 = 2,196 kcal/day. BMR estimates energy use at rest. The sedentary multiplier adds a modest allowance for ordinary daily movement and digestion.

Sedentary is the key assumption

Moving just one row up to light activity increases this profile’s estimate to 2,516 kcal/day. Moderate activity reaches 2,837 kcal/day. That does not mean a workout should be added on top of 2,196 automatically; the multiplier is meant to represent the complete routine. A desk-based week with little walking may fit sedentary, while regular steps and training may justify a higher level.

Interpreting a BMI of 27.8

The calculated BMI is 27.8, within the general overweight range. BMI is a screening measure, not a diagnosis, and it cannot distinguish muscle from fat. If reducing body fat supports this person’s health goals, a useful first step would be a modest calorie deficit paired with attention to waist, weight trend, energy, and strength—not an automatic push toward the lowest possible weight.

The height-based ideal-weight estimates span roughly 72.6–78.8 kg. They omit frame size, muscle mass, health history, and current body composition, so they are broad references rather than a deadline or prescription.

Why the largest cut may be too much

Maintenance is 2,196 calories, while the mild cut is 1,696 kcal/day. The aggressive cut drops to 1,446 kcal/day and triggers the calculator’s low-calorie warning for men. A smaller reduction may better support hunger control, training, and long-term adherence. The sustainable deficit guide explains how to choose a more manageable pace.

Use macros after calories

At maintenance, moderate-carb provides about 165 g protein, 85 g fat, and 192 g carbohydrate. Other macro splits keep total calories constant, so preference and consistency matter more than finding a perfect ratio.

Treat 2,196 as a baseline to test for two to three weeks. Compare consistent intake with average weight rather than reacting to daily fluctuations, then adjust gradually. Health-related weight decisions are best discussed with a qualified clinician; this example is educational only.
