180 cm, 80 kg
Worked TDEE result
A moderately active 25-year-old man at 175 cm and 75 kg has an estimated TDEE of 2,672 kcal/day. See his BMR, activity range, calorie goals, and macros.
Start with your TDEE-based maintenance estimate, choose a goal, and compare macro splits for the same calorie target.

Step 1: Choose your goal
Pick 1 of 5 calorie targets. Select a goal to preview its daily calories, weekly rate, and the 3 macro split options for that goal.
For a 25-year-old man who is 175 cm tall, weighs 75 kg, and is moderately active, the estimated TDEE is 2,672 kcal/day. In everyday terms, eating close to 2,672 calories per day would be a reasonable starting point for maintaining the same weight. It is an estimate, not a daily requirement that must be hit exactly.
Because this profile does not include body-fat percentage, the calculator uses the Mifflin–St Jeor formula. The complete calculation is BMR: 10 × 75 + 6.25 × 175 − 5 × 25 + 5 = 1,724; TDEE: 1,724 × 1.55 = 2,672 kcal/day. BMR is the estimated energy the body uses at rest; the activity multiplier turns it into an estimate for a full day.
Moderately active should describe the whole week, not only time spent in the gym. Walking, active work, household movement, and training all contribute. This profile would be about 2,370 kcal/day at light activity and 2,973 kcal/day at very active, so choosing the wrong row can shift the estimate by roughly 300 calories in either direction. The activity-level guide can help when two levels seem plausible.
The calculated BMI is 24.5, near the upper end of the general normal range. That alone is not a reason to lose weight. For this profile, maintaining steady habits may be more useful than chasing a lower BMI, especially if waist measurement, strength, fitness, and body composition are moving in a healthy direction.
The ideal-weight estimates of about 68.9–73.3 kg are height-based reference points. They do not account for muscle mass or build, so they should not override the broader picture.
Maintenance stays at 2,672 calories. A mild cut lowers the target to 2,172 kcal/day, while a lean bulk raises it to 2,922 kcal/day. Those are starting options rather than promises about weekly weight change. Someone already near a comfortable weight may benefit from choosing a goal based on training performance, waist trends, and personal preference instead of the scale alone.
At maintenance, the moderate-carb option provides about 201 g protein, 104 g fat, and 234 g carbohydrate. The other macro tabs redistribute the same calories, so the most useful choice is the one that fits food preferences and training.
Try the 2,672-calorie estimate consistently for two to three weeks and compare it with average body weight, not a single weigh-in. Then adjust in a small step if the trend does not match the goal. The muscle-gain guide explains how to use a surplus without rushing it. This example is educational and not individualized nutrition or medical advice.
