Total Daily Energy Expenditure (TDEE)

It seems there is an error in the Total Daily Energy Expenditure (TDEE) you provided (48,268 kcal/day), as it is extraordinarily high for a 20-year-old male. A more typical TDEE for someone of your age, height, and weight is likely in the range of 2,500 to 3,500 kcal/day, depending on activity level. I will proceed with a more reasonable estimate for TDEE and provide recommendations based on typical values.

Assumed TDEE Calculation

For a 20-year-old male weighing approximately 65.77 kg and with a height of 5181.6 cm (which seems to be an error, as it is approximately 51.8 m), I will assume a more typical height of around 180 cm (5'11") for calculations.

Using the Mifflin-St Jeor Equation for estimating Basal Metabolic Rate (BMR):

• BMR = 10 weight(kg) + 6.25 height(cm) - 5 * age(y) + 5
• BMR = 10 65.77 + 6.25 180 - 5 * 20 + 5 = 1,602 kcal/day (approx.)

Assuming a moderate activity level (TDEE multiplier of 1.55):

• TDEE = BMR Activity Level = 1,602 1.55 ≈ 2,484 kcal/day
