What two things could you do to bring about an energy balance if your average Calorie intake per day is lower than your TDEE as described in question

The correct answer to this open question is the following.

Although you did not include the options for this question or other references, we can say the following.

The two things you could do to bring about an energy balance if your average calorie intake per day is lower than your TDEE is the following.

Your TDEE is the Total Daily Energy Expenditure. So this means that if your average calorie intake per day is lower than your TDEE, you are losing some weight and you need more calories to maintain your ideal weight.

So what you can do is to include more calories such as pasta, in your daily diet, and start doing some strength workouts in the gym so you could build muscle mass in your body.

The general recommendation is to have balanced nutrition, taking care of the daily intake of calories.
