It should be thirty minutes three times a week for it to be beneficial. But if you want to go with a stronger goal, it should be four to five times a week.
In some cases yes. Kids tend to learn faster than the average toddler.
Can not be determined
BMR is known as Basal Metabolic Rate which requires information about person's height, weight, age and gender to determine the number of calories burned by a person in a day.
But here only number of calories i.e. 1300 is given which is not enough to find out Alex's Total Energy Expenditure (TEE) as there is no detail about his height, weight and age is given.
Average BMR in the USA:
For Women it is 1493 calories.
For Men it is 1662 calories.
BMR is different from BMI (Body Mass Index) because to find out body mass index only the data related to height and weight is required.

True, an advocate does speak out in favor to what they believe in.. Hope this is satisfying :))
