To put some numbers on this... there's 3500 calories in a pound. If we assume a person burns 2000 calories in a day then a 30 day fast is 60,000 calories or 17 pounds.
The average height of a man in the US is 5'10". The difference between the low end of normal BMI to high end of normal is 132-167, or 35lbs. So even a person at the high end of normal BMI could easily fast for 30 days without going underweight.
