if m is the mass of your body . You must make an assumption that your body can be assilmilated to water hence impossible to do
you have specific heat of water 4.186 J /°C
1 degree fahrenheit is 5/9 degree centigrade
So Q = mcdt = (5/9) *m (in grams!) *4.186 J

1 calorie is the amount of heat needed to increase the temp of 1 gram of substance by 1 degree C. 2.2lbs = 1 Kg. 1Kg = 1000gm. Find out how much you weigh in grams. Celsius and Fahrenheit do not have the same zero point and its going to depend on YOUR starting temupature also. probably 98.6F If you weighed 100lbs that is 4.54 * 10^4g. and that is how many calories you would need. to raise 1 degree C is also 1.8 degrees F. divid (4.54*10^4)/1.8
this is 25,222 calories
Keep in mind that the calories you eat are Calories. that means 1 Calorie = 1000 calories

All previous ansverers are right, but their estimation is to high. If you multiply their results on 0.8 it's will be more precise (becose our body only on 70% made from the water and thesis "human body made from water" don't correct generally)

well isnt a Calorie the amount of energy needed to raise 1L of water 1*C (1.8*F)?
and one Calorie is equivalent to 4184 kJ

Weigh yourself and assume you're just made of water.
