weight = 180 pounds
time = 24 hours
formula: 1 calorie per hour for every kilograms of body weight
* add 200 calories per day.
180 lbs * 1kl/2.2 lbs = 81.82 kgs
1 cal/hr * 24 hrs * 81.82 kgs = 1963.68 calories
1963.68 + 200 = 2163.68 calories in total.
An author's credentials can determine a health source's credibility. None of the other options would apply to credibility. When it comes to health, if you want to make sure that what you are researching or reading is authentic and reliable you need to find out whether the author is a professional health expert or not. You can do this by finding out their credentials.
