How many calories do you have to burn to lose 1 lb

To lose 1lb in a week, you would need to cut your calories, 500-1,000 per day, from your typical diet.

This calorie deficit diet is not good though. It can cause hair loss, a cold body at all times, fatigue, and constipation. It can also cause weakness and mental health disorders. Regular excersise and eating healthy is better for long-term weight loss that will stay.

the correct answer is 4) heat and pressure

metamorphic rocks arise from transformation of existing rocks types, in a process called metamorphism. during metamorphism the original rock(prolith) change into metamorphic rock by heating (150-200c) and pressure of more than 1000 bar. the original rock can be sedimentary, igneous, or existing metamorphic rock.
