Lawrence is an overweight male adult embarking on his first attempt at weight loss. He has heard that in order to lose one pound of fat per week, he should cut kilocalories by 500 kilocalories per day from his normal intake. What is the theory behind the notion that a 500-kilocalorie daily deficit promotes weight loss of one pound of fat per week?

3,500-calorie rule

Explanation:

The burning of fat provides about 9 kcal/g of fat and one pound of weight equals 454 g, therefore, one pound of fat contains 4086 kcal.

However, the research on the burning of fat indicates that about 3500 kcal are burned as the fat contains only 87% of the lipid which is burned and therefore 87% of 454 will provide 3,500 kcal.

So according to the 3,500 kcal rule, if one pound of fat has to be burned in one week therefore 3500/7 kcal has to burn daily.

Thus, 500 kcal according to the 3,500 kcal rule will be burned.

one characteristic that is shared by all is a soft body. many

of these invertebrate animals also have an outer shell to protect their

body. oysters, clams, snails, and mussels are all mollusks. so are octopuses, squids, and slugs. mollusks live on land and in freshwater.

one is through turgidity. this occurs before ground tissue ( collenchyma

and sclerenchyma cells) become well

developed to give structural support to the plant as it grows bigger. the xylem

tissue (composed of rigid tissue) of the young

plant render this support and also maintaining osmotic turgidity of the surrounding

plant cells.
