Question

Summarize forms of cell communication and/or signaling.

Answer 1

Cells use the release of a hormone to trigger a certain reaction when it is recieved. When fat is stored it gives of leptin and when the leptin is recieved by brain cells it tells you you are not that hungry anymore

Answer 2

@macmaz1 and that's why it's important to eat lots of fatty foods so you won't feel hungry?

Answer 3

actually because we eat on a scheduled we usually eat due to our 3 time appetite and not actual hunger. when you are in the wild and you eat only when hungry because there isnt enough food then the leptin will help you stay thin but when you ignore the lepton response and eat just because food is available and its lunch time of because there is a pizza at the meeting your brain will become leptin resistant and you will get fat. If you want to know anything else about exersize of dieting just ask. my father is the head of a research lab and is a member of the British royal College of Physitians.

Answer 4

Oh wow, hey @mazmaz1, so apparently the eating habits of humans.. why there are so many fat people harshly saying, is because it is expected, that how humans are. Do you think a human has to become self conscious about all that before weight loss is really possible, fat people just don't think about it..?

Answer 5

Yes and it becomes very hard for them because the more fat you have the more leptin is in your blood and then when they loose weight their body thinks they dont have enough fat because it is desensitized to leptin and thus need alot of leptin in the blood to keep them satiated. your body can however adapt so that your level of leptin needed to keep you from being hungry is lower. for example. my grand father is an active 79 year old who rides a motorcycle and is actually quite rich as he owns a bunch of factories. He is 5'7 and weight 110 lbs. when he visits us and we get pizza for lunch he cant eat dinner because he will just feel nausious about eating because of all the leptin the extra fat from the pizza in his body is producing. he served as an officer in the British army in Sudan (sudan was still a British colony then) when he was young and hot used to eating rareley and often just eats once or twice a day.
