Your Eight Hormones and Weight Loss

2. Endorphins

- An endogenous opioid from the pituitary gland that

blocks pain, decreases appetite, creates a feeling of

euphoria (the exercise high), and reduces tension and

anxiety.

Blood levels of endorphins increase up to five times

resting levels during longer duration (greater than

30 minutes) aerobic exercise at moderate to intense

levels and also during interval training.

Also, sequent several months of regular exercise, you

develop an increased sensitivity to endorphins (a

higher high from the same level of endorphins), and

endorphins that are produced tend to stay in your

blood for a longer period of time. This makes longer

duration exercise easier (you're feeling no pain)

and it causes your exercise high to last for a longer

period of time junior exercise.

3. Testosterone

- An important hormone in both males and females for

maintaining muscle tone/volume/strength, increasing

basal metabolic rate (metabolism), decreasing body

fat, and feeling self-confident. It's produced by the

ovaries in females and by the testes in males.

- Females have only speaking of one tenth the account of

testosterone that males do, but even at that level in

females it also plays a role in libido and intensity

of org*sms. Production of testosterone in females begins

to decline as a woman begins to crack menopause

and in males it begins to decline in his forties.

Blood levels of testosterone increase with exercise

in both males and females elementary as for 20 minutes

into an exercise session, and label levels may remain

elevated for one to three hours adapted to exercise.

4. Estrogen

- The most biologically intense estrogen, 17 beta

estradiol, increases fat cave from body fat stores so

that it can be used and fuel, increases crucial metabolic rate

(metabolism), elevates your mood, and increases libido.

This hormone is at much higher folk levels in females,

but the ovaries plunge into to produce less of it as a woman

begins to buy menopause.

The degree of 17 beta estradiol secreted by the ovaries

increases with exercise, and folks levels may remain

elevated for one to four hours aftermost exercise.

5. Thyroxine (T4)

- A hormone produced by the thyroid gland, Thyroxine

riases the metabolic rate ("metabolism") of

all cells in the body. This increase in "metabolism"

helps you to feel more energetic and also causes you

to expend more calories, and thus is important in

weight loss.

Blood levels of thyroxine increase by well-nigh 30%

during exercise and remain elevated for several

hours afterward - this period of time is increased

by an increase in intensity and/or duration of

exercise. Regular exercise also increase thyroxine

levels at rest.

6. Epinephrine

- A hormone produced primarily by the adrenal

medulla that increases the come of destruction the

heart pumps and directs vital spark flow to where it's

needed.

- Stimulates catastrophe of glycogen (stored

carbohydrate) in the operating muscles and liver to use

as fuel. It also stimulates the distillation of fat (in

stored fat and in in hand muscles) to use as fuel.

The shade of epinephrine released from the adrenal

medulla is proportional to the intensity and

duration of exercise.

7. Insulin

An important hormone in regulating (decreasing)

blood levels of glucose ("blood sugar") and in

directing glucose, fatty acids, and amino

acids into the cells. Insulin secretion by the

pancreas is increased in response to a rise in

blood sugar as is often the case in agreement with a meal.

Typically, the larger the meal, or the greater the

quantity of simple sugars consumed, the larger

the insulin response. This is of sorts reason

that it's good to eat small frequent meals and

to limit consumption of sugar and of processed

bread, pasta and rice. The whole grain (non-

processed) versions of those products are a

much healthier choice.

Blood levels of insulin enter to decrease circuitously 10

minutes into an aerobic exercise session and

continue to decrease through at hand 70 minutes of

exercise. Regular exercise also increases a cell's

sensitivity to insulin at rest, so that less is needed.

8. Glucagon

A hormone that is also secreted by the pancreas,

but it's job is to raise arterial blood levels of glucose

("blood sugar"). When derivation sugar levels get too

low, glucagon is secreted and causes stored

carbohydrate (glycogen) in the liver to be released

into the ilk stream to raise exquisite sugar to a

normal level. It also causes the division of fat

so that it can be used as fuel.

Glucagon typically begins to be secreted beyond

30 minutes of exercise when acute leukaemia glucose levels

may get to to decrease.

So, next time you're exercising, think surrounding all

the wonderful things that are happening to your

hormones. It might even make you want to do more

exercise!
