The Science Of Low carb Diets Why They Work

You long for firmer muscles and smaller waist. Everybody does. Do you think you can’t lose weight? Yes, you can. But the truth is you can’t lose weight without a diet – a plan.

Low Carb Diet

Weight-loss experts and diet plan authors all agree that much of our excess weight comes from the carbohydrates we eat, especially the highly refined or processed ones such as potatoes, baked goods, bread, pasta and other convenient foods. To aggravate the problem, few of us get enough exercise to ward off excess pounds.

The basic science behind the low carb diet is to limit the consumption of foods with a lot of carbohydrates. The low carb diet includes many popular weight-loss programs such as the Atkins, South Beach, Zone and Carbohydrate Addict Diet.

Does It Really Work?

One of the food groups which the body needs to survive are carbohydrates. Carbohydrates also referred to as carbs come in two types – sugars and starches. Sugars are simple carbs usually sweet tasting like biscuits and sweets and easily digested. Whereas, starches are complex carbs found in bread, pasta, noodles and rice and take longer to digest.

The body transforms all these digestible carbs into glucose, the sugar that our cells use as fuel or energy. When glucose molecules pass from the intestine into the bloodstream, the pancreas releases insulin, a hormone that mobilises cells to absorb it. Muscle, fat and other cells then absorb the excess glucose from the blood and insulin levels return to normal.

After a meal high in glycemic index (ranking of foods according to how fast their sugars are released into the bloodstream), blood-sugar levels rise higher and rapidly. The insulin needed to fill all that sugar into muscles and fat cells also weaken the activity of glucagon, a hormone that signals the body to burn stored fuel when blood-sugar levels fall below a certain point. Glucose level drops so low leaving the body starved for energy. The brain and intestine then send out hunger signals. New cravings are created requiring more carb intake. We, then overeat that leads to more fat, rise in blood insulin level, more hunger, and more weight gain and the cycle goes on.

On the contrary, adhering to a low carb diet puts an end to this cycle. Reduced carbohydrates would mean decreased insulin level, increased glucagon level, weight loss, improved triglycerides (fats carried in the blood which are necessary but when excessive cause coronary damage), decrease in LDL (bad cholesterol), increase in HDL (good cholesterol).

The bottom line – Give refined or processed carbohydrates which cause rapid changes in blood sugar, trigger hunger, thereby encouraging overeating that ultimately leads to obesity smaller spots on your plate. Anyway, nobody ever died from skipping potatoes, pasta, rice and white bread.

That said; go get yourself a few good low carb cookbooks. Better still, leaf through this site’s 1,000+ low carb recipes – a seemingly endless variety of recipes. Try every recipe imaginable and make this diet as enjoyable and diverse as possible.

Yes, you can diet. Lose weight! Live longer!

Links Between Stress Shift Work And Serotonin Levels

The 21st Century is best characterized by the advent of ultra-modern technology, global commercial and business, and the unstoppable desire to get and stay ahead. Because of these factors, business corporations compete in a world where the economy is active 24 hours a day, seven days a week. This phenomenon created a demand for employees that would work even during the night upto the wee hours of the morning. This work schedule reversed employee lifestyle, making the day their time to for sleeping. Shifts may disrupt the normal body functions, hamper sleep cycles, and reduce the body’s serotonin levels. Serotonin is a neurotransmitter that is found in the central nervous system and impacts multiple functions like mood, sleep, sexuality, and appetite. This neurotransmitter may also promote cell regeneration.

Studies show that non-day shift workers tend to have lower levels of “feel-good” hormones called serotonin. Researchers at the University of Buenos Aires led by Dr. Carlos J, Pirola studied 683 men and compared 437 day workers to 246 shift workers. The results, the shift workers’ serotonin levels, measured through blood tests were significantly lower than those on regular day schedules. In addition to reduced serotonin levels, shift workers were also found to have higher cholesterol, hip-to-waist ratios, increased blood pressure, and higher triglyceride levels.

Because serotonin levels administer sleep patterns and other body functions, the University of Buenos Aires study suggested that shift work may also lead to a so-called Shift Work Sleep Disorder. People with this disorder tend to remain awake when they should be sleeping. These individuals can be very tired during waking hours. This disorder takes place because of a work schedule that takes place during the normal sleep period. Because of this, people who have difficulty getting sleep because their bodies are still programmed to be awake. The time of being asleep and being awake is different from what the body’s internal clock expects.

Other studies also found out that non-standard and night shift work may affect the cardiovascular and metabolic systems. These studies suggest that there is a possibility that shift work is directly responsible for high blood pressure and increased body fat, according the researchers of the Buenos Aires study. In addition to the disruption of sleep patterns, reduced levels of serotonin are also linked to other conditions like stress, anxiety, and depression.

Lifestyle changes can lead to improved serotonin levels. To make serotonin levels consistent, sleep patterns should be consistent and food regimens should include necessary vitamins and minerals to control the serotonin levels. Certain drugs and substances like caffeine, nicotine, alcohol, and antidepressants should be avoided because they may deplete serotonin production.

Individuals who want to improve their serotonin levels can use medication to aid them in their goal. The amino acid 5-HTP can be taken as a supplement and improve the body’s ability to manufacture serotonin. Another amino acid called L-tryptophan is used by the body to produce serotonin. However, before taking these supplements, patients are advised to seek the approval of doctors and other health professionals. Individuals who choose to work in the night should maintain adequate rest to lessen ill-effects that may develop. Healthy lifestyles and nutritious food regimens may improve serotonin levels and improve one’s quality of life.
