Sleep Restriction Results In Weight Gain Despite Decreases In Appetite And Consumption

According to a research abstract presented on June 8 at SLEEP 2009, the 23rd Annual Meeting of the Associated Professional Sleep Societies, in the presence of free access to food, sleep restricted subjects reported decrease in appetite, food cravings and food consumption; however, they gained weight over the course of the study. Thus, the finding suggests that energy intake exceeded energy expenditure during the sleep restriction

Results indicate that people whose sleep was restricted experienced an average weight gain of 1.31 kilograms over the 11 days of the study. Of the subjects with restricted sleep who reported a change in their appetite and food consumption, more than 70 percent said that it decreased by day 5 of the study. A group of well rested control subjects did not experience the weight gain.

According to lead investigator Siobhan Banks, PhD, a research fellow at the University of South Australia and former assistant research professor at the University of Pennsylvania School of Medicine, it was surprising that participants did not crave foods rich in carbohydrates after sleep restriction, as previous research suggested they might. Results indicate that even though physiologically the desire to eat was not increased by sleep loss in participants, other factors such as the sedentary environment of the laboratory and the ability to snack for longer due to reduction in time spent asleep might have influenced the weight gain.

“During real-world periods of sleep restriction (say during shift work), people should plan their calorie intake over the time they will be awake, eating small, healthy meals,” said Banks. “Additionally, healthy low fat/sugar snacks should be available so the temptation to eat comfort foods is reduced. Finally, keeping up regular exercise is just as important as what food you eat, so even though people may feel tried, exercising will help regulate energy intake balance.”

The study involved 92 healthy individuals (52 male) between the ages of 22 and 45 years who participated in laboratory controlled sleep restriction. Subjects underwent two nights of baseline sleep (10 hours in bed per night), five nights of sleep restriction and varying recovery for four nights. Nine well rested participants served as controls. Food consumption was ad libitum (subjects had three regular meals per day and access to healthy snacks, and during nights of sleep restriction subjects were given a small sandwich at one a.m.).

Restless Legs Syndrome: Causes and Treatments

by Patrick Boardman

Restless Legs Syndrome is a condition where limbs, usually the legs, have sensations of pain, itching, pins and needles, or other discomfort which produces an irresistible urge to move and which is temporarily relieved by flexing and moving the legs around. It usually occurs in the evening and isn’t as pronounced in the morning but is a cause of insomnia for the sufferer. RLS affects people of all ages but is more common after age forty. This article will deal with both primary RLS (meaning not caused by any other medical condition) and secondary RLS, as 60% of cases are familial (primary) and can be traced to an “autosomal” (meaning a non sex-determining) dominant chromosome. Secondary RLS usually occurs after the age of forty in people who are obese, who have had recent surgery, and those with osteoarthritis.

No prevention method has been established or studied but there are treatments available that alleviate the symptoms; one is a natural supplement branded as “All Calm”, a pure, refined, concentrated, and safe “magnesium citrate” in a special bio-available form that is prepared and consumed like tea so that it acts immediately. The manufacturer uses only USP grade ingredients and markets the preparation exclusively. It provides relief from both chronic Restless Leg Syndrome and bothersome leg cramps.

In 2005, the FDA approved the first drug for treatment of the disorder, ropinirole (Requip). In 2006, the FDA also approved pramipexole (Mirapex). In addition several drugs approved for other conditions have been found to be helpful in clinical studies. These medications fall into four major classes: dopaminergic agents, sleeping aids, anticonvulsants, and pain relievers.

Evidence suggests that your doctor should test you for iron deficiency and then supplement your diet with iron or vitamin B-12. It’s also necessary to look at other medications that may have RLS worse such as medicine for high blood pressure, heart conditions, nausea, colds, allergies, or depression. Herbal remedies, alcohol, and diet can be factors to be considered. No single pharmaceutical drug for RLS has proven to be entirely effective in eliminating the symptoms for everyone. The imbalance suggests that lifestyle, exercise, and diet are such major factors on the neurological communication with the muscles. Symptoms can be lessened with stretching, running, massage treatment, acupressure, yoga, tai chi, or simple walking. Having a good balance of nutrients with iron, potassium, and B vitamins is always a good idea. Bananas contain high levels of potassium and are effective at reducing cramps in the calves and thighs.

When sleep deprivation occurs it may be wise to eliminate caffeine as much as possible. Chocolate, coffee, tea, and soft drinks all contain high levels of caffeine and should be avoided to prevent sleep loss. Good sleep habits like regular hours rather than naps or oversleeping will help to keep the body’s energy ready to function rather than to sink into depression and fatigue.

Whether the treatment is pharmaceutical or natural it’s advisable to consult with your doctor since medicines or dietary substances can affect each other and may be dangerous. Various drugs have been used in the treatment of RLS: antidepressants such as Prozac, Elavil, and Lexapro; antihistamines found in cold, allergy, and over-the-counter sleeping pills; anti-nausea medications like Phenaergan, Reglan, and Compazine; even some psychiatric medications to treat bipolar disorders and schizophrenia. These substances can be dangerous and should be taken only on the advice of a doctor. With the success rate of the natural remedy All Calm, it is probably best to try the most natural substance available before using pills that have general toxic effects on other systems of the body. As with every remedy, be sure to follow the instructions carefully and use only after consulting a doctor if you have a medical condition.
