Trouble losing weight? This might be why!

By

Some people find it harder to lose weight than others, but why is this? A new study has identified a molecule in fat cells that could be to blame.

Researchers have uncovered one reason why some people may find it hard to lose weight.

Researchers found that the fat cells of people who are obese show higher expression of a molecule called lysyl oxidase (LOX).

LOX is associated with fibrosis, or “scarring,” of fat tissue, which, as previous research has shown, can hamper weight loss efforts.

Study co-author Dr. Katarina Kos, who works in the Diabetes and Obesity Research Group at the University of Exeter Medical School in the United Kingdom, and colleagues recently reported their findings in the journal Metabolism.

It is thought that around 1 in 3 adults in the United States are obese, which puts them at increased risk of type 2 diabetes, stroke, heart disease, and some forms of cancer.

A lack of exercise and a poor diet are the primary causes of obesity, so it’s no surprise that eating a healthful diet and increasing physical activity are the first strategies we try in an attempt to shed the pounds.

But these interventions can produce mixed results: some individuals see the pounds fall off, while others find it much more challenging. The new study may have uncovered one explanation for the latter.

What causes muscle soreness and stiffness?

By

Muscle stiffness is when the muscles feel tight and difficult to move, particularly after resting.

Muscles stiffness can also be accompanied by pain, cramping, and discomfort.

It is usually not a cause for concern and can be treated with home remedies and stretching.

In this article, we look at some causes of muscle stiffness, as well as home remedies and when to see a doctor.

Causes

There are a variety of things that can cause muscle stiffness, including:

Exercise

Alongside sprains and strains, exercise or physical stress may cause muscle stiffness.

A common cause of muscle stiffness is exercise or hard physical labor of some kind.

Often, stiffness can occur when someone starts a new exercise routine or program or has increased the intensity and duration of their routine.

When this happens, the muscles are required to work harder, and this causes microscopic damage to the muscle fibers, resulting in stiffness or soreness. This type of injury is sometimes referred to as delayed onset muscle soreness (DOMS).

Any movement can cause DOMS, but it is commonly caused by:

  • jogging or running downhill
  • using weights
  • doing squats
  • doing push-ups

Sprains and strains

The most common cause of muscle stiffness is a sprain or strain, which can affect both the muscles and ligaments.

Is lack of sleep to blame for repetitive negative thoughts?

By

Scientists working with adults who fixate on negative thoughts have noted a link between this distressing compulsion and poorer-quality sleep, as well as shorter sleep duration.

Worriers of the world, is your repetitive negative thinking caused by lack of sleep?

Repetitive negative thinking occurs when a person compulsively lingers on thoughts and stimuli that are distressing and unhelpful, which often leads to a decreased quality of life and the emergence of mental health problems, tied to depression and anxiety, in particular.

Prof. Meredith E. Coles and Jacob A. Nota, both of whom are from the State University of New York at Binghamton, conducted a study that focused on the link between repetitive thoughts of moderate and high intensity — also referred to as “worry” and “rumination,” respectively — and an individual’s nightly sleep duration and habits.

Their findings have been reported in the Journal of Behavior Therapy and Experimental Psychiatry.

Walk 4,000 steps every day to boost brain function !

By

Recent research led by the University of California, Los Angeles shows that taking a short walk each day can help to keep the brain healthy, supporting the overall resilience of cognitive functioning.

Could a walk in the park help to maintain cognitive health in old age?

As we grow older, memory problems can begin to set in. These could be a natural part of aging and a minor annoyance, but in some cases, the issues may indicate mild cognitive impairmentand could even develop into dementia.

Regardless of how mild or severe these memory problems may be, they are definitely distressing and can affect an individual’s quality of life.

New research from the Semel Institute for Neuroscience and Human Behavior at the University of California, Los Angeles suggests that there is a relatively easy way of keeping your brain in top shape as you grow older: take a moderately long walk every day.

This could boost your attention, the efficiency with which you process information, and other cognitive skills, say first study author Prabha Siddarth and colleagues.

How exercise can help you quit smoking!

By

Today is the first day of the New Year — the day you promised yourself you’d quit smoking. If you’re finding it hard, try working out! New research shows how exercising may reduce tobacco withdrawal symptoms.

New research shows how exercise can help you kick the habit once and for all.

We all know that smoking is bad for us, but quitting can be hard. Withdrawal symptomssuch as irritability, trouble sleeping, or even depression are commonly reported by people struggling with tobacco addiction.

In addition to specialized support services that might help you to deal with these symptoms, meditation and avoiding smoking triggers are also helpful methods.

Exercise is known to reduce nicotine withdrawal symptoms. Older studies have shown that even a short 10-minute bout of moderate exercise can have immediate effects of reducing tobacco cravings.

The exact mechanisms responsible for this effect remain largely unknown. But new research brings us closer to understanding these mechanisms, as it shows how various degrees of exercise intensity affect nicotine cravings in mice.

Dr. Alexis Bailey, senior lecturer in neuropharmacology at St George’s University of London in the United Kingdom, is the corresponding author of the study, and the findings were published in the British Journal of Pharmacology.
