New Research Finds The Best Strategy On How To Lose Weight

Most of us know that the best strategy on how to lose weight is to reduce our calorie intake. But actually reducing the amount of calories that we consume is easier said than done.

A new study from the Fred Hutchinson Cancer Research Center may help us with basic strategies on how to eat less and lose weight safely.

After studying 123 overweight to obese and sedentary women ranging in ages from 50 to 75, researchers find that
  • Women who keep journals on the type of foods, and the amount of food that they eat lose more weight than women who do not keep food journals
  • Women who do not skip meals lose more weight than women who do skip meals
  • And women who do not eat out for lunch often lose more weight than women who do frequently eat out for lunch.
Based on their findings, the researchers recommend that postmenopausal women maintain a food journal, eat out less often, especially for lunch, and eat at regular intervals to help lose weight successfully.

When keeping a food journal, the researchers also recommend that you
  • Be honest by recording everything that you eat
  • Be accurate by measuring portions and reading labels
  • Be complete in you recording by including how the food is prepared and whether any toppings or condiments are added to the food
  • And be consistent by always carrying your food journal with you and faithfully record what and when you eat
These are simple tools that you can use to help you lose weight successfully.

Suicide - Is A Parasite To Blame?

The big question - Are people with risk factors for suicidal behavior more likely to be infected with the parasite, or does the parasite's affect on the brain cause people to be suicidal?

The parasite in question is Toxoplasma gondii. It is spread through contact with cat feces or eating undercooked meat or unwashed vegetables. This bug resides in brain and muscle cells, and is linked to mental illness and behavioral changes.

A new study of 45,000 Denmark women indicates that those infected with T. gondii are at an increased risk of attempting suicide. The researchers stress that they can not say that the parasite cause the infected women to commit suicide, but there is a predictive association between the parasite infection and suicide attempts later in life. More research is needed to determine a possible connection between infection and suicide attempts.

One-third of the world's population is estimated to be infected with the parasite. We can become infected by
  • changing an infected cat's liter box
  • eating unwashed vegetables
  • eating undercooked or raw meat that is infested with the parasite cysts
  • drinking contaminated water
  • and by not properly washing knives used to cut raw meat
Pregnant women can pass the parasite directly to their fetus. That is why it is advisable that pregnant women avoid changing cat liter boxes.

To reduce your risks of infection, properly wash and cook vegetables and meats, and always wash your hands after handling liter boxes and raw meats.

New Research Determines Which Diet Is Most Effective On How To Maintain Weight Loss

New research shows you how to keep those unwanted pounds off for good after working so hard to lose it in the first place.

A frustrating fact for those trying to maintain a healthy weight is that only one in six overweight people can maintain their weight loss over a long period of time. Many feel that finding a method on how to maintain their weight loss can be as allusive as the proverbial pot of gold.

One of the reasons why people tend to regain their weight after losing excess pounds is that their bodies experience a reduction in metabolism. In other words, their bodies burn fewer calories. This reduction in their metabolism makes it difficult to maintain a healthy weight.

Researches at the Boston Children's Hospital have a solution to this problem after studying the effect on metabolism of three types of diets:
  1. A Low Fat Diet with 60% of daily calories from carbohydrates, 20% from fat and 20% from protein
  2. A Low Glycemic Index Diet with 40% of daily calories from carbohydrates, 40% from fat and 20% from protein and
  3. A Low Carbohydrate diet with 10% of daily calories from carbohydrates, 60% from fat and 30% from protein.
The results show that the low carbohydrate diet produces the best improvement in metabolism after losing 10 to 15% of body weight. However, the low carbohydrate diet also causes hormonal changes that can lead to insulin resistance and cardiovascular disease.

The low fat diet has the worse effect on metabolism of the three diets studied. Metabolism plummets with the low fat diet, which can make it difficult for weight loss patients to keep the excess pounds off.

The low glycemic index diet, on the other hand, produces similar improvements in metabolism as the low carb diet without the negative hormonal changes. Another plus for the low glycemic index diet is that it does not reduce or eliminate any food groups. This gives weight loss patients a larger variety of foods to choose for their meals, which may encourage them to remain on a healthy diet.

The combination of beneficial effects on metabolism, no negative changes in hormonal chemistry and no elimination of food groups may make the low glycemic index diet the best choice to keep the excess weight off over the long term.
