Inital Weight Loss Can Predict Longer Term Weight Loss Success


girlscaleThere is a relationship between initial weight loss and later weight loss results. Findings from this study [1], show that weight loss in the first two months of treatment are strongly associated with weight loss following the first year of an intensive lifestyle intervention.

In all cases, failure to achieve a 1- or 2-month weight loss threshold considerably increased the probability of not achieving a clinically significant weight loss at Year 1. The study found that few people who lose less than 2% at month 1 and less than 3% by month 2 go on to attain significant weight loss at Year 1.

As a comparison, intensive lifestyle interventions yield an average weight loss of up to 10% at 1 year.

The current findings are in agreement with Nackers et al. [2], who reported that obese women losing at a rate of ≥1.49 lb/week (≥2.7% weight loss at 1 month) are 5.1 times more likely to achieve a ≥10% weight loss at 18 months compared to those losing weight more slowly, defined as <0.5 lb/week (approximately <1% weight loss at 1 month).

Understanding Free radicals, Antioxidants and the Aging Process


Aging is at least partly due to a process called oxidative stress.  Oxidative stress can simply be described as free radical attack on bodily tissues and organs. Free radicals attack DNA, proteins and fats. This prematurely ages organs and tissues. Prolonged attack can injure body tissues and cause heart disease, macular degeneration, diabetes, cancer and it prematurely ages organs and tissues.

Your body is made up of millions of tiny cells. Think of each cell like a miniature factory. Inside each factory, there are power production stations called mitochondria. It's inside the mitochondria where food and oxygen are turned into energy.
In the mitochondria oxygen can be converted into free radicals. Free radicals are molecules with an unpaired electron. A molecule that's missing an electron is a very "unhappy" molecule. So, they search for an extra electron. However, when it snatches an electron from a nearby molecule, that molecule in turn is left with an unpaired electron. Mitochondria are near the free radicals they just created. This means they're often the first victims.

This process continues until two free radicals meet and react, satisfying their lone electrons. While this provides a happy ending for the two lone electrons, their search has left a trail of destruction. Cell machinery has been wrecked beyond repair. Some molecules have been ripped apart. This imbalance is known as oxidative stress. Oxidative stress is behind many of the disease states associated with aging, including heart disease and cancer.

Antioxidants are molecules that can prevent the damage of the free radicals by giving electrons to the free radicals without turning into free radicals themselves. This stops the chain reaction. So, antioxidants can prevent or slow the oxidative damage to our body.

The antioxidant defenses of your body are usually sufficient to prevent significant tissue damage. However, an overproduction of free radicals or a drop in the level of the antioxidant defenses will lead to an imbalance between free radical generation and antioxidant protection. Science has long held that damage by free radicals is behind many of the disease states associated with aging, illness and disease.

One of the functions of an antioxidant is to "quench" these free radicals before they create too much damage. You can see antioxidants at work in your own kitchen. Slice an apple in half, and watch it turn brown. That's an example of oxidation. If, however, you dip the apple in orange juice, the rate at which the apple turns brown is slowed. That's because the vitamin C in the orange juice slows the rate of oxidative damage. The rusting of metal is also an example of oxidation.

Human beings don't rust or change color, of course, but they can still oxidize. It's just called something different: illness and disease. So, if oxidation makes humans ill or diseased then it makes sense that eating more foods with antioxidants and taking antioxidant vitamins will be beneficial. Increasing your intake of antioxidants in theory will help detoxify substances that cause you to oxidize.

Several long-term studies show that a high intake of certain foods high inantioxidants appear to protect against some of these diseasesby binding the free radicals before they can cause damage to the body and cause aging and disease. However, attempts to duplicate these findings with vitamin supplements haven't met with as much success. That's because healthy foods can contain nutrients that may be helpful as well. Foods are considered to be the best way of increasing antioxidant levels because they're thought to contain a wide assortment of antioxidant substances.

There is a growing variety of foods found to contain surprisingly high levels of these disease-fighting antioxidants. Cranberries, kiwi, mango, papaya, oranges, nectarines, tomatoes, blueberries, and blackberries rank high among fruits. Beans, artichokes, snow peas, sweet potatoes and Russet potatoes are tops among vegetables. Pecans, walnuts and hazelnuts rank highest in the nut category.

Vitamin C, E and beta-carotene are some of the important antioxidants that we can obtain from food.  Other antioxidants include flavonoids / polyphenols that are found in soy, red wine, grapes, pomegranate, cranberries and tea. Lycopene found in tomatoes pink grapefruit and watermelon. Lutein found in dark green veggies like spinach, broccoli, kale, red pepper and asparagus. And lignans that are in oatmeal, barley, rye, and flaxseed. The antioxidants selenium is found in Brazil nuts, whole grains, brewer’s yeast, oats, brown rice, chicken, eggs, dairy, onions, salmon, seafood, tuna, and wheat germ.Asparagus on plate
