You might be on to something with the Omega 5 oil and CLA... see:

Efficacy of conjugated linoleic acid for reducing fat mass: a meta-analysis in humans1,2

Leah D Whigham, Abigail C Watras and Dale A Schoeller
1 From the Department of Obstetrics and Gynecology, University of Wisconsin School of Medicine and Public Health, Madison, WI (LDW), and the Department of Nutritional Sciences, University of Wisconsin-Madison, Madison, WI (ACW and DAS)


Background:Conjugated linoleic acid (CLA) has been shown to be an effective supplement for reducing fat mass in animals, whereas results in humans have been inconsistent.

Objective:This is a meta-analysis of human studies in which CLA was provided as a dietary supplement to test its efficacy in reducing fat mass.

Design:We searched the PubMed database (National Library of Medicine, Bethesda, MD) and references from the resulting search to identify studies in which CLA was provided to humans in randomized, double-blinded, placebo-controlled trials and in which body composition was assessed by using a validated technique.

Results:We identified 18 eligible studies. Of these, 3 were single-isomer studies, and results comparing CLA isomers were inconclusive. We compared the length of treatment by using studies in which a mixture of purified isomers were used and those in which purified trans-10,cis-12 isomers were used. This comparison indicated that the effect of CLA was linear for up to 6 mo and then slowly approached an asymptote at 2 y. An analysis of the dose effect indicated that fat loss compared with placebo was –0.024 kg · g CLA–1 · wk–1 (P = 0.03). After adjustment to the median dose of 3.2 g CLA/d, CLA was effective and produced a reduction in fat mass for the CLA group alone (0.05 ± 0.05 kg/wk; P < 0.001) and for the CLA group compared with placebo (0.09 ± 0.08 kg/wk; P < 0.001)

Conclusion:Given at a dose of 3.2 g/d, CLA produces a modest loss in body fat in humans.

Vitamins are the stars of the nutrition scene. Nutrition,the science of food, is the study of the nutrients andsubstances in foods. Scientists examine how the balancesof food compounds relate to health and disease, and explorehow they interact during the process of ingestion,absorption, utilization, and excretion.

There are six essential nutrients for health and bodymaintenance: vitamins, minerals, water, fats, proteins, andcarbohydrates. They are the building blocks of life, and weobtain them through our diet. Our bodies don’t make them.

At this time, it is known that there are fourteen vitaminsrequired by humans. Vitamins, first discovered in thelate 1800s, are organic compounds found in foods. Sincethey are organic - containing carbon - they can bedestroyed by heat, unlike their companion essentialnutrient group, the incombustible minerals.

In the early 1900s, when scientists were continuing todiscover new vitamins, they named newly found compounds byalphabet: A, B, C, D, E~. K. Note: The compounds that hadbeen named F, G, H, I, J were later disqualified asvitamins, not fitting the definition: organic compoundsneeded in small quantities for life growth and maintenance.Compounds that have been given letters with numbers, B-1, B-2~ were originally thought to be one compound, but laterdetermined to be several different compounds with specificfunctions for each.

Vitamins are in one of two classes: fat soluble or watersoluble. Vitamin C and the B vitamins (such as niacin andriboflavin) are water soluble. Vitamins A, D, E, and K arefat soluble. Which type of solubility each vitamin haswill indicate which foods contain them. Basically, non-fatfood has no fat soluble vitamins. However, highly coloredvegetables like carrots do contain beta-carotene - a proto-vitamin which can be converted to active vitamin A.

Water soluble vitamins are easily shed by the body andlost from foods during preparation. Since they aren’tstored by the body, we need to ingest them every day.Nevertheless it is best to avoid taking them excessively.On the other hand, fat soluble vitamins are readily storedby the body. Thus caution is necessary to avoid excessivequantities; it is possible to build up toxic levels of thefat soluble vitamins.

People commonly wonder if they need to take vitaminsupplements, and which vitamins should be taken for goodhealth. The situation today is that our foods are comingto us from conditions that previously were never the casefor humans. Modern food is highly processed, and isfrequently grown in depleted soils. Our foods are pickedunripe and therefore incomplete from the standpoint ofnutrition. Then they are shipped and handled more than theideal. Therefore, it seems unlikely that the averageperson’s diet provides sufficient amounts of necessarynutrients - vitamins and minerals in particular. Instead,we are consuming excessive amounts of harmful compoundslike preservatives and refined sugars.

A suggestion. Do your own research project. Keep trackof what you eat for a week or two. Eat normally, and justwrite down what you ate and how much of it. Then eitherbuy or check out from your library a book on vitamins thatwill tell you approximately what you got from each foodsource. Add it up and compare to the recommended dailyallowances. See how you’re doing, and if you think it’s agood idea to make some improvements, consult with aprofessional nutritionist, naturopathic physician, or otherhealthcare professional to come up with a good plan of dietand nutritional supplements. You’ll see what a profounddifference good nutrition can make in your health.

Researchers have given women another reason to shed that excess flab. Researchers have said that extra fat can damage eggs in the ovaries.

The study was conducted by a team of researchers from the University of Adelaide led by PhD researcher Cadence Minge and was conducted on pregnant mice.
While conducting their study the researchers noted that a fatty diet stops eggs from developing into healthy embryos, thereby affecting fertility.

“As a result, when fertilised, these eggs are not able to undergo normal, healthy development into embryos,” said Dr Minge.

“We hope our findings will encourage women to consider carefully the impact of their lifestyle choices on their own future and that of their children,” she added.

However, the researchers also found a way to completely reverse the effects, thus enabling the eggs to develop into healthy embryos. This was done by using the diabetes drug Avandia.

Using the drug the boffins selectively targeted a protein called peroxisome proliferator-activated receptor gamma (PPARg) and found they could undo the damage caused.

“The drug enables us to switch on the protein, thereby changing the way in which the ovaries sense and respond to fats,” Minge said.

“Embryo development rates are restored, and the cellular differentiation of the early embryo is improved,” she added.

However, Dr Minge also warned women that Avandia is not a safe treatment option for obese, infertile women at this stage.

“Also, the drug itself can have possible harmful side-effects, and more research is needed to find other, safer ways of activating the protein,” she said.

About Appetite Suppressors How Can They Help Reduce Weight
Appetite suppressors can be a help during a slimming process. On the market of today you can find both appetite suppressors related to the substance amphetamine and appetite reducers of herbal origin. Appetite suppressors are generally recommended to use together with a diet program and exercise, and only for a limited time period. They are never recommended to use as the only means of achieving a reduced weight.

Substances to reduce appetite have been used since the First World War. Soldiers used the stimulating substance amphetamine both to stimulate their fighting capacity and to reduce hunger. The same was done in the Second World War. After the last war, the civil market began to use amphetamine and related substances to help reduce the intake of food during weight loss efforts.

A. APPETITE SUPPRESSORS OF THE AMPHETAMINE GROUP

Amphetamine and related substances stimulate the alertness of the central nervous system and the impulse to external action. When zones of the brain dealing with external action are in high activity, signals are sent to zones controlling appetite, digestion and connected functions to reduce their activity. Thus central stimulating substances also reduce appetite. Since these drugs increase the bodily activity, they also help to reduce weight by inducing a higher rate of fat burning.

Some drugs of this group are also used as antidepressant, for example fluoxetine hudrochloride (Prozac).

Being central stimulants all these appetite suppressors also bear a certain risk of developing addiction, and of side effects like insomnia, agitation, manic reactions, hypertension, stroke, heart valve damage and heart rhythm disturbances.

Because of such dangerous effects, many of these substances have been banned from most markets as appetite suppressants, for example amphetamine itself, aminorex, fenfluramine, phenylpropanolamine and ephedrine. However, many of these substances are still used for other purposes, for example to stimulate heart activity and to regulate up a too low blood pressure.

Substances of this group available on the market today as appetite suppresants are: Phentermine, diethylpropion, phenidmetrazine, benzphetamine, sibutramine, rimonabant, oxyntomodulin and fluoxetine hydrochloride (Prozac).

PHENTERMINE

Phentermine is perhaps the most widely used appetite suppressant drug today. It works by increasing the release of the hormones / neurotransmitters norepinephrine, serotonine and dopamine, The signals from these substances make the nervous system more alert for external action and reduce appetite.

EPHEDRA AND EPHEDRINE

Ephedrine is a central stimulant extracted from species of the plant genus Ephedra. The substance is banned in most communities as a appetite suppressor nowadays, but are used for other medical purposes, for example to stimulate heart activity and increase blood pressure. In some communities Ephedra as a herb is still used as a part of stimulating herbal preparations.

SIBUTRAMINE

Sibutramine works by reducing the reuptake of the hormones / neurotransmitters serotonin, norepinefrine and dopamine and thus increases the effects from these substances, with increased alertness and reduced appetite as a result.

RIMONABANT

This is a new drug working by blocking signals receptors that increase appetite upon signals from neurotransmitters / hormones. These are the same receptors that react upon contact with substances in the narcotic herb Cannabis. The main action of this drug is appetite reduction. In addition to appetite reduction it also seems to help smoking cessation for certain smokers. Severe depression may be a side effect of this drug.

B. MODERN HERBAL APPETITE SUPPRESSORS

Because of the potential side effects of appetite suppressors from the amphetamine group, people often turn to herbal appetite reducers with a very long history of use in their country of origin without having shown the same side effects. The herbal appetite suppressors Hoodia Gordonii and pinnothine are two such herbal appetite suppressors of increasing popularity. Preparations containing these herbs generally also contain herbs that increase the burning of fat, or herbs that reduce the uptake of fat or sugar from the intestines.

HOODIA GORDONII

This is a cactus-like plant native in the African dessert Kalahari. The San tribe living in this region has used the herb in centuries to suppress hungers during long hunting expeditions. In the long traditional use, the herb has shown to suppress hunger without side effects.

The plant contains substances whose molecules resemble glucose molecules. When there is enough glucose in the blood, the brain interprets it as a signal to reduce the hunger. The substances of the Hoodia Gordonii give the same signal to the brain, and thus reduce the appetite.

PINNOTHINE

This chemical complex is found on the Korean Pine Nut tree Pinus Koreanensis, and the working substance of Pinnothine is pinnoleic acid, an unsaturated fatty acid with 18 carbon atoms, three double bounds and with the first bound on the fifth carbon atom (omega-5 poly-unsaturated fatty acid). Pinnoleic acid reduces the appetite by inducing production of a larger amount of the appetite regulating signal substance cholecystokinin (CCK), which then is released into the blood circulation. CCK in the blood is interpreted by the brain as a command to reduce the feeling of hunger. Another ways CCK works, is by delaying the emptying of the stomach content into the intestines, and by giving signal to the gall bladder to empty its content with digestive enzymes into the small intestine. The stomach will therefore lack room for new food a longer time each day, and this reduces the urge to eat.
