I think the answer is here (http://jn.nutrition.org/cgi/reprint/135/2/155.pdf):

In the present study, the addition of these tea catechins
to a bile-salt micellar solution containing the hydrolysis products
of triacylglycerols, fatty acids, and monooleoylglycerol did
not affect the total fatty acid content in the micelles. The
results show that the catechin preparations do not exclude
oleic acid and monooleoylglycerol from a bile-salt micellar
solution, suggesting that catechin preparations do not suppress
triacylglycerol absorption by inhibiting micellar solubility of
hydrolysis products of triacylglycerols.

In conclusion, our study suggests that both green tea catechins
and heat-treated tea catechins suppress postprandial
hypertriacylglycerolemia, a risk factor for the development of
coronary heart disease. Our results, together with previous
observations, such as cholesterol-lowering activity (27,28) and
prevention of LDL oxidation in vitro (13) and in human
studies (14,15), strongly suggest that the ingestion of tea
catechins may prevent coronary heart disease.

Green tea combined with CLA I believe I remember reading seems to be a good combo for abdominal fat. CLA itself is fat, so I don't know that I would worry too much.

okay so i think that means it doesn't affect it much?

hmm...taking fat with green tea? sounds strange, where did you hear this?

Why would it sound strange? CLA has been shown to aid muscle retention or addition during cuts. Green tea extract is mainly an antioxidant with minor thermogenic benefit.

Are you under the assumption that consuming dietary fat is not good for losing body fat? Because that is just not true.

John Berardi for one, though, recommends the CLA/Green Tea Extract combo. I have read a couple of studies, but I can't find them at the moment on pub med, but I did find this (http://findarticles.com/p/articles/mi_hb223/is_200503/ai_n15064113) mention of one of them.

oh okay. i didn't know what CLA was, you just said it was basically fat so that's why i asked.

It is a fat, just like fish oil is a fat.

How could green tea block fat from fish or flax seed oil (or simply 'oil' as you refer)?

Keep in mind that fish oil pills are not simply 'oil' when I am spending money on supplements instead of eating 1 lb of fish everyday. :lol:

There are other studies to agree with this one? Who is the author of the study? What are his qualifications?

I am very interested in this. . . perhaps I will check it out in the next few weeks on pubmed.

What do you think they do for you then?

Fish on it's own is preferable to taking fish oil supplements, but if for some reason you can't or don't want to eat fish, take the supplements.

Fish Versus Fish Oil Capsules (http://longevity.about.com/od/lifelongnutrition/a/fish_oil_supple.htm)

Can I Skip the Salmon Then?
Fish has other benefits beside providing your body with omega-3s. Fish are a great source of protein and other nutrients that were not studied in this research. However, if fish is unavailable, it is good to know that fish oil capsules are good for you, too.

Given the option of chicken breast + fish oil supplements, or salmon, it makes more sense to choose the salmon when it's convenient.

Guava - but what about the rumor that too much fish oil can produce unusual facial markings?? :eek:!

Some of people's fear involves too much fish giving them potentially higher levels of mercury/pcb intake whereas high quality supplements are distilled at a molecular level to remove these toxins.

But I do both, supplements (pills and oil), and real fish.

The mercury concern would be one reason to choose supplements (or flax products) sometimes instead of fish, but consumption of moderate amounts of a variety of fish daily has not been linked to harmful mercury levels, especially if you're avoiding the large fish like shark, tilefish, mackerel, swordfish, and limiting fresh albacore tuna to three times per week or less.

For green tea...What exactly falls under this? Any hot green tea bags I find in grocery stores? I need to get rid of a lot of ab fat and may want to try the Green Tea/CLA combo.

I also read a study that Oolong tea can have the same results. I don't know how different this is from green tea.

And if you're looking to change up your diet, try these spices too (http://ezinearticles.com/?Fat-Burning-Spices&id=385749) and eat a grapefruit (http://vashtijoseph.wordpress.com/2008/06/02/5-surprising-fat-burning-foods/) in the morning.

White tea actually has even more of the antioxidants than green tea (as it's less oxidized as I understand it).

Green tea+CLA might make some minor difference, but I would worry about the overall diet and exercise more than this.

I actually take a green tea extract supplement as I'm not much of a tea drinker and the supp is pretty cheap online.

What do you think they do for you then?

I do not buy into a lot of the marketing behind supplements. Whole food is much better than a liquid shake and a better way to spend your money, ESPECIALLY if you are living on a budget.

At one point back in the day, I found myself eating two cans of tuna a day. Sometimes I would have tilipia, whiting, or salmon. At least 1, many cases 2 servings of fish a day.

In that case, fish oil pills would probably = waste of $$

I no longer eat two cans of tuna a day, sometimes I eat it every other day (I try not to eat from the same meat source twice a day minus whey for days I workout).

In this second case, supplementing with fish oil pills might not be a bad idea.

The omega 3 found in fish oil has many benefits, I am sure they are listed in many other posts here.

Summary:
Good for the brain
Good for cardiovascular strength
Good for reducing muscle soreness (I noticed a huge decrease in mine following a few days of supplementation)


I personally do not buy the mercury argument, and even if there are long-term side effects from mercury the benefits of eating whole fish are far greater than the risks (ask the very healthy, non-heart problem having eskimos).

Of course, you CAN buy fish oil supplements that are high grade, which have all impurities removed!

I think it is a good idea to try many different teas. You do not want to just drink the same thing everyday. . .that is boring. Live life a little bit.

If you drink a ton of green tea everyday and have stomach/bathroom problems, by all means continue drinking green tea (a natural laxative) instead of oolong tea (which has similar benefits and is good for digestion). :tucool:

the reason why i asked the original question is because i've read in various places that recommended drinking lots of green tea if you're eating really oily food. it's supposed to block the fat from it, so if i have some potato chips or something i try to have green tea afterwards. then i read somewhere that it's not worth taking the fish/flaxseed oil with green tea because of this.

You are rationalizing eating potato chips with green tea?

I do the same thing, though my food of choice is not green tea.

I will definitely look into this, I want to know that I am not wasting my money on fish and flax.

I am pretty sure there are not much studies on the effects, unless someone has done a study or someone can infer from what it is exactly that green tea does in the body (other than increasing your metabolism and removing antioxidants).

I am sure Arizona GT has a biased study somewhere I can find. . . :lol:
