Fats play essential roles in numerous bodily functions (one of the most important being hormone regulation). Don't eliminate macro nutrients for a "diet". Eat a well balanced diet and keep those healthy fats coming in.

What are examples of "healthy fats" and how much are necessary in a diet to loose weight. Ive been on Atkins for 2 years without exercise and lost 20 pounds but i still have a gut , I'm starting to run now and want to switch up my eating habits to a more balanced diet.

Bad: Saturated fat.
Good: Polyunsaturated fat
The best: Monounsaturated fat.
It's easy to cut trans fat out completely, almost impossible to completly cut out saturated, but you can keep it low.
Poly and Mono should be your biggest intake of fats. A lot of people supplement with EFA's (essential fatty acids) to get the full amount of the good stuff at each serving.
Cortisol does play a role in belly fat as well. May want to supp with an anti-cortisol.

Ignore any low-fat diet you hear about. If you want to change your diet to help reduce fat then remove a large amount of your carb intake. Carbs and calories are used for energy by your body but when you do not use up all the carbs/calories that you intake in a day then your body will store it as fat. Fats are very important when it comes to fat loss among other things. I would highly suggest supplementing with some form of Omega-3 fatty acids and keep it as a staple. Real mayo is a great source of monounsaturated fat/omega-3s and fish is obviously a great choice when it comes to dieting as it is high in protein and omega3 but is non existent in the carb area.

in reality sat fat is only bad if you are already overweight and/or have high cholesterol.
recently studies have found that dietary intake of cholesterol has no impact on the level of cholesterol in your blood.
cholesterol is also important for testosterone production as well as maintaining the integrity of muscle cell membranes.
so higher dietary cholesterol has been associated with greater gains in lean body mass.
and low testosterone can lead to less lean body mass and higher fat mass --> high cholesterol.

Yup, my bad. Talked to a buddy of mine today who has endless access to blood work. He was eating whole, hard boiled eggs (and other stuff) for bulking. At first, his cholesterol went up, but then came back down to normal and he is super fit. This is great, always learning.

Although coconut oil's fatty acids have some of what seems to be significant applications, it is still over 90% saturated fat. Saturated fats, no matter what other good things they do, will still raise your LDL levels, and therefor cholesterol. But, after all this fat and carb talk, whether you increase your body fat or decrease your body fat comes down to calories. If you burn an extra 3500 calories, you will lose a pound of fat. If you absorb an extra 3500 cals, you will gain a pound of fat. The different substances (carbs to fats ratio, good fats to bad fats, cortisol, leptin, pyy, I can go forever) that are discussed only can give you so much of an edge. Focus on calories. Eliminate 500 a day to lose 1 pound a week.

and saturated fat's role in cholesterol levels is now a debatable issue.
it seems evident that overweight people handle and process fat sources very differently than leaner folks.
for some people sat fats raise cholesterol levels, and for many others it has no effect.
most often it is those who are overweight and/or are prone to high cholesterol levels that fall into the first category.
although, it could very well be the fact that fatter people are typically consuming crappy sources of sat fats that are often times accompanied with trans-fat (the real culprit to issues like heart disease).
even though evidence is now starting to favor no link between negative health issues and cholesterol/sat fats, i feel that it's probably best to still error on the side of caution if you are overweight and have high cholesterol.
i'd like to hear your thoughts on the subject if you have different insight on the matter.

Certain fats got a bad rap because they were shown to promote atherosclerosis. Stearic acid has been shown to be neutral w.r.t. atherogenticity, and some studies on Coconut Oil lead to the same conclusion . (Sources : 12. Grundy, S.M. Influence of stearic acid on cholesterol metabolism relative to other long-chain fatty acids. American Journal of Clinical Nutrition 60 (6 Suppl):986S-990S; 1994.

I agree with hank about the other unwanted junk that comes with saturated fats like trans fats. Not all fats are created equal. There really is no definitive answer yet, but those predisposed to heart conditions/atherosclerosis and CVD are probably better off trying to lower their intake of cholesterol and saturated fats. Actually a plant-based diet is very intriguing, but that's another story (See the China Study if you're interested in that)

Saturated fats are chemically inert, meaning attacking oxidizing radicals can have no effect on them, due to their bonded structure. However trans fats are a different story. I believe that high levels of insulin in combination with a sedentary lifestyle are the major contributors to CV disease.

cut the microwave popcorn out, I just realized the other day how much saturated and trans fat it has!! lol

Trans fats are pretty resistant to oxidation, just like saturated, which is why they both make such great and are used for preservatives.Saturated fats are chemically inert, meaning attacking oxidizing radicals can have no effect on them, due to their bonded structure. However trans fats are a different story. I believe that high levels of insulin in combination with a sedentary lifestyle are the major contributors to CV disease.
The actual idea behind trans fat wasn't a bad one... chemists had originally hoped that by turning a cis isomer of a mono-unsaturated fatty acid into a trans isomer, they would have both the health benefits of mono unsaturated fats and the stability of a saturated fatty acid... too bad they created the Damien of fatty acids.
I definitely agree that the high insulin and sedentary lifestyle are the main cause of CVD. In my opinion, there is definitely a connection between eating sh***y carbs and high saturated fat foods with high LDL levels. There really doesn't seem to be the same kind of trend going on with healthy individuals who eat relatively clean diets, even if they are high in saturated fats.

then we are in agreement. And i know trans fats are also resistant to oxidation, but due to their structure it behaves differently in the body. But how to natural trans fats such as those found in coconut oil differ? that is something i do not know.
