Why high dietary fat %? Are we trying to kill each other?

There have been some posts recently which suggest setting fat as high as 70% of total calories. Why would someone eating at a deficit consume so much fat? The food volume is low, the overall diet lacks fiber and micronutrients due to the low carbs, and the protein is too low to protect muscle mass.

And while I'm asking questions that are sure to get me flamed, where did the often referred http://www.myfitnesspal.com/topics/show/819055-setting-your-calorie-and-macro-targets originate? The idea of telling people who are obese to set their goals to "0.35g of fat per lb of total body weight as a minimum target" is poor science and could be harmful to their health. A 250 lb person eating 1700 cals per day would be consuming 45% of their calories in fat. Why are we perpetuating this?


Notes: 1) Yes, I know that carbs do not contain micronutrients but carb containing foods do. 2) A 250lb female my age and height, sedentary, would be consuming 1700 cals at TDEE -20%

    It depends on what your goals are. I eat 50% of my cals from dietary fat (nuts, oils, fatty fish, and avocados). Avocados have tons of fiber. Not sure what the problem is...seems to be working pretty well for me. Feel free to check out my diary.

    Consuming dietary fat does not add to bodily fat. Dietary fat helps the feeling of "fullness" just like carbs do, but carbs metabolize very differently than fat.

    The recommendation would be made for someone on a low carb high fat diet. You can't eat potato chips and losing weight, but you can eat bacon and lose weight :)

    I think the 0.35 g per pound bodyweight is an estimate for optiumum vitamin solubility. Obviously heavier people will need more fat by that assumption, and I think the answer in the end is that it's different for everyone. Some people like high fat diets because it's known to me more satiating, I think it's really what works for you and your body.

    eating that quantity of fat is likely to give too much unhealthy fat, that's asking for artery clogging

    It's not all about losing weight. We should be aiming for sustainable good health. Eating excessive fat at the cost of other nutrients negatively affects long-term health.

    And yes, you can lose weight eating potato chips. As long as you stay at a caloric deficit.

    Because being extreme is the fad du jour. Blame the paleo/ primal folks for turning the overeating of bacon into a dieter's birthright.

    Nope, blame that on the abuse of Atkins from last decade's fad diet.

    dietary fat has no impact on body fat unless you're eating at a caloric surplus. fat is also great for long term energy whereas carbs are better for short term energy. I like long term energy. :)

    55% fat, 25% carbs 20% protein

    Most hardcore Atkin's people I knew are dead.

    P/Ps kick it up to a notch that would have made Atkin proud.

    Oh no no no. People following the Paleo diet should be limiting their processed meat intake. Including bacon. I don't know a single Paleo/Primal person who will tell you that you can eat unlimited processed meats. (and I'm not including internet people, only those who are Paleo/Primal that I actually know in person.)

    what do you think the Paleo/Primal folk have wrong, out of curiosity? not that I agree with absolutely everything Mark Sisson says, but what's your beef?

    no you just said unprocessed foods don't contain unhealthy fat then concurred to eating bacon (a processed food) which will have unhealthy fats

    to add i don't care that it's processed and enjoy 300g of it every week, but if you want to talk as if you're going to eat a 70% fat diet without unprocessed foods and unhealthy fats clogging your arteries.... i disagree

    55% fat, 25% carbs 20% protein

    You are trying to gain weight - not lose. And you consume a ridiculously high calorie level that would require more fat due to density. I specifically said this is bad advice for those who are eating at a deficit and trying to support good health.

    Would you suggest to your "clients" that they consume more fat and less protein and carbs than their body needs? Because that's what's happening here every day.

    'cuz fat doesn't make you fat. Anyone doing low carb/no carb is going to have a diet high in fat as well as protein...if you eliminate one macro, the other's go up. It's all very simple really. So long as you are within your calorie goal it doesn't really matter. I get about 30% of my calories from fat...most of it from nuts, avocados, nut butters, olive oil, etc. I'm doing a 40/30/30 ratio of macro nutrients...if I was low carbing it, no doubt my fat macro would be at least 50%.

    Let's get out of the '80s shall we...it is 2013...fat doesn't make you fat.

    it's got nothing to do with making you fat, it's about internal health, over doing one thing to the other will cause problems, 30% fat is perfectly fine, 70% is not

    Dietary fat does not make you fat - overeating makes you fat.

    If you have a risk factor for clogged arteries, I guess I would touch base with your doc before eating a lot of dietary fat (even though I am not sure that is a direct cause of that either...but I am no doctor). I have no such risk and I eat 35% fat, 35% carbs, and 30% protein. My cholesterol/triglycerides have dropped into the normal range, my blood pressure is normal, etc. etc. etc...

    that's a great point, and one worth addressing

    if you're eating at a deficit, it's MORE important to hit your micronutrient levels than it is to hit any particular fat macro. Absolutely. That's why using percentages is silly on the whole. Protein requirements are essentially static, and only change with your lean body mass. I personally feel that you can't reach your micro nutrient goals very well unless you're hitting at least 100g of carbs through mainly fruits and veggies (that's an opinion, I know there are a lot of Keto fans out there - I'm not one of them).

    but once you know how much protein you need, and how many carbs your body feels good on and needs to hit nutrient levels, the rest can absolutely be taken up by fat if you so desire. It will NOT cause you any harm, as long as you avoid trans fats and stick to as many good fats as possible (coconut, avocado, olive, animal fats, etc)

    so even in a deficit, you can have a "high fat" diet and see incredible results, and do so in a healthy way.

    The problem wit Adkins was people take it to an extreme and do NO carb diets and thus are missing out on huge chunks of micronutrients the body needs to function.

    I eat 30% carbs, 30% prtoein, and 40% fat. I started at 245lbs, currently am 214, am a female, and I'm losing eating 1900 calories a day. I don't always hit my macros, but I try to get enough protein, and the rest kind of fall where they may. Like others, most of my fats are from lean proteins, nut butters, avocados, and olive oil.

    So, I essentially am the example you gave. How am I killing myself or anyone else? Or was I supposed to be gaining weight?

    I routinely eat over 80 grams of fat per day, and my blood work is superb. I have been a vegetarian since birth, and have always had a very high fat diet without any problems (until a recent sports injury caused me to gain weight). I get all of my fats from nuts, seeds, avacados, healthy oils. I would never tell someone eating the standard american diet to try for 80 grams of fat per day, because I'm pretty sure they wouldn't do it by loading up on chia seeds and raw almonds.

    Actually you are consuming 30-35% from fat, except for the days you eat fries and chips. And even still, 40% is still a far cry from 70%.

    @TimeForMe99

    I want to clarify that I'm not sure 70% fat is a good idea either, because it's extremely unlikely you're meeting your micronutrient requirements.

    Where is your basis for asserting that the information in our thread is dangerous?
    Additionally, obese people may use lbm instead of total bodyweight but even still, considering that .35/lb is the minimum recommended value I don't see anything in that thread as being potentially dangerous.

    Why is .35g per pound considered the minumum valiue? According to whom?
