there is not a minimal recommended amount of unsaturated fatty acids based on body weight. the institute of medicine (iom) does provide adequate intakes for the two essential polyunsaturated fatty acids for males 19-70 year old: linoleic acid (la) -- 17g per day for males alpha-linolenic acid (ala) -- 1. 6g per day. these fats are essential because they cannot be made by the body. lower levels would still prevent essential fatty acid deficiency but it is difficult to say how low you could go. the question is why would you want to lower your fat intake to such a low level? the iom recommends a range of total fat between 20-35% of calories. some very low calorie diets (vlcd) may go below that but that should not occur without a doctor's supervision. for more on vlcd see this article. it's important to remember that you need fat to absorb fat soluble vitamins for satiety and satisfaction and to obtain other important fats such as dha and epa (from marine sources) which are vital for heart and brain health. good luck!
is there absolute minimal daily intake of unsaturated fat in grams or grams per body weight? grams not percents. im young adult male on strict balanced low calorie diet and i wonder whats the minimal daily intake of unsaturated fat in grams or grams per body weight and not percents. the only info i found was that with vlcd some researchers speculated that 15 to 25g of fat will decrease the chance to develop gallstones but on the other hand famous vlcds sold on the market contain less then 10g of total fat a day (one contains 6. 9g another 4. 7g and another 8. 4g) and theyre popular and considered safe.
