Recommended fat boundary -

This graph shows blood fat measurements from 1, participants who took part in our PREDICT 1 study. These measurements were taken at regular intervals over 6 hours after participants at identical breakfast at 0h and lunch at 4h meals.

The red line represents the mean response, blue indicates the median response, and each of the black lines represent an individual's blood fat response. As you can see, our research shows that everyone has a different response to the fats in our food. This also means that each of us has a different fat threshold.

To find your own fat threshold, you need to understand how your body responds to the fat in your food and how quickly you remove triglycerides out of your bloodstream. Our ZOE test kit contains the same standardized muffins as we used in our PREDICT studies , with specific amounts of fat.

After eating these muffins, we ask you to use a finger prick blood test 6 hours later to collect a blood sample. We use these blood samples to measure your blood fat responses and how well your body processes fats after you eat.

This gives us an idea of how you process fat and helps us find your fat threshold. For each food, meal, and day, the app gives you a score for the food you eat.

One part of the score includes whether you are likely to be hitting your personal fat threshold depending on the food you have eaten, the quality of the fat sources in your meal, and your unique metabolism. If you go above your fat threshold, you will notice that your scores drop.

Join our newsletter. No spam. Just science. Thanks for subscribing! How much dietary fat do we really need? This is one of the most common questions that stumps even the most seasoned and experienced fitness pros from time to time.

Are we trying to identify the minimum fat intake that prevents death? The minimum fat intake that prevents clinically relevant adverse effects? The minimum fat intake that is practically feasible? The minimum fat intake to support feeling good? The minimum fat intake that is compatible with optimal physical function?

The answer to each question will be a bit different. So, for this article, I want to focus on some of the key outcomes that establish informative boundaries for daily fat intake targets. I also want to make something very clear on the front end: this article exclusively pertains to healthy adults with no underlying medical conditions, and it does not constitute medical advice.

The gallbladder is a small organ located in the upper-right quadrant of the abdomen. Its primary function is to store bile, which is produced by the liver. When we eat a fatty meal, the gallbladder releases bile to facilitate the digestion of fat.

Gallstones are small, hard, pebble-like objects that form when bile hardens within the gallbladder. In many cases, gallstones do not cause any noticeable symptoms.

However, if they block a bile duct, they can cause a painful buildup of bile, and may eventually necessitate surgical removal of the gallbladder. Rapid weight loss programs can sometimes cause the liver to release extra cholesterol into bile, which can increase the risk of gallstone formation.

Beyond the risk associated with very rapid fat loss, extreme fat restriction seems to independently increase the risk of gallstone formation. In clinical weight loss trials in participants with obesity, you might be shocked to see exactly how extreme some of the intervention diets are.

Unsurprisingly, these types of diets have been shown on many occasions to increase the risk of gallstone formation. Fortunately, it seems that this risk can be dramatically reduced by adding some fat to the weight loss diet, and the necessary amount of fat is shockingly low.

Another factor impacting dietary fat needs is our unavoidable need for essential fatty acids. Different fatty acids have different physiological roles in the body, and the structure of a fatty acid dictates its function.

Fatty acids consist of a carboxylic acid attached to a hydrocarbon chain, and this hydrocarbon chain can vary in length. Conversely, omega-6 fatty acids have their first double bond located at the 6th position from the omega end Figure 2.

Finally, we can distinguish some unsaturated fatty acids from others based on the spatial orientation of their hydrocarbon chain.

Unsaturated fatty acids have at least one double bond that joins two carbons together, with a hydrogen atom bonded to each carbon.

Generally speaking, human beings are pretty good at rearranging the building blocks of fatty acids, rendering them largely interchangeable. We have all the enzymatic machinery necessary to chop up long fatty acid chains into shorter ones, build upon shorter ones to make longer ones, and swap between saturated and unsaturated bonds.

We lack the necessary enzymes to place a double bond at the 3rd and 6th position of these long-chain fatty acids, but sufficient omega-3 and omega-6 availability is considered essential for optimal health.

As a result, we need to get omega-3 and omega-6 fatty acids from the diet. But exactly how much do we need? Surprisingly, that question is hard to answer.

Adequate intake levels of α-linolenic acid the primary dietary source of omega-3 are 1. If we look at a collection of recommendations from different countries, we tend to see intake targets around 1.

When converting this to a daily target for total fat intake, we have to consider the concentration of omega-3 and omega-6 fatty acids within the actual foods and oils you consume.

If you thought this section would bring a precise target with more clarity than the previous section, brace for disappointment. We see all sorts of interactions among micronutrients, such that some are absorbed less in the presence of certain micronutrients, but absorbed more in the presence of others.

Based on a combination of biochemistry and intestinal physiology, we know that dietary fat should facilitate the absorption of fat-soluble vitamins which are vitamins A, D, E, and K.

However, when it comes to the research exploring exactly how much it matters and exactly how much dietary fat is needed and when it should be ingested , the findings are all over the place.

Some studies have indicated that the fat content of a meal meaningfully impacts vitamin E absorption 6 , while other studies find no substantial impact 7.

It gets even messier when branching out from single-meal absorption to longer time scales several months when assessing dietary fat intake and adequacy of fat-soluble vitamins, because fat-soluble vitamins can be stored in body fat and other tissues for later use.

We know that medical conditions involving fat malabsorption considerably increase the risk of fat-soluble vitamin deficiencies 8 , so we know by extension that a zero-fat diet would not be suitable for enabling adequate absorption.

However, when it comes to supporting fat-soluble vitamin absorption, a clear and concise daily minimum fat target eludes us. Many studies have shown that reductions in fat intake can lead to reductions in circulating sex hormone levels.

Few lifters would consider that to be an ideal outcome, but we also know that decreased sex hormone levels are commonly observed in a variety of competitive endeavors, such as endurance sports and physique sports.

Back in , Whittaker and colleagues conducted a meta-analysis exploring the relationship between dietary fat intake and testosterone levels in men They ended up including six studies with total participants, and the analysis revealed that low-fat diets induced statistically significant reductions in total testosterone, free testosterone, dihydrotestosterone DHT , and urinary testosterone, with non-significant reductions observed for luteinizing hormone and sex hormone binding globulin.

Having said that, there are a few important caveats to highlight. First, it would be inaccurate to say that more fat is always better, as excessive carb restriction has also been shown to reduce sex hormone levels.

To account for uncertainty, imprecision, and inter-individual differences, I personally would expand this range to around grams per day.

Samples Prospective Urban Rural Epidemiology PURE was an international multi-center prospective study. Survey Methods We gathered information about demographics, physical activity level, diet, smoking and other risk factors using a uniform questionnaire for adult participants, following the same procedures and methods used in studies in the other international centers.

Physical Examination Participants were measured in casual clothing without shoes in a relaxed standing position. Laboratory Measurements A hour fasting blood sample was collected, including fasting blood glucose FBG , serum triglycerides TG , serum low density lipoprotein cholesterol LDL-C , and serum high density lipoprotein cholesterol HDL-C levels, and measured in a centralized, certified laboratory.

Definition of CVD Risk Factors In the present study, we adopted the definition of CVD risk factors proposed by the Seventh Report of the Joint National Committee JNC7 [ 18 ].

Results Participant Characteristics The characteristics of the study participants and the prevalence of CVD risk factors, for the entire study population and stratified by gender, are presented in Table 1.

Waist circumference and waist-to-height ratio are better predictors of cardiovascular disease risk factors in children than body mass index. Both have their purposes, but the former is useful for activity, the later is useful as insulation and for reserves.

Unfortunately, most Americans are carrying around quite a lot of the later and not enough of former. Fascinatingly, over the course of a week, that means an extra 3. And what will that extra 3, calories a week burn?

Amazingly, 3, calories just happens to be the same amount of calories in a pound of fat! The average person can lose about a pound of fat per week with proper exercise and nutrition until approaching a healthy weight. But, the average person through specific exercise involving strength training will only add a pound of muscle each 4 — 6 weeks.

Instead of being the equivalent of the hare sprinting to achieve fitness goals at an unsustainable diet and pace, slow it down a bit more to the pace of a tortise. Add in a good amount of strength training and make sure to have plenty of protein in the foods you eat to allow the body to create more muscle.
