For a long time there was a war on fat, like over 30 years long. I’ve talked a lot about the importance of reading labels and understanding what you’re consuming. Not necessarily saying no to the processed food, but understanding or knowing what is in it. Well, taking that a step further – we need to also understand that the guidelines that back those labels up are created by governing bodies that may or may not benefit by creating certain guidelines or encouraging certain studies.
I’m not saying that the FDA or USDA or other regulatory groups are bad, but I am saying that the information can be misleading or a generalization in some cases.
A good example: the nutrition label you see on your boxed and canned goods is based off of a 2,000 calorie diet. This means the percentage listed as daily value is based off of 2,000 calories, but you may not be eating 2,000 calories – you may be consuming more or less.
Another example: the most recent guidelines by the USDA have a caloric recommendation for individuals based on gender, age and activity level with all numbers being whole, round numbers. These numbers are only below 1,400 daily calories for children under the age of 6, sedentary males peak at 2,600 calories for a 19/20 year old with sedentary females peaking at 2,000 calories for ages 19-25 – individuals who are more active peaked calories up to 3,200 daily. The guidelines state that the sample bodies used to determine were an average height and a “healthy” weight (page 77-78).
“For adults, the reference man is 5 feet 10 inches tall and weighs 154 pounds. The reference woman is 5 feet 4 inches tall and weighs 126 pounds.”
I’m 5’4″ and I weight about 138 pounds. I’m roughly 17% body fat, which is lean and considered athletic for a female. My measurements are small. I don’t fit the sample body. I also don’t know many “healthy” men that would fit this sample body either.
The first dietary guidelines were rolled out in the 1980s and at the time, the biggest concern was heart disease and heart attacks. Ultimately, the first guidelines recommended against all fat and foods that had cholesterol like red meat. However, more research has shown that not all fats are created equal and that dietary fat is necessary for bodily function. In the most recent guidelines for 2015-2020, it’s stated that saturated fat consumption should be 10% or less of overall calories consumed (page 15 footnotes). It’s also recommended that you replace saturated fats with unsaturated fats.
Before we get ahead of ourselves, let’s talk about fats. Have you ever heard about triglycerides? It’s possible that your doctor has mentioned this term before when discussing blood work and overall health. These are the most common dietary fat we eat. This is also the form that fat is stored in our bodies.
The science of triglycerides
Triglycerides are a molecule consisting of 3 fatty acids attached to a 3 carbon glycerol backbone (Thompson & Manore, 2015). They are classified by their chain length (how many carbons are attached), their level of saturation (how much hydrogen is attached to each carbon) and their shape.
The first way to classify – chain length. The first thing we learned in biology is that structure determines function – if you have a wheel it can move things forward, right? It can’t make things fly. There are three chain lengths: short (6 or fewer carbon), medium (6 to 12 carbon) and long (14 or more carbon). The lengths determine the method of fat digestion and absorption as well as how the fat works within your body. As you imagine, the shorter the chain, the faster the digestion and absorption (Thompson & Manore, 2015).
Now, saturation level. What’s the difference between these two kind of fats?
The simple answer – saturated fatty acids have closely packed molecules because they lack a double bond that would “space” them out. This means they can solidify at room temperature, example: a jar of coconut oil. unsaturated fatty acids do have a double bond, which prevent them from solidifying at room temperature, example: olive oil (Reece, Taylor, Simon, Dickey, & Hogan, 2015).
Lastly, shape – the carbon molecules impact the shape. The lack of the double bond in saturated fat allows the chain to be straight and pack tightly together. The double bond in unsaturated fat prevents the chain from being straight and actually adds kinks, which makes them liquid at room temperature.
But what about bottles of coconut oil at the store, how are those liquids? Coconut oil that is liquid at room temperature is manipulated during manufacturing. The removal of natural fatty acids that solidify allow liquid coconut oil to be just that. Lauric acid, the fatty acid in coconut oil known for its health benefits like being a germ killer, is actually removed in this process. This is because it’s melting point is over 100 degrees Fahrenheit. To read more about the production, safety and use of liquid coconut oil check out this article.
Coconut oil isn’t the only thing that is manipulated on the market. Unsaturated fats can also be manipulated by food manufacturing in a process called hydrogenation, which started in the early 1900s (Thompson & Manore, 2015). This process adds hydrogen molecules, which in unsaturated fats causes the double bonds to be partially or totally removed allowing the fat to become solid and store more easily for a longer period of time.
This is also where we get trans-fats, which actually is describing the double bonds in the molecule. This kind of fat is found mostly in foods that are manipulated, although a small amount of natural trans fatty acids are found in cow’s milk and meat.
Now that I’ve confused you, triglycerides do contain essential fatty acids that are important for health (Thompson & Manore, 2015). Essential fatty acids (EFA) are obtained from the foods we consume – our bodies cannot produce them. There are two groups of them: Omega-6 and Omega-3.
Omega-6 Fatty Acids have a double bond 6 carbons from the end (omega = end of the chain, 6 = number of bonds away from the end). Linoleic acid is an omega-6 that is essential for human health. This is found in vegetable and nut oils like peanut oil, sunflower oil, corn oil and soy.
Omega-3 Fatty Acids have a double bond 3 carbons from the end. Alpha-linolenic acid is the most common in our diets and primarily comes from plants like leafy greens, walnuts, flaxseeds.
Why are EFAs important?
They’re precursors to biological compounds found in every cell in the body that regulate cell function.
Why is fat in general important?Fat provides energy; it has 9 calories per gram, which makes it the most dense energy source. Our bodies use fat when we’re at rest and during physical activity.
- Fat helps transport vitamins A, D, E and K throughout the body, which help regulate functions like calcium absorption and utilization, cell membrane protection, blood clotting, bone health and vision.
- Fat regulates our hormone production and cell function. *
- Fat contributes to satiety, which means we stop eating sooner and helps us feel full longer.
Fat Importance on Cell Function and Hormone Production
This is something I talk a lot about with my clients. Fat is important because of the reasons listed, but as someone who works predominately with women this is something I want to drive home with them. There’s no reason to fear dietary fat, but we do need to moderate it. Phospholipids are a major component of our cells (Reece, Taylor, Simon, Dickey, & Hogan, 2015). These are similar to fats, except they contain two fatty acids attached at the glycerol, not three. Steroids are hormones produced in the adrenal cortex, cortisol is an example of a steroid hormone, which regulates carbohydrate metabolism and provides an anti-inflammatory effect on the body.
Fat -loving and the Ketogenic Diet
As the war on fat has started to settle, the rise of high fat diets like the ketogenic diet have started to become increasingly popular for fat loss; however, this style diet isn’t for everyone and should be monitored because of other potential health outcomes.
So what is the ketogenic diet?In simple terms it’s a high fat, very low carbohydrate (~20g or less daily), moderate protein diet that has been utilized to help with refractory epilepsy since the 1920s (Gupta, et al., 2017). It’s especially helpful for children with epilepsy, but according to the Epilepsy Society, adults may also benefit from it. The ketogenic diet has also been found to assist with fat loss in individuals who are obese lose as well as help manage other disorders like polycystic ovarian syndrome (Gupta, et al., 2017). However, be reminded that less extreme diets that moderate calories will also result in fat loss as long as the individual adheres to it and a diet that moderates carbohydrate intake may also assist with PCOS.
So how does the ketogenic diet work?
Our bodies utilize carbohydrates that have been broken down to glucose as a main source of energy (Thompson & Manore, 2015). While our bodies also use fat as fuel, glucose is favorited by red blood cells, some nervous tissue and our brains for energy.
When we don’t take in enough carbohydrates…. let me pause…enough carbohydrates doesn’t mean hundreds of grams daily. Enough carbohydrates could be 100g a day depending on the age, gender and activity levels of the person. Ok continuing…our bodies start looking for another fuel source. In the process of ketosis, the liver converts fat into fatty acids and creates ketone bodies or ketones that will be utilized as fuel. These ketones are a natural appetite suppressant that can help control nutritional intake (Thompson & Manore, 2015).
What about the keto diet is beneficial to different populations?
The effects on the “central nervous system, cellular metabolism and metabolic pathways, have shown promising results in a variety of neurological disorders, traumatic brain injury, acne, cancers, and metabolic disorders (Gupta, et al., 2017).” “The ketogenic diet alters the energy metabolism in the brain, therefore altering brain excitability,” which impacts how cells communicate with each other and regulate the CNS (Lee, 2012).
Is there one way to practice keto?
This is a tricky question. The classical diet of keto that is utilized with epilepsy patients suggests strict ratios of fat, carbohydrates and protein at every meal. It also includes little protein and carbohydrate because of the body’s ability to be “knocked out” of ketosis by too many of either.
The medium chain triglyceride (MCT) diet allows for a little more carbohydrates and protein. This version provides some flexibility and allows MCT oil to be used a supplement. Nutrients are also calculated by the percentage of calories for each group, meaning it’s not a specific number of grams, but a percentage of overall calories.
If keto can be helpful, why shouldn’t everyone utilize it?
A true ketosis diet should be monitored because of higher risks for other health concerns like osteoporosis (weak and brittle bones), hyperlipidemia (abnormally high fat in the blood), nephrolithiasis (kidney stones). Some of these health concerns can onset as we age, but nutritional deficiencies can increase risk. This means that supplementation is necessarily because there is a lack of diversity by lowering carbohydrate intake. This would be a recommendation for many people seeking fat loss with any diet – supplement appropriately.
The use of carbohydrates in our diets isn’t just for daily function like walking, talking and sitting; they’re also used for fuel during prolonged period of activity and protect again the use of stored protein as a fuel source i.e. muscle loss (Thompson & Manore, 2015). When our bodies don’t have enough carbohydrates our bodies continue to find fuel sources, and while in a perfect world we imagine the body will find stored fat to utilize, it will also find stored protein. Not only does this result in muscle mass loss, but it can weaken our immune systems and prevent optimal function. However, this kind of loss can be associated with too little calorie intake because a nutrient group has be drastically decreased or eliminated.
If ketone levels are too high the blood can become very acidic and can lead to ketoacidosis. This actually prevents optimal body function and ultimately can lead to damaged tissue.
Why don’t I believe the ketogenic diet should be prescribed to everyone?
My personal belief is that the ketogenic diet should be utilized for clinical conditions like epilepsy and other cognitive or metabolic disorders. I do believe that some people feel better on lower carbohydrates, but lower is relative.
I had a client who recognized she felt physically better on higher fat, moderate carbohydrate and protein. Her macros were 75F/100C/147P or 1,663 calories. Her goal was fat loss and this was a deficit for her. On days that she would run long distances (over 4 miles) she would increase her carbohydrates between 20-40g because it helped in those runs.
Yes, I eat processed food and things with real and artificial sweeteners in them, but I also know that’s not for everyone. I know not everyone can moderate these foods and that’s completely ok. I do believe that one way to work towards creating a healthier food plan is to examine the carbohydrates that are you taking in and how they make you feel. I ask my clients to do this often by making a list or notes when they recognize they feel bloated, jittery, exhausted, fatigued, etc.
Carbohydrates breakdown to sugars like stated above so in many cases they feel these things because of 1. too much sugar (real or added) 2. too many overall carbohydrates 3. the kind of carbohydrates they’re consuming (simple versus complex). I don’t think extremes need to be implemented to see change or progress unless specified by a physician.
Mentally, I think elimination diets that pull full groups of foods can be harmful over time to the relationship that we have with food. Creating a balance lifestyle also means enjoying foods that tastes good, but isn’t necessarily the greatest for us, but understanding that moderation is key. Eating out, attending and participating in parties and functions is a part of life and experience. While many suffer from auto immune disorders or illnesses that force them to create alternative eating styles to manage their health, many don’t need extreme measures.
Health coaches, lifestyle coaches, personal trainers, wellness coaches, etc. people assisting others like I do, should be encouraging individuals to bring in all their resources to find what ultimately works for them in a reasonable and safe way.
We shouldn’t fear fat in our diet, but we also shouldn’t fear other nutritional groups either – we just need to better understand them.

Don’t doubt yourself. Try to not let the doubt of others fill you either. But, are you ready for the things you want to accomplish? I’m not just talking about your health, but in general, everything you want – do you really want to put your words into action or are they just words right now?
I talk about goals a lot because I feel better and more in control when I have a goal in mind – either continuous or deadline driven. I have a mostly Type A personality meaning I like structure, but I’ve also figured out how to go with the flow and be more fluid with my methods and goals. However, not everyone is like this and that’s completely okay.
Whether you realize it or not, as you think about tomorrow, next week, next month and next year you are going through The Stages of Change Model. I first learned about this model in my psychology course last fall, since then, it’s been discussed in five out of nine of my program’s classes.
In 1979, James O. Prochaska developed a transtheoretical model of change in a study that compared 18 different therapy systems and reviewed about 300 therapy outcomes. His model categorized the systems of therapy into five processes of change. “These processes are differentiated along two dimensions.”
1. verbal and behavior categorized the change process according to application – therapy that relies of verbal interaction or behavior manipulation.
examples: feedback and awareness of a problem like smoking, education about a problem like smoking
2. experiential and environmental categorized the change process by the individual’s experience or the individual’s surrounding environment
examples: finding new coping mechanisms instead of smoking, removing triggers like ashtrays and cigarettes
In 1982, Prochaska and Carlo C. DiClemente worked together using Prochaska’s model to examine self-change and therapy change in smoking behavior. Their study was titled: Self-Change and Therapy Change of Smoking Behavior: A Comparison of Processes of Change in Cessation and Maintenance. It was published in Addictive Behaviors volume 7 that year.
The sample was small, but there was a mix of gender (29 males to 34 females). Smokers who quit on their own (n=29) were compared with two different groups of smokers: an aversion group (n=18) and a behavioral-management group (n= 16). The sample was random with self-quitting participants recruited through various methods like fliers, advertisements and newspaper – remember, this is 1982. Participants from the two therapy groups were recruited randomly as well through fliers handed out after meetings.
Within seven weeks of quitting all subjects were given a change-process questionnaire verbally with all responses recorded on tape. They also answered a variety of smoking history and demographic questions. They were told they would be interviewed a second time within six months.
From these responses, Prochaska and DiClemente looked six verbal and four behavior process of change, and three stages of change (decision to change, active change and maintenance).
Here’s what they found:
1. Attempts to quit among the three groups were similar, gender didn’t necessarily make a significant difference among the three groups either.
2. The group that did see signification differences (p < .01) were from the behavioral-management group. These participants were older with an average age of 42, the age range varying from 30.4 years to 53.6 years. They smoked for a longer time than the other two groups with a mean of 25 years and a years-as-a-smoker range from 14 years to 36 years. These participants were more invested in quitting this time.
When looking at the different processes of change they found:
1. Individuals who quit on their own rated feedback, stimulus control and social management as less important than the other two groups.
2. All three groups rates self-liberation as quite important, however, the aversion group said it was more important than the other two groups.
3. The behavioral-management group rated counterconditioning as more important than the other two groups.
During the follow up they found:
1. Two-thirds of all subjects remained abstainers.
2. There were no differences in proportion of successes and relapses for all groups. Looking at the variables such as age, education, occupation, years smoking, etc. didn’t have any significance.
When speaking to participants who relapsed:
1. They struggled to find other coping mechanisms to deal with personal problems like consistency with exercises or health-related physical activity.
2. Some said they believed the habit was under control even with the relapse.
3. Some said they missed the habit.
Prochaska and DiClemente conducted new study a few years later where they used a sample of 872 smokers. This study was an extension of the first.
This model of behavior change is taught in all areas of the health field from psychology to sociology to nursing and public health. While I don’t blatantly tell my clients they are going through this model when we have our screening, I assess them with this model.
Many who talk with me are usually past precontemplation and contemplation – they’re ready for action, however, some are still determining the right course of action. It’s not about how bad they want change, it’s about being ready for change and finding the right way to go about making changes to their lifestyle.
There are some cases where a client and I will discuss their goals and I’ll say, I think these are great, but be aware that it’s possible that they may change, that you may realize there are other things that will assist with these goals that may become more important for the time being. This isn’t too discourage them, but to let them know that I’m acknowledging that goals can change and that as their coach, I think it’s okay. An example may be the client who says they want to lose weight, but doesn’t realize that they have a poor relationship with food. The goal eventually will be weight loss, but for the moment it’s about working on building a better relationship with food so it’s not used as a coping mechanism or so that they don’t restrict themselves and feel incapable of adhering to their nutrition goals. We will work on stress management, meal planning, meal creation and setting micro-goals that work towards a healthy lifestyle that assists weight loss for eventual weight loss over time.
It’s completely okay to not be ready for a goal, it’s also completely okay to change your immediate goals in order to work towards the bigger picture.
When we think about our goals and what we want out of life, what direction we want to take, we also need to look at the driving force behind it. I always ask my clients why their goals are their goals. The responses have ranged from “I want to be able to get on the floor with my kids” to “I want to be stronger”. There are also some who say they want to lose weight because they believe they will be happier or feel better when they have. I have said to them that size doesn’t equate happiness, but if being a healthier smaller size means that they will be more outgoing and their mental well being will improve – then yes, it’s reasonable to say that you believe you may be happier when you’ve lost weight.
But for all clients, regardless of their reasoning behind their goals, I ask them to dig deeper to make sure that their goals are truly something they want.
Living a healthy lifestyle is more than the time that it takes to lose weight. It’s more than the time it takes to learn to allow freedom and flexibility. It’s about building lasting habits and truly implementing and learning positive behaviors.
Now, that’s not to say that you won’t ever “mess up”, you won’t ever not want to eat off plan,. It’s human to have set backs. It’s human to take a break. It’s crazy to think that every day has to be perfectly lived towards these goals. I don’t believe that’s realistic, but it’s about small behaviors that add up over time that make meaningful change.
I challenge myself often to remind myself why I’m back in school, why I’m coaching, what health means for me in this moment. I want you to think about your why’s, your life, your plan – are you ready? Do you have the support around you? Do you truly support yourself to make the changes necessary to accomplish whatever it is you want to?
I hope you can see the greatness inside you. There’s nothing more rewarding than the light bulb going off when something finally clicks for a client or they start seeing the greatness I see in them.
I wish for you empowerment in the New Year. I wish for you that you allow yourself time as you start to figure out your next steps. Don’t rush – good things can come slowly, we just need to learn to be patient.
My friend posted on instagram that we she was going to start cutting out alcohol, soda and coffee from her diet; all at once. This is a big deal for her, and a big deal in general. Cutting things that we find to be vices can be difficult for anyone, no matter what it is. Lately, I’ve been on a coffee and alcohol kick: Iced Caramel Macchiato to Saranac Shandy brew. When I saw her post, I commented and said we should do it together. While alcohol hasn’t been a big part of her diet, she said that soda and coffee is something she’s drinking just to drink something, not because she’s craving it, but just because ‘why not’?
Not only are there a million things in these drinks that we can’t pronounce, there are a lot of empty calories that we have the ability to consume than if we were to just drink water with fruit or cucumber slices in it.
So here’s the challenge:
- 30 days of increased water intake
- No soda, coffee or alcohol of any kind- light beer means nothing here
- At least 60 ounces a day
- Report to each other throughout the challenge
I’m hoping this helps me reset from all the cream and sugar loaded drinks I’ve been consuming lately. I also am hopeful that it will help be de-bloat a bit. Other benefits from drinking water aside from hydration can be clearer skin, eating less, helps energize your muscles, help kidney function. I’m sure the list can continue on.
This brings me to today’s 100 Happy Days post. Day 29: friends who support you and who you can support. Body resetting with my college freshmen roommate. Ohio to Massachusetts, we’ve got this! #healthylifestyle #100happydays #happinessdoesntcomeinajar #restyourgut
Here’s yesterday’s post too. Day 28: fluffy pillows and comfortable bed after a long day! Not everyone has this luxury and I’m grateful for it.
