Blog Post by Coach JulieNCI Certified Nutrition Coach L1 and Mindset Coach Artificial sweeteners have been the bastard of the nutrition and fitness industry lately. They are getting the blame for cancer, gut health issues, disordered eating and blood sugar spikes. But what is the truth about artificial sweeteners.
The three most popular artificial sweeteners on the market today are: aspartame, sucralose, and saccharin. These sweeteners are often found in popular foods that have been reformulated into a “zero sugar” version which often results in a reduced calorie option of the popular alternative. For example, I enjoy Sprite Zero because it offers a “treat” with dinner for zero calories where a can of Sprite is about 120 calories. Sprite Zero contains aspartame to give it the sweet flavor without the calories mounting. These sweeteners have been on blast by the media about their “harmful” effects for years. The issue with media, is that it is almost always sensationalized to gather attention. Clicks and shares usually mean income for news media so you will often see stories overly sensationalized to garner more attention. You can see this very clearly in the amount of stories on news outlets about terrorism and violent crimes. It has created an attitude that the world is a super dangerous place, but actual studies have shown that crime has been down the last several years. The WHO (World Health Organization) came out a few years ago and said there MAY be a link between artificial sweeteners and cancer risk. This simple, yet uncertain claim has sparked the media firestorm that has created a line in the sand between nutrition researchers and cherry picking, media outlets that are trying to boost their bottom line. In an great article by Mike Matthews of Legion Athletics, Mike shows a great graphic on where the WHO categorized artificial sweeteners. He stated, “The WHO is placing aspartame in Group 2B. Thus, according to the WHO’s assessment, aspartame is about as likely to increase your cancer risk as aloe vera, carpentry, and eating pickled vegetables.” I’m not real sure about you, but if I find joy in one Sprite Zero per day, I feel relatively safe doing so. There have been recent studies lately that are showing that there is NO association between these sweeteners and cancer. In a recent news story on Barbend, the study has dispelled the WHO’s previous claims and actually shown that zero calorie sodas may be beneficial for health if it’s used to replace regular soda for weight loss because it aids in weight loss and reduces the overall sugar intake. The other big concern surrounding artificial sweeteners is their effect on gut health. There have been small sample studies done in rats on the effects of sweeteners on the gut microbiome. The issue is, rat studies don’t always translate well to humans. Most of these studies were feeding the rats toxic amounts of sweeteners that would translate to obscene numbers in humans. A recent article on StrongerU as well as an article on BioLayne, show the limitations associated with the rat studies. Overall, the studies on gut microbiome have been widely inconclusive. Some social media influencers have argued that these sweeteners promote obesity by increasing cravings. Here’s the thing, this argument also has no conclusive evidence of this. As a nutrition coach, I believe if you maintain a 80-20 diet in nutritious foods and use these zero calorie foods and drinks as a “treat” that subs for the higher calorie options, you’re going to be just fine. I don’t believe that these foods drive cravings more than any other food option. Realistically, this argument could be made about most highly processed, higher carb foods, they also tend to promote cravings because carbs do not offer the satiating effect you receive from protein. With all of the recent research, I’m not willing to tell any of my clients to stop choosing zero calorie sodas over regular sodas. I would caution that too much of any good thing can be a bad thing. The studies have not shown conclusive evidence of causing harm in small amounts. If you are drinking obscene amounts of these sweeteners, we need to have a different conversation because I would assume you’re having health issues. Those issues would be associated with dehydration NOT the artificial sweeteners. Overall, the benefits of artificial sweeteners far outweigh the potential risks, if used in a reasonable amount.

Have you ever been told the reason you’re not losing weight is because “you’re eating too little”.
If so, I am also sure you have been told your body has gone into “starvation mode”. Where people tend to explain it, as your body is holding onto all your body fat because you haven’t been eating enough calories. Spoiler Alert: I’m here to explain to you why this is in fact a myth. As everything you hear in the fitness and health industry there is a sliver of truth behind this statement. In fact, I myself am guilty of using this phrase in the past. Thankfully I have continued to learn and research the science of our metabolism. Next let's break down the common definition of “starvation mode”. What is Starvation Mode? Starvation mode is not a scientific term. It is a popular phrase used to imply that when you cut calories too low, your body goes into a protection mode, slowing your metabolism and calorie output so that you stop losing weight. This concept is rooted in your body's survival mechanisms. If you ever found yourself without food for long periods of time, it would not be beneficial for your body to continue to burn calories at a normal rate; instead, your metabolism would shift to preserve as much energy as possible to prolong your life. But starving to death is not quite the same thing as dieting and you will still lose weight in the process of wasting away without food. How Long Can You Survive Without Food? With access to water and electrolytes, your body can survive for quite some time without food, depending on the person and how much body fat you have. Some research suggests that you can go more than a month without food. And in some religions, long fasts are commonly practiced with potential health benefits. Starvation mode is not a real term, but metabolic adaption is, and it’s a known phenomenon. How drastically it affects your weight loss progress is another story. Your body can compensate for decreased calories by slowing your metabolism down as much as 30% through adaptive thermogenesis. But the effects of adaptive thermogenesis are typically short-lived, and for most the difference could be as little as a 5% decrease in basal metabolic rate (BMR), and it does not indicate a damaged metabolism. So what is the verdict? In all of the studies referenced to support starvation mode, weight loss was a factor. And it is crucial to note that any weight loss can cause you to have a lower BMR - since it just takes less energy to move around a smaller object. Why You're Not Losing Weight and How to Fix it If you find that you’ve hit a weight loss plateau, it does not mean you are in starvation mode. Some more common factors are likely at play, including the following: You're Not Tracking Your Food Intake It's pretty impossible to know if you are in a calorie deficit if you aren't tracking your food intake. Before assuming something else is at play, keeping an accurate food diary is the best place to start. Even if you've been tracking, take a look at how diligent you are being with this habit.
You can also use your tracking app to get weekly calorie and macro averages - this is the best way to see how well you’ve stuck to your diet consistently, as well as where you could use some work. You're Not Eating the Right Amount of Calories Typically, if you aren't losing weight, you are eating more calories than you think. Or if you've recently lost weight, you likely have a new maintenance calorie amount and may need to eat fewer calories to continue losing. This is why many popular weight loss plans will use a phased approach to cutting, helping you to stay in a calorie deficit and continue losing weight with incremental calorie cuts. Start by figuring out how many calories you need to eat a day to maintain your current weight and then calculate your new weight loss calorie needs from that starting point. You're Always on a Diet It might also just be that your body needs a break. If you've been dieting for more than a few months, it might be time to give your body time to adjust to your maintenance calorie level. Jumping from one diet to the next and constantly trying to cut calories can do more harm than good. It is much easier to stick to a diet and continue to get results if you understand how to maintain results in the first place. Been on a really low-calorie diet for a while and scared to add calories back in? Try upping your intake a few hundred calories a week to start, until you reach your maintenance level. And then stick to your maintenance for at least a month to give your time to adjust and reset your metabolism. You're Too Focused on the Scale Oftentimes dieters are focused solely on fat loss, but their total body composition is crucial to getting better results and making them stick. Not to mention, if you are cutting calories too low for too long, you’re at risk of losing precious calorie burning tissue - your muscle. Gaining muscle is essentially the opposite of “starvation mode”. Your muscle mass is the biggest determinant of your metabolic rate, and the more you have, the more you can eat and maintain your weight. Plus, muscle is the tissue behind that lean, toned look most of us are striving to achieve in the first place. While muscle growth is typically achieved through weight gain, which would ultimately increase your metabolism even further, it is possible for some people to build muscle in a calorie deficit. But at the very least, you should be focused on protecting your muscle while dieting. To keep your lean mass intact while dieting, be sure to incorporate the following:
What are the Minimum Calories for Weight Loss? While starvation mode may not technically exist, starving yourself to lose weight is still not recommended. A very low-calorie diet may work at first, but it’s likely not going to do you favors in the long run. It can be dangerous for some people, lead to disordered eating habits, and does not typically lead to sustainable results, since most people do not change bad habits once they resume eating again. In addition, extreme dieting is impossible to maintain, causing painful hunger cues, irritability, mood swings, decreased energy, poor concentration, and sucks your willpower dry, all of which makes sticking to a diet that much harder. Instead, stick to a more attainable approach to dieting with no more than a 15-20% decrease from your estimated daily energy needs. Slow and steady weight loss of 0.5 to 1% body weight per week is much easier to keep off and you will be much happier and more successful with a more measured and sustainable diet plan approach.

Blog Post by Coach JulieNCI Certified Nutrition Coach L1 & Certified Mindset Coach  Wegovy and Ozempic are both GLP-1 (glucagon like peptide). With GLP-1 drugs, you will lose muscle mass if you are not doing some sort of resistance training. “Much of the "weight loss" resulting from GLP-1 agonists is the loss of muscle, bone mass, and other lean tissue rather than body fat (Ida, et al.).” When taking GLP-1 drugs it’s important to focus on getting adequate protein to at least maintain muscle mass. (Usually .75g of protein per pound of lean body mass is adequate. If your goal weight is 150 pounds that means 113g of protein per day.) A significant loss of bone mass, for example, predisposes serious bone diseases such as osteopenia and osteoporosis. And a significant loss of muscle mass lowers metabolic rate (increasing the risk of weight regain), raises the risk of falls, and impairs function and quality of life. Research has found that when people stop taking Wegovy/Ozempic, they rapidly regain weight. (Diabetes, Obesity and Metabolism: Journal, June 2022) Experts say this is because the drug is not a cure and it does not prevent the metabolic adaptation that occurs during weight loss. A study published in April 2022 which sought to examine changes in body weight and cardiometabolic risk factors upon the termination of the drug, found that after a year people had regained two-thirds of the weight they had lost. The positive changes they had seen in cardiometabolic risk factors like blood pressure, blood lipids, HbA1c, and C-reactive protein had similarly reversed.According to the study authors, these findings reinforce the need to continue treatment in order to maintain the benefits of the medication. (Diabetes, Obesity and Metabolism: Journal, April 2022) The fact that people may need to stay on Wegovy indefinitely in order to maintain the weight loss has raised concerns about long-term use. (NPR, 2023) As a nutrition coach, I have been asked several times about these two drugs. I always suggest talking with your doctor about this and making sure that this is the right answer for you. My opinion though is to always work on lifestyle, diet and fitness interventions first. I would invest in a coach before I spent the money on this very expensive drug. If you have further questions, shoot me a DM, we’ll talk. EVERYBODY IS TALKING ABOUT IT. Unless you follow Dr. Oz, the #ketowarriors, or the descendants of Vegan Gains — you’ve heard that a “calorie deficit” is the key to losing fat. We’ll get into details later, but to refresh: a “calorie deficit” simply means your body is burning more calories than you’re consuming (i.e., calories out > calories in = weight loss (few exceptions)). A “calorie surplus” means you’re burning fewer calories than you’re consuming (i.e., calories out < calories in = weight gain). And if you’re eating at your “maintenance calories,” you’re burning around the same number of calories as you’re consuming (i.e., calories out = calories in = maintain stable weight). Now, I could get deep into the minutia of calories in calories out and how your body “burns” calories, but you probably don’t care about the science. What you do care about: me knowing the science and giving you the actionable steps to put into practice. And that’s exactly what I’m gonna do, so take a quick glance at this pretty picture and let’s keep it movin’.  That’s the why. Now, I’ll share the how.
For the record, I’ve never seen another fitness coach put this information out for free. This is exactly how I set up a calorie deficit for my online coaching clients, so listen up. STEP 1: BUY SCALES. Buy a bodyweight scale and a food scale. These are reasonably cheap and some of the best investments you can make for managing your body. Plus, there are two things humans suck at: estimating and remembering data. In fact, one study on daily food reporting showed even dietitians to be off by up to 800 calories. Some non-dietitians were off by over 1,000 calories! So, yeah. Buy the scales so you don’t do this. STEP 2: DOWNLOAD A FOOD TRACKING APP. I recommend FatSecret or My Fittness Pal to my clients. Don’t use the macro calculator for any of them as that’s the point of this post ⏤ this way is more accurate. MFP might just be more accessible in terms of how to use the app for some people. However, another downside of MFP is their calories can be off with some of their foods due to user inputted data. Just make sure your total daily macros match up to your total daily calories and you’ll be good to go. Any tracking app or using a pad and pen (if you’re a neanderthal) will work just fine. We’ll cover your macros (proteins, carbs, and fats in a bit). STEP 3: EAT NORMALLY AND TRACK EVERYTHING. Without drastically changing how you currently eat, track every single thing (very important this is accurate!) you put in your mouth for at least four days (preferably three weekdays and one weekend day). I say to eat normal because you want to find your current baseline. If you go changing everything you eat, you’ll skew your results. And when I say track everything, I mean EVERYTHING — alcohol, condiments, oils, drinks, supplements, butter, sauces, dessert, etc. STEP 4: AVERAGE OUT YOUR BASELINE. After tracking at least four days, find the average number of calories you ate during that time period. For example:
STEP 5: REMAIN CONSISTENT WITH TRACKING WEIGHT AND FOOD FOR 14 DAYS.Try to hit within +/- 50 of that average calorie amount (2,150 – 2,250) every single day for the next 2 weeks (including weekends!) AND weigh yourself every day in the morning – before you eat and after you take your morning dump. It’s important you try to mimic each day so you can get a realistic idea of what your “typical” intake and weight would look like, i.e., don’t do this during vacation. STEP 6: ANALYZE WEIGHT TRENDS. Given that you followed step 5 correctly, we should now see a trend in what your weight does based off how much food you’re eating. If you’re eating ~2,200 calories per day and your weight is trending downward (not down every single day because weight fluctuates) over the course of two weeks — you’re likely in a calorie deficit. If your weight is staying about the same (within a pound or so), subtract 250 calories from your daily calorie goal and keep consistent. This means you are eating around your maintenance calories. If your weight is trending upward, take away 350-500 calories per day (you’re in a calorie surplus). -Coach Kayli |
