What exactly is your Metabolism & what does it do for you?
Imagine your body is like a machine that needs fuel to run, just like a car needs gasoline. Metabolism is like the engine of that machine. It's the process in your body that turns the food you eat into energy that your body can use. You see, every time you eat something, your body breaks down the food into smaller pieces called nutrients. These nutrients include things like carbohydrates, proteins, and fats. Your body uses these nutrients to do different things, like helping your muscles move, your brain think, and even your heart beat. Now, think of your metabolism as the way your body converts these nutrients into energy. It's like a factory inside you that takes in the nutrients and turns them into the energy your body needs to function. This energy helps you do everything from running and playing to growing and even sleeping! The metabolism is always working, even when you're sleeping or sitting still. It's a busy process that happens in every cell of your body. Some people have faster metabolisms, which means their bodies convert food into energy more quickly. Others have slower metabolisms, so their bodies convert food into energy more slowly. Different things can affect your metabolism too. For example, when you exercise, your metabolism speeds up because your body needs more energy. That's why it's important to eat healthy food and stay active, so your metabolism can work efficiently and keep you feeling good. So, in simple terms, metabolism is like the engine that converts the food you eat into energy for your body. It's what keeps you going and helps you grow strong and healthy! 8 Simple Ways to Speed Up Your Metabolism: Your metabolism doesn’t slow down due to age until your reach your 60s If it does slow down it’s due to a significant change in your lifestyle. The most common reason being you lost muscle & your actions led to a slower metabolism. 1. Stop crash dieting.
- Increases appetite + cravings - Decreases energy expenditure 5. Drink ½ your BW in oz of water per day.

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.
