Tuesday Tip: Fat burning isn’t Fat loss

Tuesday Tip: Fat burning isn’t Fat loss 🔥

Many of you will be familiar with fitness trackers that tell you how much of your work out was in ‘fat burning’ mode etc. You’ll also see workouts and supplements marketed as ‘fat burning’. What’s important to remember is fat burning and fat loss are not the same thing.

Fat is a great energy store for the body – a a lean adult man can store around 130,000 cals in fat (enough to survive for 65 days) but of course too much fat is bad for your health. In order to lose fat those fat stores need to be mobilised and used as energy (or burnt). The fat is broken down and released as fatty acids into the blood stream, where it’s transported to the tissues requiring energy and it is oxidised to create ATP to fuel the tissue.

In simple terms fat cells have two receptors – alpha and beta which influence fat loss. Alpha receptors tell the cell to store fat, beta ones tell it to break it down and release it. Essentially the goal is to stimulate the beta receptors to break fat down and inhibit the alpha receptors so they’re less likely to store fat. Exercise (at certain levels) can stimulate the beta receptors through the release of adrenaline and related hormones. Hence the ‘fat burning’ zone during workouts. The alpha receptors are inhibited by diet, exercise and possibly some supplements.

So that’s great – you can do your workout, burn fat… but that won’t necessarily mean you also lose body fat. Because you STILL need to be in a negative energy balance (calorie deficit) to then actually lose body fat because otherwise the food you’re eating will just be stored as fat, replacing what’s been burnt. Using fat as a fuel and losing body fat aren’t the same thing. If you burn fat through exercise or some expensive supplement but are still eating more than your burn you won’t lose body fat. If you eat less than you burn you will definitely lose fat – irrespective of being in a ‘fat burning’ zone/workout or not because you’ll need the fuel.

So don’t focus on that ‘fat burning’ zone or workout – instead exercise for enjoyment and health, and focus on the food side of things for fat loss.

Happy Tuesday 🤗

Why you think you’re struggling with weight loss ….

Why you think you’re struggling with weight loss …. 🤔

If you’re struggling to lose weight you may look to things like your metabolism, stress levels, hormones, lack of sleep, amount of water you’re drinking etc as the reasons why you can’t achieve your goals.

It’s true that all these areas can and do have an effect and some will certainly impact on things like your appetite and ability to ‘stick’ to a calorie deficit. However it’s actually rare that these are the main reasons behind stalled progress. They do however get a lot of attention – why? Because they are much easier to accept than ‘You’re eating too much’. It’s a lot easier to focus on the idea that your metabolism or stress levels are preventing your weight loss rather than a heavy social life being the issue.

Of course things like snacking, increased portion sizes and booze can be a response to lack of sleep or stress, or hormones, but it’s far better to focus on these habits instead. Why? because they’re the direct cause, they’re tangible and easily identifiable and they’re the thing that needs to change. Rather than trying for some vague notion of ‘increasing sleep’ or ‘reducing stress’.

Obviously nutrition and weight loss can be complicated but if you try focusing on things like reduced portion sizes, fewer or lower calorie snacks, less booze you will see progress. Managing meals out or reducing them (it’s extremely hard to eat out multiple times a week and maintain a calorie deficit without some proper planning), and increasing general activity (note this isn’t just exercise sessions but general activity – walking, fidgeting, moving more!) are also things which are tangible ways to help make progress. You will probably find that despite any issues with sleep, stress, hormones etc you will be able to make progress. Certainly my clients can and have done! So if they can, so can you!

What your weight measures…

What your weight measures… 🧐

We are obsessed with the weight on the scales, when it goes up we berate ourselves, feel guilty, feel like we’ve failed.. when it goes down we congratulate ourselves, celebrate it, think we’ve succeeded. The scale going up must mean we’re getting fatter (putting on more body fat), and therefore if it goes down we must be losing fat right? And if your goal is body fat loss then scales going up signals disaster in your mind….

We need to remember that the weight on the scale measures a lot of things, and only a small portion of that is actually your body fat. It measures the amount of lean muscle you have, the amount of water in your body (hoe hydrated you are), it measures your organs, your bone mass, amy food in your digestive system etc. It simply measures your relationship to gravity at any one time.

The thing it doesn’t measure is your entire self worth! A number on the scale doesn’t define you. Whether you’ve gone up 2kg or down 2kg you’re still the same person. You are not ‘good’ or ‘bad’ depending on how that scale swings. Those swings are also totally natural and often nothing to do with body fat losses or gains.

So yes, of course, if you WANT to reduce your body fat because you want to fit into a certain clothing size, or be fitter and healthier to be around to play with your grand children etc then that’s brilliant, and that’s an awesome goal! But you haven’t failed at that, and the rest of your life, just because your weight may fluctuate on the way to that goal!

It’s worth trying to focus on goals that aren’t just a number on the scale. I often talk about using body measurements (mainly because they’re a good way to see body shape change – which correlates with decreased body fat and increased lean muscle), but how about other goals – being able to piggy back your nephew, being able to play football with your mates, being able to run for the train comfortably, reducing your blood pressure, being able to lift your suitcases in and out the car boot etc etc.

These goals are just as, in fact they’re probably more important than an arbitrary number on the scale that will fluctuate depending on how much water you drink, whether your last meal was salty, your hormones etc etc.

Tuesday Tip

Tuesday tip: Why am I burning fewer calories?

Tuesday tip: Why am I burning fewer calories? 🏃🏼‍♀️

If you wear an activity monitor / heart rate monitor / smart watch you may have noticed that over time you burn fewer calories when exercising.

These monitors measure calories burned based on your heart rate during exercise.

There are wrist and chest strap versions. The chest strap ones measure electrical impulses from heart (like an EKG). The wrist based ones use an optical sensor to measure heart rate based on blood flow. When your heart rate increases blood flow increases so the sensor uses this change to estimate heart rate. Due to this any exercise that impacts blood flow to the wrist will reduce the accuracy of the heart rate measure e.g raising arms above the head, burpees, planks etc. So there are already inaccuracies in the measure anyway.

Regardless of which method you use over time you will find you burn fewer calories than you used to. The body is designed to adapt and hardwired to be as conservative as possible with energy output (it’s an evolutionary adaptation to survive). If you stimulate it with physical stress (exercise) it’s gets better at handling that stress. The heart itself is a muscle and it strengthens. As it strengthens it can cope with more physical stress at a lower heart rate.

So whilst you may view it as a bad thing that you’re burning fewer calories in your spin class / Hiit workout etc it’s actually a fantastic measure of progress and fitness. It takes you less effort over time to perform a task that used to require much more physical effort. This should be celebrated!

It’s also a great reminder not to get too obsessed with those calorie burns. Aside from the fact that they’re not very accurate anyway, they will decrease over time and that’s a good thing! Yes you’ll burn fewer calories, but as I’ve often said you shouldn’t be eating back those calories anyway, they’re just a great measure of activity levels and progress! So if you’re exercising regularly and noticing this pattern don’t be sad – be proud! You’re getting stronger!

Happy Tuesday 🤗

Nutrition and Calorie Tips

A day of snacks…

A day of snacks… ☕️ 🍫

There are lots of strategies you can use when trying to stick to your calorie deficit to lose weight/fat. Being aware of the calories in the foods you choose to consume and swapping to lower calorie foods which you also enjoy is an obvious option. As well as the calories though it’s worth considering the quantity and volume of the food you’re choosing.

Snacking is a common problem and an easy way to extra calories to sneak in. It’s not hard to accumulate over 1000 cals of snacks in a day. A coffee when you get to work with a couple of biscuits (medium semi skimmed latte and chocolate digestives), a ‘healthy’ snack mid morning of 30g cashews and an apple, a Mars bar to give you a bit of an energy boost in the afternoon, and a small bag of kettle chips when you’re waiting for dinner. None of that will seem excessive at the time, in fact you may not even notice much if it. You can see, however, how easily it could take you over your calories for the day.

There are some easy swaps you could make that won’t impact too much on your satisfaction, still allow you to follow your preferred pattern of eating but save 500 cals. In this example you could swap the coffee to a flat white and the digestives to a couple of lotus biscuits. You could just have the apple for your ‘healthy’ snack, swap to a curly wurly to give you an afternoon boost and some pop chips pre dinner and you’ll save over 500 cals, and it’s still a lot of snacks so you won’t feel deprived.

Obviously you may decide instead to cut a few of the snacks and have the higher calorie options, but that’s where knowing the calorie content comes in! You can have whatever you want, if you can fit it into your calories, this is just another strategy to add to your toolkit to help you stick to those calories.

Enjoy 🤗
