But it’s not as simple as that. Your body will learn to lay down fat when it isn’t getting enough to eat so that it keeps some reserves. This is how restrictive eating changes your BMR, so your resting body doesn’t use as many calories. That’s why people who have dieted all their lives only have to look at a piece of cake and they put on weight.
Muscle burns more energy than fat, so the solution isn’t to calorie count but to increase muscle by weight training, reduce sugar spikes which disrupt the body’s natural metabolism by eating more protein and less sugar and diversify the gut with lots of different plant foods. The result of this is that you get fewer cravings and feel more full, so you build a way of eating that allows your body to burn it off.[/quote]
I’m not sure that this is accurate in some ways and some of this stuff can be unhelpful for people trying to lose weight or learning how to adapt their diets
Your body just does what it does functionally, it doesn’t fundamentally change itself depending on what you are eating or doing in the way you describe that it ‘learns’ something new. It’s burning energy at different rates depending on what you put in it and what energy you burn. There is also genetics and hormones to factor in etc. you are telling it what to do. If you stop doing it, it will stop doing it. your body wants to burn carbs first while you exercise. If you eat little or no carbs, it has no choice but to burn the fat.
Everyone has muscles all over their body not only thin or fit people. Hence getting active helps you burn more energy. Your body burns energy just from being alive. You aren’t just burning ‘fat’ using these new improved muscles you are burning energy which includes carbs and fat stores.
If you get more active and eat in a calorie deficit you will lose body weight. But you do not have to build a lot of additional muscles to burn your fat. Many people do low intensity stuff like walking and it’s enough to get them to either lose weight or maintain it.
anyone selling you specific ‘fat burning’ things like PT sessions is going to probably try to get you to do some kind of HIIT, which might find horrific and uncomfortable because you are unconditioned and heavier than them and you may well hurt yourself or fall into patterns of eating back all your calories (which your Fitbit has helpfully massively over estimated). You will burn off fat (and carb stores) doing HIIT a lot faster so if you want a quick result, this is what a lot of people do. But I am not sure it’s sustainable unless they learn to love doing HIIT and people give up
You will change your metabolism by being leaner and more active, you will have a lower BMR than you did before.
But the key to it all is changing your mindset and attitude towards food and exercise. Making better choices, portion control, moderation, changes to your level of activity are more realistic and sustainable. If you find exercising that you love, then do it but if there isn’t, you aren’t a failure. It’s so easy to feel like a failure when you see all the gym wear toned people who get up at 5am but that life isn’t for us all and we have to find what does work. The idea of living on 1500 forever sucks a bit for me but it also sucks being fat so I need to decide what one sucks less
