I am one of those people. When I first started losing weight a year ago (currently lost 3 stone, 10lb left to go) I ate 1200 calories a day. I lost about 1lb a week until one day my weight loss just stopped. I then went up to 1400, then 1600 then started
I don't understand the science at all. I think maybe our bodies just adjust over time to the amount of calories we give it. Plus websites like Myfitnesspal don't really help as they just give most women 1200 as standard regardless of your height and how much you have to lose etc. TDEE is a much more sustainable method, I have found.
I think it also gives your body the cue that you aren't starving, so you can build some muscle at the same time as reducing body fat slightly, rather than the body automatically going for breaking down muscle as well as fat and, more importantly, it gives you the energy to still function and not feel dips in mood/energy levels that make it harder to both exercise/be active and to maintain the slightly restricted intake, thus making it sustainable emotionally and physically.
To give an example, one time I did almost zero carb/sugar, I stuck it out for about a month, lost a fair bit, but the moment I had a tiny bit of fruit, the sweetness kicked off an uncontrollable binge on anything that wasn't nailed down. But where I've had something sweet (the diet shakes I have for breakfast) every day, I've kept this up for six months - and when I was presented with a maple pecan doughnut yesterday, I could eat it, enjoy it and not feel desperate to have anything more than my usual intake today, despite being due on and definitely a bit achey from the exercise. Eating this way might be slower, but it doesn't feel like an exercise in self mortification or hatred.
Weight's gone up this week - still lower than a fortnight ago, but a) I'm due on, b) the scales say I've added more muscle and c) I'm down two back sizes and at least one cup in bra, plus my newest gym leggings are a 16 and fit perfectly.
Did get an overdue 'please book your check up for Diabetes and everything else because you're old and fat' letter from the GP this morning. It'll be interesting to see the practice nurse who told me I just had to 'give up eating all those lovely pies, cakes, biscuits and chocolate that we all love every day' that I didn't
bleeping eat in the first place with my resting HR at 63 and hopefully my already very good BP improved even further. We'll also see whether her dire warnings of my (normal) blood sugar level meaning I was guaranteed to be diabetic by January were accurate.
