I actually did and wrote a long post that then disappeared and I couldn't be arsed to rewrite. Ill try again.
Look Im not an expert and some people think I should have no say cos I wasnt technically overweight to begin with. All this is just my opinion, and I could be talking complete bollox (wouldn't be the first time) but I will give it anyway.
Firstly, to whoever said I lack credibility cos I wasnt overweight anyway, well Im not selling the stuff so I dont really care - Im not trying to persuade people Im actually trying to get people to persuade me cos I dont get it. Also, I think BMI is a bit of nonsense. The fact you cant take it at BMI 25 or 27 Im not sure, I think it odd because honestly most people look and feel better at BMI 20/21 (not all - but most I think). At 25 I have all the chins and wobbly bits, at 23 still a bit (I can achieve this naturally but its still a ballache) at 21 I feel and look great (and I cannot achieve this naturally without being uber depressed or having had a massive stomach flu or something). So thats my opinion on that, and the stats and even on here seems to show that no matter how big someone started out at, they want to get to about 21 and then maintain that. So why is the MJ cut off 25? Seems daft to me. Yes I did lie - its super easy.
As for healthy eating here is probably where I will lose people but here goes. I think that no one can decide what that even means - not even nutritional experts and doctors. Vegan, carnivore, keto, gluten-free, veggie, fruitarian. You have people saying protein is everything, that's the new obsession have you noticed that? No one used to talk about protein like they do now - it used to be fibre. Its the latest marketing ploy and now everything is labelled 'high protein'. Some experts think fruit is the devil, some think its life! Some think red meat is awful, some its the most nutrient dense thing you can have. High fat/low carb, low fat/high carb, leafy greens are essential for health and lots of - no leafy greens because they are toxic. We shouldn't be eating grains/legumes because they get stuck in gut - we should because they are just soooo good for us! If you take the burger analogy at some point in history every single part of the burger - bun, meat, salad, sauce, - has been demonised at some point. So I take the whole idea of 'healthy diet' with a massive pinch of salt (pardon the pun). I dont think there is any such thing, I think that it depends on the person, it depends on what they want at that time, and I think people should try harder to listen to their bodies and what it wants rather than being drowned out by food noise from childhood and being told certain food is 'bad' and 'good' and to clear our plates.
Also, im not convinced by the concept that if we dont eat 1000 calories a day with certain nutrients in the food daily we are going to get long-term sick. I say this because of all the evidence that fasting has such brilliant long-term outcomes and that we were designed to eat every three days - boom and bust. And im talking 30 day fasts. People have had their crohns, diabetes and other conditions reduced or cured by it, so I think we as humans think we are going to drop dead or be crippled by illness if we dont eat xyz for a while and I just dont buy it.
So in response to this - surely you can see that eating a healthy and nutritious diet is important for people who are in significant calorie deficit for years (in some cases)? It's genuinely hard to get the correct nutrition on 1000 cals a day and not doing so over years is really bad for you, obviously!
I dont think a 'healthy and nutritious diet' can be defined, and no i dont think calories of 1000 a day would be a problem for years to come for someone, no. Not at all.
