Very Low Calorie Diet ..any experiences?

Speaking as someone who obtained an eating disorder that way, I would advise against it.

You could say that it's not just anyone who gets an eating disorder and the person who ends up that way has to already have a lot going on for them already, but to have that much importance and emphasis on cutting back to such an extreme I would already argue that your in a very vulnerable position right now and putting yourself on such an extreme diet would put you at risk, not just physically
-(your heart being the number one organ affected by this and if you're already obese it's very likely your heart isn't in great condition as it is- sorry)
-With calcium levels in your bones (once your body gets rid of all it's food energy it leeches nutrients from your bones to sustain itself; calcium keeps your bones strong, without it you will end up with brittle bones)
-Muscle wastage (again; a very useful energy source for your body once it has run out of food)
-Also (but not finally- there are many other very possible problems); huge cravings for carb rich (ie high sugar) foods which can lead to all sorts of problems if you end up eating a high sugar diet. (Google the dangers of a high sugar diet if you need more on that; many sites have info on it).


You mention very little energy; this is your body trying to conserve what it has. It's slowing down and your metabolism is falling. It means your body can run on even less to keep you functioning. It wont suddenly switch back to normal when you hit your goal weight, it will if you move more and eat more (even just eating more can help short term to give you a boost) but it is a big problem and can result in metabolic issues. It's a sign you're body is struggling at the moment.

And that's if you manage to catch yourself before the damage has been done- many people are so strong minded they don't realise these physical problems have crept in until the affects are quite obvious. Some even die this way. I know, I've met them.

Look; don't just take this all from me. I know I've been there but I'm just one person and you don't know me from anyone else on the street.
Can I ask that you speak to your GP and talk about your plans before you start anything? It is such an extreme and would put your body under a lot of pressure and if your GP is aware of any underlying issues you may not be, they can offer well qualified advice or at least shove you in the right direction.

No GP would recommend a diet of 500 calories a day. You need more than that for yr body to just carry out its normal functions, let alone provide extra to give you energy. Being overweight, you actually expend more calories from cell regeneration and breathing than a thin person, so your calorific starting point for weightloss, wld be way above 500 calories. A very restrictive diet wld start around 1000 calories a day, so half that is madness.

I wld be back to the GP and getting a referral to a dietician/nutritionalist, who knows what they are talking about

I don't know if this will be of help to you Mumcoach, but what I used to tell myself was 'I know exactly what that chocolate biscuit/bag of crisps/roast dinner tastes like and therefore I don't need to eat it. One day I will have it again, but not at the moment' then go and find something else to do.

Accept the irony in the term 'meal replacement' and just view it as 'fuel'

Thank you all for your opinions. I have spoken with the gp before starting this and he gave me the green light. It is very hard going but all other attempts at weight loss have failed for me even seeing a dietician didn't help.

I have to say this morning I'm struggling to even move. I find it hard preparing food for everyone else knowing I can't have any but hopefully the results will be worth it. The tiredness is extreme, yesterday I slept for 15 hours but today I'm finding myself alot less hungry, so hopefully I'm past the worst!
I just need to resist the urge to weigh myself every day!

The reason your tired is because your body is shutting down because it is trying to conserve calories to keep you alive- you need a base amount of around 1200kcals just to keep your heart beating. If you want more info on this, look for information on Basal Calorie Requirements. This is what scientists have worked out your body will need just to keep you breathing unassisted and your heart beating unassisted when in a bed and in a warm room.


Without keeping to this your body will begin to eat itself and it does so in a particular order; it picks what costs you the most energy first. Muscles cost your body a lot of calories to use. Your heart is a muscle and your body will take from these muscles to keep you going as it is harder work for it to extract your energy from body fat.


Please get some medical advice on this. You could be causing yourself damage. I can understand it would feel like the last thing you want to do to eat more but that is what your body needs to function at the moment- just a basic amount. At least get some medical advice on this because your experiencing symptoms right now which do need medical advice which do need professional support.


This isn't my opinion by the way- it is medical fact. I have had a lot of experience in this area and I have had to learn more about this area in particular in order to help myself out. I have not gathered this as an opinion but as proven-by-science and experience (of others as well as myself).
