Nutrition Advice Needed

No grains at all?
Not even some steel cut oatmeal?
Complex carbohydrates would help level out your low blood sugar issues.
For cravings, I tend to get them when I'm not eating enough protein.
Maybe some beans or hummus or tofu might help you out with getting some more protein.
Also, although exercise is great for you in very many ways, too much can ramp up your hunger big time and make inflammation worse.
An important partner to exercise is rest so your tissues and muscles can rebuild and heal.

Carbs are important as long as they are the right ones. I don't think I would want to 100% grain free myself.

Even on a low carb diet they recommend you have a certain amount of carbs per day. I suggest you go to the public library and look at nutrition books. Once you start over-viewing them you'll start to see some diet regimen that seems to be what you want.

My FIL does low carb for his blood sugars and heart issues and only does around 40 carbs per day I think. He eats bacon and eggs for breakfast every morning. Fish, meat, veggies, all sorts of stuff. His heart is healthier than it's ever been and his blood sugars went from being borderline to low/normal. His cardiologist has even recommended some of his other patients go on this diet.

All in all you are the one that needs to go look at a bunch of books. I find that if I go to the library and get a table back towards the section I'm looking at then pile the books on. I sit and look at the forwards, some of the recipes in the cooking section, see if it's food that appeals to me, see if the philosphy works in my mind.

Then I start compiling recipes and thoughts. The books that have the most information on that topic are the ones I check out.

Elimination diets are common now but food science says that they are pointless. It makes no sense to take out of our diets those things which people have eaten for generations, even centuries! Taking out processed foods and refined sugars is fine, but taking out everything? You may well be going through detox but it's insane to think it should take months! You've made a drastic change and it's putting way too much stress on your body.

By adding the right BALANCE of nutrients in a highly absorbable form, you can easily process the nutrients you take in. You're light-headed, you have migraines, inflammation. It makes much more sense to supplement in a way that gives you energy and with a very gentle detox over time which will remove toxins from your body without exhausting your body, which is what's going on now.

There is fantastic research on the anti-inflammatory action of a natural peptide. There are also some very simple steps you can take to stabilize your blood sugar, based on solid clinical studies (none of them by pharmaceutical companies - this is a non-drug approach). You can detox gently if that's needed, increase your energy, and eliminate the migraines and joint pain. I've been working for years in this field.

You definitely need more energy and stable sugar levels if you're going to work out at the level you say, and you should be able to.

Again, elimination of entire food groups makes no sense - first of all, people can't stick to it, and secondly, it's just not necessary. I know there are dietitians who have their own philosophy on this, but it has not been borne out by 25 years of food science. It's a new trend that will disappear as fast as it came in.

Happy to give more info. We do phone consults all the time and you really don't need to be paying for all those visits! Especially when you aren't getting results, and you're unhappy.

You don't say why you are adopting this restricted diet. Are you very overweight?

You work out a lot, so that's not an issue. Unless you are gluten sensitive, I don't understand why you need to cut out whole grains.

I don't know why the diet you are currently on is considered a "detox" diet, you are basically just eating healthily (although I think some grains would be good for you), so I think it's total b.s. that you are "detoxing," and will continue to do so for months. That makes absolutely no scientific sense.

Are you eating enough calories? With the amount of working out you are doing, I'm not sure how you could be consuming enough calories with some veggies, nuts, olive oil, yogurt and fish.

Also, losing 3.6 lbs. in one week is the sign of pretty severe calorie restriction, unless you started out extremely overweight. I think your current diet might be too restrictive. Cut out processed foods and added sugar -- you can't go wrong with that, but vary your diet a little more.

You need to include your weight in your question.

You are 45 and this could be in part Perimenopausal symtoms.. example the headaches although true could be partly from detoxing... they could also be because of declining levels of Progesterone.. (in particular, right before your period, when your Progesterone drops off) this can trigger a headache.. and at 45, you aren't going crazy with regard to those sugar cravings..... by 45, Estrogen levels have also dropped off, which might also mean you are at times Progesterone dominant, not that you produce more, but rather in relation to the Estrogen... which when that's the case, yes, you can become more insulin resistant....
what fun right? :):) I've trained with trainers before and not many of them completely understand that EVERY woman is different and every age group requires a different type of training.... It wasn't until I read "Screaming to be Heard" by Dr. Elizabeth Vliet, that I began to understand why IF I was exercising so damn much and eating healthily, why wasn't I losing weight.. FINALLY... a book, a doctor who spells it out..
check it out.. it was so helpful ... the book has so much good info in it.. and why doctors and even personal trainers aren't better education their clients with regard to the role hormones play is beyond me..
BEFORE you spend more money on a doctor/dietician or personal trainer.. try and get the book from your library..... It talks about all the things you mentioned above, joint pain, cravings... headaches..
I think you'll like it..

good luck

I am no doc, but I believe everything in moderation is the way to go.

It sounds to me like you need more protein in your diet. I try to eat mostly vegetarian and I love my Non-GMO protein shakes with fruit. Have you tried something like that? Mine are perfect glycemic index. It will help you with the sugar cravings, help you feel sated. As for inflammation. Sugar is bad, but I still treat myself in small amounts usually on the weekends. If a piece of pie is being served....... I allow myself a very small piece, then stop. The problem with sugar is you want more once you start. Taking a good dose of omega-3's (fish oil) daily will help reduce inflammation as well.
