Headache, Dizzy, Anxiety... from reducing calories??

That sounds like me after a few days without my morning coffee. I get the caffeine withdraw symptoms. I would think the alcohol might have something to do with it if you had a problem but if it's easily been cut from your diet I would it could be something else. Has your blood sugar level ever been tested. My hubby has issues if he doesn't have sweets for a few days. We keep regular coke and candy bars in the house for him when he starts feeling dizzy after a lack of sugar in his diet.

Most likely, yes. I started out with my calories too low, felt fine for the first few days, and then BAM, starving and grouchy. I had already assumed my calorie goal was too low but wanted to see what happened since at the start I felt great. I upped my calories by 300 that day and have felt better ever since, it's been over a month now, no more issues and the weight is working its way off.

Of course there's a simple way to find out, eat a bit more for a few days and see if you feel better.

It doesn't sound like you are eating enough. Your symptoms, if they've only started happening since your diet change, make it seem like your body is under a huge amount of stress. Your body is telling you something you are doing is wrong. Generally, a good rule of thumb is to calculate your BMR (the amount of calories your body needs to function daily) and never go below that. Then, calculate your TDEE (how many calories you generally burn in a day) and subtract 20%. That's a closer number for safe weight loss, and it will change as you lose weight.

Also, while low carb diets are recommended for some, you need to do research before cutting bread completely out of your diet. My trainer told me that ultra-low carb diets can really mess with your hormones and will make you seriously sick if not followed properly. Carbs aren't evil! You need them too, just in moderation like everything else.

sounds like a blood sugar crash. My daughter is insulin resistant. When she gets this way one TBSP of peanut butter or OJ will raise the sugar levels back up.

I'm eating mostly lean meats, veggies, some fruits, and minimal dairy. I am 5'5" and weigh 233. 30 years old. I haven't started exercising just yet. I do eat flavored fat free yogurt every morning which I'm sure has sugar in it. Aside from that, I'm steering clear of sugars.

Maybe staying clear of simple sugars is your problem, because it seems you are/were used to them. You are not used to eating low sugar, low processed carbs and your system complains because of withdrawal. I would recommend that you don't go cold turkey, but do the change over a week to ten days. You will feel better and that might motivate you more to count calories and to exercise. Of course you can also push through the problem since you already have started the withdrawal process.....I think the choice is yours.

Good Luck !

This happened to meat the beginning of my weight loss when I did a course of meal replacement shakes (Optifast).
I was eating a very low cal diet (under medical supervision) and found I had headaches, dizziness(from low blood pressure) and I also got REALLY cranky! Thankfully this was only temporary and once my calorie intake went up, I felt heaps better.
Try this website for a really good selection of calculators to determine the best calorie intake for your height/weight/body fat:

You will probably find that 1200 cal might be a bit too low.

With yogurt really read the ingredients. I am huge fan of Chobani. Greek yogurt is higher in protein so it will give you energy longer. A lot of yogurts contain ingredients like high fructose corn syrup, corn startch:explode: and gelatin instead of the live cultures that make eating yogurt so beneficial.

I had the same experience after a week. I added up my calories to 1500 and I feel fine.
Headache is probably because you don't drink enough.

Happened to me too. Went to the doctor and found out my blood sugar reached almost the lowest level acceptable. So i now eat fruits rich in sugar or a small candy. Nectar gets into the blood fast so eating something like a nectarine is a solution.

Also, eating less than your BMR can cause your organs to stop working properly. If your kidneys don't work well a lot of bad things could happen (i know from experience). Also, carbs are not that bad. Increase to at least 1400 cals i would say and eat more carbs.

I think you might be eating too little. I weigh 235 lbs and eat 2200 calories/day. Did you calculate your TDEE and BMR? There's a thread called "In place of a roadmap" that explains very well how to get those numbers and what to do with them. I suggest you give it a look. Good luck!

May I ask why you are eating so few calories??? At your age,height and weight your BMR is 1760 calories..... How are you figuring your caloric intake needs???

So glad you posted this I was wondering the same thing today except I didn't drink or have a lot of caffeine I just started working out more. I feel like I eat enough food like 1600ish cals but I am burning 600-700 and I didn't think about it today that that s leaving me with so little to run on. Im having trouble focusing and feel almost dizzy but no quite it is hard to describe. I eat bread though also oatmeal almost every morning.
