How hungry do you need to feel?

So I didn't read the whole board, but I've gotten feelings kind of like what you described before, without the sweating. I'd be super shaky, kind of feeling like I'm ready to just collapse in a puddle and not move. I've had it happen both while dieting and not, and for me it actually seems to be related to not getting enough protein through my day. Since I started tracking I've definitely noticed my natural tendency is high carbs, low everything else. Then, as the day wears on or if I go a few hours without eating anything, I feel weak. For me it's a trigger for bingeing, because I need my blood sugar to go up and I need it to happen now. This has happened even though I've never tested positive for insulin issues.

Looking at the last couple days in your diary, you have a similar problem to what I did. Try increasing your protein, decreasing your carbs. Since I've started actively trying to get more protein in my diet, I haven't had any issues with the weak and sick feeling. It was just my body crashing hard after a blood sugar spike, because I didn't have protein to keep it going.

Also, like others said, talking to your doctor is always a good idea.

P.S. Don't drink all your calories either. it's hard to give up the pop, but you can do it. I save room in my diet for 1 pop a day (after going from 3-4 cans a day), and as time has gone on I've gotten better at drinking water. Crystal Light (lemonade flavor in particular if you're a Mt. Dew drinker - the citrus fills a similar craving for me) has been a life saver in not drinking as much pop. Lately I've even managed to cut it out of some days entirely.

This is why I log while cutting, because I can't tell from my hunger levels alone if I'm in the right sized deficit to meet my goals.

I agree with "Don't Drink Your Calories". If you simply replace your liquid calories with food (same number of calories), you're going to feel more full. The same goes with junk food/snacks. Replace those calories meat and vegetables and you're going to be less hungry.

When I started dieting, I cut out all the fast food, soda, and snacking. Stopped drinking any calories (no milk or orange juice). But in doing so, I didn't allow myself to become hungry. If it was late at night and I was hungry, I ate. I hadn't been tracking my calories but when I started, I realized that I was actually eating too LITTLE. I almost always have to figure out how to add healthy calories into my diet to avoid slowing down my metabolism (which I'd actually done). And it's pretty much all because I stopped the soda and snacks and things that don't do a very good job of making you feel full. That's the trade off.

I would make an appointment. Ignore the receptionist as they are not medically trained. Just book an appointment. I book them all the time and if its not urgent they never ask what it is for. Also your practice may have Nurse who specialises in weight loss so ask the doctor when you go.
