Why do I get flushed and tired after eating lunch?

I find that when I eat lunch I can feel myself instantly get tired as if a wave passes through me. My face gets a feeling of being sweaty and flushed. Coffee and copious amounts of water help counteract this. Also, it doesn't happen every day with every meal. Very small amounts of food don't cause this. It's as if I eat above a small threshold, then it happens. It makes it hard to work. A short nap would be perfect (but not possible). Is this something to be worried about?


What are the effects of calorie counting and intermittent fasting?

1) I've started counting calories in order to lose weight, and I've lost ten pounds in six months, so I'm positive that counting calories works. Recently I've started to eat one big meal (about 1400 calories) a day. Is this healthy? Will I continue to lose weight?

2) During the day, I keep a strict paleo diet and end eating at 10PM and Begin eating at 12 PM the next day. Around 10:30 AM the next day, I do full a body weight training session and begin eating at 12 PM. Basically, I only drink water during my fast or keep calories to a five calorie maximum. After the fast, I eat whatever I want (paleo that is). I'm trying to get my body to use excess fat as energy, therefore causing me to lose body fat and gain muscle faster. I feel great and I have witnessed fast results, (increased strength and leanness) within a month and half of intermittent fasting. My question is do you think intermittent fasting is unsafe? Or just a new an effective way to see increased health?


Do diet sodas spike insulin levels?

I have heard that the main reason why diet drinks, like a diet soda, can be bad on a diet, is that it can spike insulin levels and then your body expects sugar that it does not get. I have taken to the habit of only occasionally having diet drinks with meals, so that any increase in insulin is actually met with food in my system. My question is whether or not this is a good/workable strategy, or whether a diet soda is a diet soda no matter when you drink it and is therefore always a bad idea. Thank you for your time.


Is stress causing my chest pain?

1) For the past year now, I have been getting sharp chest pains. Sometimes it feels like I am about to have a heart attack. I find it painful to breathe for the couple of seconds that it happens. The sharp pains occur mostly in the lung/heart area. However, I have also felt them in the lower chest area as well. I don't know what is causing this.

Also, it occurs most frequently during the school year. I should also note that during the school year, I tend to eat greasy fatty foods. However, I had my cholesterol level checked (95) which is low. These pains come any time of day, while I am sleeping, walking, sitting, etc. I am 21-year-old female, if that helps.

By the way, I have a doctor's appointment back home later this month. But I want to have an idea why this happening. Others mentioned to me things about stress, something about a dog's heart, and I was even thinking that it might be cancer.

2) I've recently been experiencing chest pains in the sternum area. Although I don't believe it is related to heart trouble, I think the pain is originating from the bones or muscles attached to the sternum. I have seen doctors but most are clueless as to where the pain may be specifically originating. An interesting side is that during times of stress, the pain is more severe and concentrated at specific points along the sternum. One hypothesis is that the pain may be related to an injured sterno-manubrial joint. If indeed this is the case, what therapy is available to a poor, uninsured student? My mental health is being affected since my once pumped-up, rock hard body is slowly atrophying since I can't lift weights without extreme pain. I'm depressed because the size of my chest is now smaller. What do I do? What's wrong with me?
