Does exercising on an empty stomach maximize fat burning?

I have recently learned that in order to burn fat as a fuel, your body requires carbohydrate. Up until this point I had been doing cardio training first thing in the morning on an empty stomach, as I had read that this is optimum for fat burning. However, now I have a small carbohydrate snack before I train in order to prevent my body using lean muscle tissue as a fuel. Today I have again read in another book that training on an empty stomach first thing in the morning burns the most fat. I am a little confused over the best thing to do! I train with weights twice a week and do cardio three times per week. I do want to maintain my lean muscle, but am looking to reduce my body fat.


Is there a connection between cortisol, depression, and weight loss?

I recently went to my doctor because I've been unable to lose weight. I've been on a successful diet, accompanied with a reasonable exercise plan, but I've seen no real results. A series of tests were run — I've got optimum blood pressure, low cholesterol, and I am not diabetic. But, when my cortisol levels were checked — they were very high. The doctor suspected there was a possibility that I might have Cushings' Syndrome — but another test was run and that came up negative.

I was doing research on the internet, and I found that there was a link between excessive cortisol and depression. I was diagnosed with clinical depression when I was 12 (I am now 21). And I am currently untreated. What is the link between cortisol levels and depression? Are excessive cortisol levels a physical manifestation of depression? Or does an excess of cortisol for some other reason cause depression? Does an excessive amount of cortisol cause weight gain, or in my case prohibit weight loss? And if there is a connection — will treatment for my clinical depression (in the form of prescription pills) help me?

I've been unable to find answers anywhere, or at least a good source to tell me to stop worrying — any help would be appreciated.


Is my vegetarian diet making me feel tired?

I am a vegetarian and frequently feel like it takes a long time to "wake up" in the morning and some days I feel like I never quite get there. I can't help but think this may be diet related. I went to a doctor for a test for anemia which was negative and I always try to get a good nights' sleep (six to eight hours). In the past I have tried to gain weight and failed miserably. I remain a little underweight but get a good deal of exercise each day. Any ideas?


Why am I depressed as I navigate my sexuality?

Thank you for everything, and it is being appreciated by thousands. I have read all your advice to others and have learned a lot. However, I have a problem that I do not know how to handle. It started when I decided to turn myself around from being bisexual to straight (nobody knew what I was, except my best friend, who is also bisexual). I now have a big hole inside me that is being filled by the dark things of life (such as hatred). I had good qualities, such as a great personality, being open-minded, and I would rather go through life without it than turn back to the "bad" habits (please do not get me wrong, I will never judge gays for I have been close to being one). Please help me to fill the hole with life, to get back or improve on my qualities, and to gain the knowledge to approach and attract someone of the opposite sex. And one last thing, do you think it is wise to let my future girlfriend know what I used to be?
