I don't think it's nuts. I am no doctor but I have a theory, which is basically as simple as positive versus negative thinking and energy. I absolutely believe eating foods you like, especially if they are naturally healthy, can help with depression. I think a reason many people become overweight is they seek something which provides something positive, like tasty foods, to alleviate depression. Unfortunately, they often choose junk food, which I don't recommend as it can spike your energy level, then bring you back down. Eating healthy can provide a much nicer energy curve, which I think is very helpful. Like others have said, I also believe exercise can help. This is because you take on a positive task (betterment of your health) and feel good for completing that task, in addition to feeling better physically. Here again is something positive which I believe offsets negative energy/thoughts. Chemicals within the body may also play a role, but again, I'm no doctor. I do, however, strongly feel that positive thinking and acts are very helpful. On the other hand, negative thoughts can spiral downward and become even more of a problem, so dwelling on negative thoughts should be avoided.
