How can I eat healthy when my partner doesn't?

I am very interested in nutrition and enjoy eating a well-balanced diet because it makes me feel healthier, happier and more energized. I also have a terrible sweet tooth, which I combat by simply not buying junk food when I shop for groceries (although I will indulge on rare occasions). This strategy has worked for me very well — up until now.

I am living with my boyfriend who, despite even his doctor's warnings, has a rather unhealthy diet. In an effort to nudge him in a better direction, I have offered to cook most of our meals at home myself, but with little success. He's a picky eater and often declines the meals I prepare in favor of pizza or Chinese take-out instead. I would just give up and let him clog his arteries, but his unhealthy habits are starting to affect me. When he brings home tacos, or especially bags of candy, I inevitably eat them also. I am a decent cook, but a greasy pizza always tastes better. If I can't change his habits, how do I at least keep him from changing mine?


Can I get over my food aversions?

I have a very strong aversion to certain food textures such as potato (mashed, chipped, roasted, etc.), that causes me to gag violently. I am 22 years old and have a BMI of 16 which I blame in part to my very unbalanced diet. I am constantly lethargic but am eating three good portion meals a day. I was wondering if there was a way to get over this sensitivity as I am eating cereal without milk every morning, plain pasta for lunch and a pizza for dinner every day, I am looking to be a lot healthier with my life.


What can I do if I have no time for a social life?

I am a 22-year-old male grad student, now starting my second semester at in graduate school. I have been doing very well academically, but my studies and my work-study job leave me absolutely no time for a social life! I have not been on a date since I got here; though I meet a lot of interesting people, and am in the habit of collecting their phone numbers. However, I can never seem to find any time to spend with them. Sometimes this really depresses me. I have noticed that I have lately been smoking much more heavily than I used to.
