<human>: Could you distill the essence of the text into 1-3 sentences?

First, I should specify that I mean diet in the sense that the foods I eat comprise a diet. I'm not "on a diet" because this is a lifestyle, blah, blah, blah. 

So I was at a good point with my diet, eating only when hungry, not depriving myself. I was losing weight and never felt hungry or full. Then my dad visited and took me to restaurants and my body went out of whack. Since then I've been craving foods when I'm not hungry, hungry when I should be full. I'm out of equilibrium and I don't feel good.

More pressingly, I need to start eating low carb because a blood test at my gyno's revealed I have a high triglyceride count. It was a blow to hear that because I'm not overweight, and I thought I was eating healthy. She advised me to up my workouts from 2 to 5 times a week and eat a low carb diet. I'm getting retested in a month, and I want to take this seriously, but **the more I try to restrain myself, the more I crave junk**. 

I just went to the store and bought a pack of Reeses and a cupcake, something I NEVER do. I need to shake this habit pronto, but I'm feeling overwhelmed with school and life and I'm only working out 1-2 times a week at the moment so in general I feel like shit. 

Anyone have any advice for a girl who feels her progress slowly slipping away?
<bot>: I need to eat low carb for medical reasons, but the more I try the more I crave shit I never would have dreamed of eating before
