I don't seem to be getting any smaller?

Are you really 18?

Your diary is blank. How do you track your calories?

This. It's very hard to give any sort of useful advice if you don't provide the most important information component to weight loss.

No one loses 28lbs and doesn't get smaller. I'm not seeing any real problem here? Progress is progress, keep up the good work

You may not have hit your weight loss goal yet, but don't forget that plenty of that fat has become muscle!

I realize that you're trying to encourage the OP, but fat cannot become muscle. You can lose fat by eating at a deficit, or you can gain muscle by eating at a surplus. You can recomp, which means you VERY slowly build muscle and lose fat at the same time by eating at maintenance, getting enough protein, and lifting weights. But you can't change fat into muscle, because they're completely different kinds of tissue.

I don't think you understand that muscle and fat can't turn into the other.

28lb. loss IS you getting smaller. Pictures and food diary info would be helpful.

I've struggled with my weight my entire life and this year I've decided that I'm going to try to lose at least 50 lbs in a year. Unfortunately that didn't happen I lost 28 lbs which makes absolutely no sense since I had started on a vegan diet this year and started working out in an actual gym. I eat on average about 1200 calories per day. I walk about 40 minutes at 2.8 on a treadmill and using the weight machines. I have practically doubled the amount of activity I do during the week.

I've also have noticed that my muscles have become more defined but I still have lots of fat. My parents have commented on the fact that I look healthier and I have been able to be more active.

My family has always struggled with their weight and it seems that I'm no different. Is there anything that I might be missing or overlooking that might be preventing me from further losing anymore weight?

you lose weight on a deficit, whether you eat vegan or not (in fact there are quite a lot of chubby vegans on this website). When you say you eat on average about 1200 calories, are you tracking this elsewhere? If so, how accurate is your tracking? Are you weighing everything and only measuring the liquids?

50lbs means 1 lbs a week i.e. a deficit of 500 calories a day, since you lost 28, I go with you are actually having a 250 calorie deficit a day. That's not a terrible deficit or a terrible result. I do think however you are estimating your calories is not accurate and you are undercounting. Now that is not a bad thing, because, even without your other stats, I somehow doubt you really should be eating 1200 calories. One issue would be if you lose all your weight on 1200 calories as soon as you go back to eating like the rest of your family, you are likely to gain it all back. It might be worth, if your whole family struggles with weight, to look at portion sizes and calorie values of popular family foods in general. Eating healthy doesn't have to mean eating vegan or vegetarian or low carb or low fat or whatever else the popular opinion seems to tout as the best thing ever.

Don't short change yourself--28 pounds is quite the accomplishment! You are being too tough on yourself. Your goal was 50 lbs--you lost 28. You could have gained 28 pounds, but because of your hard work you lost 28 pounds. Chin up and keep going.
