gaining weight

Me! Being a bit overweight is the thing I struggle with the most. A huge part of that is yo-yo'ing between prednisone, IV nutrition from pancreatitis, and pregnancy and back and forth with all of it. My metabolism gave up a long time ago. I've found that regular exercise helps much better than trying to diet, especially since we can't eat a lot of the diet foods (I tried spinach in a smoothie once, the pain was absolutely horrendous). So I walk 5 miles every day (or I did before this pregnancy, winter, and 3 colds in one month caught up to me) and that helps. Not tons with losing weight, but with simply not gaining. I also like using the apps MyFitnessPal and MapMyRun to help count calories and track exercise.

I'm presuming you're not on steroids?

If not, then it's probably your job which is causing you to feel hungry - it sounds pretty physical if you've developed muscular arms. Unfortunately there's no easy way of dieting at the best of times; the only way is to reduce calories, which means eating less. It's not necessary to eat salads to do this. High protein is probably the best way to go: protein tends to be more filling than carbs, yet not any more calorific gram for gram.

Dunno if it appeals, but hitting the gym and toning up is another option. There are loads of gym bros on the internet who are happy to give advice on bodybuilding stuff.

You could try blending greens. A completely smooth smoothie shouldn't cause any issues and might help make you feel more full.
