If you continue eating Whole30 style, making your meals match the meal template, you will continue to improve your health, and you will almost certainly also lose weight as you get healthier, although it may not be as fast as you would like. However, losing weight slowly while eating in a way that is sustainable means you won't yo-yo, losing and gaining and losing over and over again.
Losing a pound a week is not bad. Keep doing that and in a year, you'll have lost 50 lbs. Focus on the other improvements you've seen. List them somewhere -- actually write them down -- and when you feel discouraged, refer back to your list. Add to the list over time, if you experience new improvements. If you have trouble getting started, here's a handy checklist you can print off and mark the ones you've experienced.
Remember that the more time you've spent dieting, gaining and losing weight, restricting your calories, the longer it is going to take to really heal from that. I know that it's frustrating, and I know that you want to lose weight as quickly as possible, but think about your experiences with other diets. You've lost weight on them, sure, but it sounds like you weren't able to maintain that weight loss -- therefore they didn't really work. A successful diet not only helps you lose the weight initially, it helps you maintain a healthy weight and a healthy lifestyle. Try something new. Ditch the scale, focus on non-scale victories and on eating healthy foods that will nourish your body and make you healthier.
