Keep at it, definitely! With consistency and dedication I think your goals are easily attainable. Focus on nutrition first, then healthy living and activity becomes much easier as your body functions better and your energy increases. I am a firm believer that healthy bodies are inclined more toward movement than metabolically sick bodies, and much of that dysfunction can be solved with a whole foods diet. Vegetables and meat for dinner is excellent, but don't skimp on the fat with the veggies. It helps with satiety and nutrient assimilation, not to mention is incredibly tasty
Figure out what, if any, particular sensitivities or triggers you have. Eliminate or mitigate them as needed. Then just keep at it and continue improving your health in as many ways as you can. You'll be to a healthy BMI in no time
For a smaller dress size, I concur entirely with John that body resistance exercises or heavy lifting is excellent. I managed to lose two sizes and almost no additional pounds just from building muscle. Body recomposition is excellent stuff.
I wish to the best, stay on here and stay accountable!
