Hello! I'm so glad you write in with updates and questions. I admire you greatly for losing weight and keeping it off, yet I also hear how it's frustrating not to reach your goal despite the wonderful changes you've made. I have to tell you something you may not want to hear: to lose additional weight, it sounds like you need to go back to being vigilant about measuring and sticking to the prescribed portion sizes on phase III and cutting out most of the "extras" (you could try having 2 "extras" a week, but that's it). You have shared that your current exercise routine works for you in terms of what you're doing, the intensity, and the duration, and if that's the case, I'll just say I'm thrilled you've found a routine that you can stick with and that works for you. If you were able to increase any form of interval, build in more targeted / intense strength training, or mix up your activities that could help, but it might be at the risk of injury of feeling like it doesn't fit into your life and therefore you wouldn't do it.
Here are some suggestions:
1. For dinner (or even lunch) once a week, have a "dessert" meal consuming only treats that add up to 400 or 500 calories
2. Try switching up the foods you eat building in even more whole grains, add foods you don't normallyy eat (maybe it's quinoa, millet, steel cut oats, exotic vegetables you find in the Latin American and Asian sections of the produce department), stick to watery vegetables such as lettuce varieties, green peppers, cucumbers, celery, zucchini, etc. rather than carrots, orange peppers, tomatoes, pea pods, etc. to cut down on calories, and making sure all of your protein is very lean. Maybe you do better without refined flours, yeast, wheat, dairy, and soy? You never know and it's fun to experiment with new foods and recipes.
Sometimes little changes can make a difference - think about what it is about losing that remaining weight that gets you feeling good about yourself (feeling "lighter", wearing different clothes or feeling more comfortable in your existing clothes, feeling like you're healthier at a lower weight or more energetic, imagining yourself looking more trim, etc.) and keep that in mind as you do what it takes to get there.
