This is an interesting question, for sure. What does it mean ... to reach goal?
I started at around 300 pounds and my goal was 200 (or whatever amount it takes to loose my moobs). I thought that was kind of pie-in-the-sky, but why not? Well, I started exercising a lot and was pretty anal about following the sleeve rules and hit 200 after about 5 months. I still had some belly fat, so I reset my goal to 190. That number came and went after a few more months (moobs gone, btw). So, I wondered, too, what was going to be my final weight? I eat whatever I feel like, but know that I eat pretty well. I am not a saint ... I had a bowl of Reese's PB ice cream tonight (1/2 cup).
So, what is life like? I eat whatever I want. I don't worry about my weight at all. I did weigh myself the other day and I clocked in at 175. I figure my body will find the weight it is supposed to be. I don't count my calories or my carbs. I didn't get sleeved to be a slave to a diet. Just the opposite, actually.
So, my suggestion is to not set a target that you feel you have to reach and if you don't, you're a failure. Let's not beat ourselves up. Just do the best you can to follow the guidelines and find the foods that work for you. Find an exercise routine that works for you and do it ... a lot.
You're body will find the place it needs to be and you will be heathier for it ... physically and mentally.
