So firstly that’s great progress from 415, good start and I’m sure you feel noticeably better. You’re working on the CICO model and thats great, you’re focusing on the right things. Looks like you have the CI part of CICO nailed, assuming you are logging your food honestly and not sneaking in extra treats, where you are falling down though is in the following logic:
You believe that this wrist band is somehow calculating all of the thousands of complex metabolic processes happening within your body, as well as your nature and the nature of the physical activity you are doing?
This band might know how many steps you take in a day and is probably measuring your heart rate elevation over time and, using those factors EXCLUSIVELY is ESTIMATING your calorie expenditure.
The bottom line is, you’re eating 2500-3500 (ish) and you are maintaining your current bodyweight. Therefore that is how many calories a day you are burning. There is no argument to be made there, if you eat 3,000 on average long term, and weight does not move long term, 3,000 is how many calories you are burning, on average, long term.
I also don’t buy for a second that you are in ‘starvation mode’ at 3,000 calories. Your body has more than enough calories for its basic underlying functions, no survival instincts are required at this point.
Since it looks like you are already working out pretty hard with some cardio, and in my experience there are definitiely diminishing and negative returns to adding more cardio to achieve weight loss, the bottom line and boring answer is that to continue weight loss, you need to do exactly what you did to lose weight in the first place, the same thing everyone else has to do to continue stalled weight loss, you need to get more strict on your diet.
You need to eat slightly fewer calories daily, and I would seriously recommend getting some vegetables, or at least some fruit in there. Your diet is literally brown exclusively and I don’t see that there is any way that you aren’t micro nutrient deficient across the board.
I’m not going to make specific reccomendations, mostly because there are hundreds of ways you can improve your diet or effect the reduction in calories. I think whats important is that you understand that is what is required and find a way to do that which is sustainable for you. You managed it once so I believe you have the mindset to do so successfully.
I would like to reiterate my first point, that you’ve lost 80lb and that’s awesome, probably lifechanging to a degree. Losing the next 80lbs will be harder, probably slower BUT even more rewarding. Physiologically and psychologically.
