Well I log everything I eat on Fitday, I am 5ft 3in and aged 39. I started at 17 stone
and am now 11 but would like to get down to 10. By breaks I mean I have taken the odd week off from time to time but find I immediately put on myabe 5 - 6 lbs. My last break was a weekend off about 3 weeks ago. Sometimes I feel like I am chasing my tail. Another thing that has hampered my progress is a thyroid problem which was diagnosed a couple of years ago but seems to have stabilised with medication over the last 6 months. Thanks for all your help and advice Steve
Assuming your metabolic rate isn't drastically skewed from the thyroid issue, I really recommend upping your cals to get things back on track in terms of metabolic rate.
If you are barely losing weight by consistently eating 1000 calories per day, the various survival adaptations have really kicked in, in response to your either prolonged or extreme dieting.
By eating more, you probably won't lose weight, even though there is a chance. You shouldn't view it as a weight loss tool. Instead, it is a fix to an issue that is currently slowing, if not hindering, your current weight loss progress. Follow me?
Right now you are 150ish lbs. I would like to see you work your way up to 2000ish calories over time. I certainly don't expect you jump up to it immediately. You have to do it on a slow consistent basis to let your metabolism keep up with the increase in caloric intake.
Suppose you are eating 1200 calories per day now.
I would start next week with the following:
Week 1 - 1400
Week 2 - 1650
Week 3 - 1900
This is simply an example. Depending on your body's response, you might want increase calories at 2 week intervals instead of 1 week intervals.
It should be apparent that tracking weight and measurements during this time period is crucial. This is so, because there is no science to it. It's a touch and go process. You have mold your dietary responses around your bodily responses.
Why do I recommend this?
You are already eating less than 8 calories per pound of body weight. That is low. How is the progress coming along currently. Is the weight steadily falling? I think you indicated you are having problems right now.
By eating such a low amount, you are putting yourself between a rock and a hard place with no room to wiggle. You can't/shouldn't cut calories anymore, but your metabolic adaptations may have created an atmosphere where you are at a new, unusually low maintenance level where you neither gain nor lose by eating 1200 calories per day.
So you either starve yourself more, which I highly suggest avoiding, or you "reset" some of the metabolic adaptations that have occurred during your prolonged diet.
What you are eating is also important, so it might be a good idea to check this out too. Calories are ultimately most important. However, macronutrient selection/quantity is also important.
