Before I answer Twoo's post I want to repeat that, in general, there is no need to count calories on Bootcamp. There are personal reasons some individuals count calories, and it can be a useful tool in diagnosing why someone isn't losing weight or is on an extended stall. Please don't feel that you should be counting calories because of the recent discussions on the topic.
"However, I feel to make any further progress I need to [count calories]... My calories needed per day to maintain current weight of 10 stone 12 is 1450cals. To lose just one lb per week I need to cut 500 per day. This creates a deficit of 3500 cals over the week, which equates to 1lb of fat lost. So that leaves just 950 Cals a day."
Is one pound a week a reasonable rate of weight loss for you? For a person of average height who has a lot of weight to lose then 1-2 lb per week is an optimal rate of weight loss. I believe that at your height and weight, 950 calories per day is unnecessarily restrictive and will result in you losing lean body mass. This is something you can ill afford if you are limited with regards to exercise, since you can't easily exercise sufficiently to maintain or rebuild muscle mass. Another consequence of a too low calorie intake is that your body will put maintenance and healing of your body tissues and bone mass on hold until your calorie intake rises again. So you would be setting yourself up for an immediate weight gain when you start eating more again. I suggest aiming for half a pound weight loss per week, hence a daily calorie intake of 1200 calories.
"This is where I think this woe comes into its own. To have a nutrient dense 950 cals a day made up of the right veg, meat and healthy fats, this would sustain and satiate you."
A nutrient-dense diet is a great goal. Since a LCHF diet is more satiating at a lower calorie intake than a standard diet you should be able to reduce your calories below your TDEE without feeling extra hungry.
"I’m at a further disadvantage too as I’m disabled and I’m limited to what exercise I can do. So unable to create a deficit with exercise."
This makes remarkably little difference. Exercise is important for health but not essential for weight loss.
"Therefore starting today I am going to have to record everything I eat, watch my macros and keep within 950 cals per day."
I think it is a good idea for your to start logging your food so that you can calculate your calorie intake and make sure your macros are optimum. I have the following recommendations:
Aim for 1200 calories per day initially then reassess in a couple of weeks.
Don't think of 1200 calories per day, rather expect to eat 8400 calories (1200 x 7) per week. Some days you will feel hungrier than others. When people that are naturally slim eat more calories than they need in a day, they spontaneously reduce their calories the next day. That's a reasonable model to follow.
Introduce an eating window by fasting for at least 16 hours between dinner and breakfast. If you eat two nutrient-dense meals per day without snacks in between then your insulin levels will be perfectly primed for weight loss. This is another area where calorie counting can potentially let you down. It's better to have a big lunch and a big dinner with nothing in between, than to have a 'lite' lunch but need to snack a couple of times before dinner. Losing weight on LCHF isn't just about the calories or the carbs, it's about keeping insulin levels low. Fasting will help lower your insulin levels.
Twoo please do let me know what you think of my comments and if there's anything you want to discuss further.
