That’s correct. It’s muscle loss, not age. If you maintain your muscle, your metabolism will not change. |
Ok now I get your logic and see your flaws. You can’t just subtract exercise calories from those consumed to say I’m eating 1500 burning 700 so living off 800. It doesn’t work like that. Let’s assume you BMR is 1500 and TDE with exercise is 2000. That is a deficit of 500. If you don’t track accurately, overeat on weekends, grab a snack here or there without thinking you can easily reduce the size of that deficit or cancel it out. I think op should meticulously track calories (weigh and measure food) eaten and her consistency with hitting her calories for a month before saying it’s not working. So often when it’s not working people just haven’t given it time or been as accurate or consistent as they think. Weigh also fluctuates and can mask any changes. Weigh daily and track the trend over the course of a month to really see if it is changing. I’ll also still argue that calories burned through exercise are not as high as we think and you should rarely eat more because you exercised. |
NP. Thanks for sharing. She seems great. |
I would agree muscle mass retention is critical as we age. I would also ignore any “calories burned” if we are talking about six miles of reported distance of movement through the day and whatever you might think you burned doing some weight lifting. Not only is it not accurate, you have to be working a whole lot harder than that to affect your real hunger for food indicating you actually need more fuel.
I’d learn how to safely life heavier weights and focus on large muscle groups. But everybody is not the same. These are suggestions. |
https://digitalcommons.uri.edu/cgi/viewcontent.cgi?article=1530&context=srhonorsprog The endocrine system plays a significant role in metabolic adaptation. There are several hormones that are involved in metabolic rate and regulation. These hormones play a role in the regulation of body composition, energy intake, and energy expenditure. Thyroid hormones, specifically T3, are directly related to metabolic rate. Hypothyroidism, or low-circulating thyroid hormone, contributes to a low metabolic rate and hyperthyroidism contributes to a high metabolic rate, which is more commonly referred to as a fast metabolism. A diagnosis of a hypothyroidism or hyperthyroidism is not the only condition in which these hormone levels vary. During a caloric deficit that is needed for weight loss, there will be fluctuations in these hormone levels (Trexler, E.T., A.E. Smith-Ryan, and L.E. Norton, 2014). .. This means that the brain receives signals that the body is in a state of low energy and the metabolic adaptations that occur are aimed at preserving body fat and reversing the effects of weight loss. In summary, there is a down-regulation of several hormones involved in regulating metabolic rate during a caloric deficit. Research shows there is a decrease in leptin, insulin, testosterone, and thyroid hormones with subsequent increases in cortisol and ghrelin. Evidence supports that these hormone levels remain in this fashion during maintenance of a low body fat percentage even after the period of active weight loss has ended. The body’s response to the changes in hormone levels that occur during and after weight loss is reflected in the arcuate nucleus (ARC) portion of the hypothalamus. Much like the hormonal changes discussed previously, METABOLIC ADAPTATION DURING WEIGHT LOSS 7 the changes that take place in the hypothalamus function to reduce the effects of weight loss by promoting metabolic adaptation (Maclean, P.S., et al., 2011). Therefore, the previous suggestion of telling OP to continue to reduce calorie intake while calorie intake is already low is making OPs metabolism even worse. |
