Let's say I'm basically just skin and bones, with almost no muscle at this point.
And, let's say I need 2,000 calories a day, to "power" the 'skin and bones' I have.
If I understand correctly, I can gain the benefits of caloric restriction for longevity by restricting my daily intake by 50%, to 1,000 calories.
But, let's say I start working out.
Then, I would acquire muscle.
And, my caloric daily requirement might grow to 2,500, or, maybe even 3,000 calories a day.
This would be bad, right? Since to gain the same benefits of caloric restriction for longevity as before, by consuming 1,000 calories a day, I would have to restrict myself to one-third of what I need, instead of just one-half of what I need? I assume that would be significantly harder.
Or, would caloric restriction at 1,500 calories per day with a 3,000 calorie daily need provide the same longevity benefits as restricting caloric intake to 1,000 calories per day for the same person with a 2,000 calorie a day need?
Thank you in advance! This is my first post on this forum. Hopefully, it'll be the first of many.
