If you're already at optimal weight, why risk making a change that could disturb your advantageous homeostasis? If anything, I would think that taking supplements to boost metabolism would be best for you if you commit to doing it continuously. On one hand, calorie restriction extends healthspan, on the other, it slows metabolism and can make one more susceptible to injury (lower testosterone and other neurosteroids and structural hormones). Faster metabolisms also seem to lead to greater healthspans and more fun and motivation and may reduce the amount of pro aging metabolic byproducts. I feel like it's 6 of one and half dozen of the other, just that faster metabolic rate is more fun. Body Builders seem to have great healthspans.
Any time you cut calories, you risk losing BAT (Brown Adipose Tissue) which is responsible to increasing or maintaining higher levels of metabolism. There aren't many ways to improve this, though I seem to remember reading that Viagra could do it some what... but it was producing "beige" adipose tissue rather than brown, so I'm not sure what the repercussions of that will be... whether it's a net benefit or bad thing that will lead to harmful byproducts... Thyroid hormones and testosterone iirc, will increase brown fat if high enough levels are maintained for months, though these are both harder to get scripts for than Viagra apparently...
That said, I'm sure there are benefits to be had with calorie restriction, and if you can find easy and available ways to increase satiety, motivation, libido, and energy levels while on it, then I'd love to hear about that. I guess I'm more of a "More and Faster" kind of life extensionist as opposed to a "Longer and Slower" type. Tried it, got depressed and felt like I was fading away. I still like several day supplement and water fasts that involve protecting brown fat and I have to wonder if cofactoring adrenaline production and it's catabolism will lead to similar attrition of senescent cells through enhanced catabolism... though this of course comes with injury risks.
