Caffeine is a reliable and safe stimulant that can increase energy expenditure, improve gym performance, suppress appetite, and attenuate energy deficits.

“caffeine super reliable one of the best things you could do you know where the data lies for upper tolerability and safety I think the FDA even has like a threshold amount that they say you're good to take it's like 400 which is pretty significant um and yeah you can get some level of increased energy expenditure from that but largely the benefit from the stimulant category I would say comes from the increase energy you have even as you go deeper into a deficit as well so as you enter into nutrient deprivation territory it becomes a lot harder to even move subconsciously let alone actually fuel your everyday activity so I'm not to say you should become a caffeine addict to support your deficit that's not necessarily sustainable but it's if you were going to use something to help attenuate an energy deficit or you know one day where you need a bump like caffeine is certainly a reliable way to DOA that increases metabolic output but also reliably increases performance in the gym and has appetite suppressing qualities and has safety data simultaneously so I would you know pretty blindly recommend caffeine for most people short of like special circumstances”
