Hello dear hunters and gatherers,

I bet you know the feeling when you had eaten too less a couple of days and then your metabolism slowed down. I'm currently feeling that way and I want to get out of this survival mode. But how do I do this without gaining weight? My understanding is that I should just eat more calories and carbs. I guess movements could help too but I walk a lot by feet anyway. Are these assumptions right? How many calories do you suggest? Are there any special substances which could help? And another related question is how much should I eat so I would still lose like 2kg but wouldn't get into survival mode again.

I think this information will be useful to give some recommendations:

My weight is 64 - 65 kg

My height is 175 cm

Thanks in advance
