Worth noting that sadly, you cannot target where you lose weight from. It is different for everyone as to where they lose fat from first.
Also worth remembering that IF is a scheduling tool that helps you manage your food intake, but you still need to watch what you eat and make sure you’re not consuming too much. There are other benefits of IF as well, but as far as weight loss goes it’s a tool to make it easier, not a tool that guaruntees weight loss (if you still consume 3000 calories a day in your 8 hour eating window, you’re not gonna be losing any :P)
