A babybel isn’t the worst choice so I think you should be kind to yourself and maybe see it as a step in the right direction.
What’s your fasting window? Don’t try and go too extreme too soon.
Is the snacking unconscious (eg passing fridge, reach in and eat before you think) or hunger, or compulsion?
It’s very hard to change our habits and we evolved to gorge on abundance. You can’t expect to overcome millennia of evolution with mythical willpower! But there are things that can help.
chewing sugar free gum can give your mouth something to do - it’s not ideal if you have gut issues because of the sweeteners but it can be a stop gap.
thinking differently about hunger and what it means - in ancient times, it was the body’s way of getting you up to go hunting. You might track your prey for a day and half before eating again and be no worse off for it. But we feel like we have to eat or we might faint which is actually quite unlikely.
Also we have a second phase of digestion which is very important but we interpret tummy rumbles as “better eat” and disrupt the cycle. I find that stopping and thinking about it can help a lot. If I don’t it’s like I’m operating on auto pilot in survival mode, but if I make a decision I find the urgency fades.
Drinking helps too - water not booze 😉 thirst and hunger signals can get mixed up.
And sometimes I need something else but I’ve learned over the years to eat instead of tuning in to my body properly.
It’s ok to take it slowly, or shorten the fasting window. It’s also important to be in harmony with your cycle - fasting before a period isn’t advised. Try not to be unkind to yourself - change takes time.
