Will power is very over rated.
It always breaks down long term, and reminds me of those awful positive affirmations people used to parrot back in the 80s and 90s.
The reality is that the more effort you have to put into maintaining a regime, the harder it will collapse, and the sooner you will lapse into old habits.
My aim is always to move forwards into something that I prefer, rather than move away from something I am missing.
Sooo, in your situation, my lazy, habitual mind is actually seeing opportunities for increasing deliciousness and food intake, rather than trying to battle on with grit and determination.
First question: Are you hoping to maintain, lose or gain weight? (cos that makes a difference to what you can choose to do)
Second question: Do you want to go to bed on a full tum, or a not full but not hungry tum?
Third question: Do you want to snack between meals, or stick to mealtimes?
I loathe snacking. Just makes me hungrier. So my responses to those questions would be 1) maintain or lose weight, 2) not full tum, 3) stick to mealtimes
So I would just have a bigger evening meal when I stopped the cab in the evening to eat, including an enjoyable 'treat' or cheese, or nuts, or a low carb cake, or low carb hot chocolate. Then I would forget all about food until the next morning.
Depending on your responses to the questions, you can tailor make a way of eating that suits you and your lifestyle.
