Change is good but hard

Going through s divorce may be a huge upheaval, but losing weight does not have to be. In fact, the less "huge" you make it, the better. Choose to lose at a slower rate so that you have more calories to work with. Don't impose arbitrary food rules upon yourself, and tune out the noise of the braying dieting industry. Eat the foods that you enjoy. If possible, add a bit of physical movement - start gently, perhaps an evening walk after dinner.

My point is that you've been through a major shift in your life and you don't want to pile onto that with a bunch of new rules for shedding weight. Eat at a reasonable calorie deficit. It's great that you want to devote the time to taking care of yourself - but it can't be rushed. There is time. Breathe. Expect the best.
