I have a hard time staying under the calorie goal I set for myself. I've found that as long as I drink at least a gallon of water, and my ratios are good, my calories aren't greatly important. I'm talking a little over, not major over. I will always eat when I'm hungry, but if my calories are off, I eat a huge salad before I eat anything else..... dark chocolate almonds are my weakness.... I find I need something that my body considers sweet every day. Thankfully unsweet coconut tastes sweet, and mayo tastes sweet. Don't beat yourself up over it, just be more observant the next day. As long as your carbs aren't too high, and as long as your ratios are close and your calories aren't several hundreds over, you should still move the right direction I think.

I've actually had a harder time reaching my calories. Most days, my meals leave me at around 800 and I have to scramble for something for a after dinner snack. The few times I've gone over, I've kind of counted it as a loss, because it's only one day, but as long as I'm not 500 calories over, I'm still at a deficit.

This has been an issue for me as well. I had days when my calorie intake was getting beyond my threshold and I would worry. Sometimes it is because I'm craving for something and others just because I'm a little bit hungry. Obviously, I tend to try the drinking water/tea/coffee first and add some heavy cream (not too much, though) and see if it makes me feel full. If despite the liquids I still feel hungry, I don't suffer for it... and munch something. I try not to eat something too caloric buuuuuut, if I can't handle I will just allow myself to do so (always from keto-friendly food, never cheating).

If I'm energetic enough, I'll try to practice some sport at home (walking at home videos are awesome!!) or go for a walk... that way I'll be burning some calories and feel less guilty about it.

Also, I bear in mind that there are 3 different caloric threshold:

1) One in which I know I will lose weight (sooner or later, since I'm a slow loser). (In my case 1300 cal/day)
2) Another in which I won't neither lose or gain. (Less than 2000 cal/day is fine).
3) You will, eventually, gain weight. (More than 2000 cal/day)

I always try to stick to the 1st one, but some days I go beyond 1300 cal, and I have reached the 3rd one only a couple of times.... and just tried to keep it fine the next day. IMO it's always important to remember that adding fat will make you less hungry and also proteins (in case you haven't reached the ratio of the day), but not too many since we know the body can transform them into carbs.

Hope my ideas help! Don't be too hard on yourself. We're already doing a lot taking care of ourselves with our daily meals, which it is something that requires tons of our energies!

I try to combat this two ways: planning and portioning

I try to plan as much as possible for what I eat and then I measure out the portion I will be eating. It's tedious and I get annoyed but my results are far better when I do this. If I go over severely on calories but my macros are good, I chalk it up to stress and/or hormones and stay more diligent the next day.

Usually days I go over on my calories (because I was hungry, and I like to listen to my body) I still record a loss, and usually it is the day after I ate more calories then i do the rest of the week. It can be addicting, but I weigh every morning after I use the bathroom.

If I eat something that is not a leafy green, or fat/protein source then I will probably not record as big a loss(if any) that week. If I have to "cheat" or eat more, I make sure it is uncured bacon, a hardboiled egg or some cheese WITH LOTS of water. My goals are to lose fat, but also maintain the muscle I do have. If I maintained all of my current muscle mass to get to 18-20%BF that would put me at about 140. Today I measured 179

For accidentally eating more than you planned, it is nice to have those little 1 C/8oz tupper wares (rubbermaid or gladware) to portion out yogurt, or some cheese, etc... It was a good investment, at the IKEA I go to, they have little 2-3oz containers (inside Of a multipak which is clear with green lids) which are great for nuts and a little chunk of dark chocolate.
