With keto or another diet? I find any cheat RUINS my focus to the point where I just...it m ight as well be a cheat month if I do that.
This is where having some cooking skills helps.
I'm not low carb, keto, or paleo, but my diet is basically a paleo style one with white rice, sourdough bread, beans, lentils, and dairy.
But I do use a lot of recipes from paleo sites and cookbooks since they're whole food recipes, unless you do the paleo baking stuff with nut flours, which I don't.
For example, I love french fries, but instead of getting a helping of deep fried Omega 6 fats, which are showed to cause inflammation in excess, I do oven fries, in coconut oil, which doesn't doesn't have the health issues that omega 6 oils have, and sprinkle sea salt.
It scratches that itch without the processed garbage veggie oils.
If I have a sweet tooth, dark chocolate or full fat greet yogurt with berries and real maple syrup.
Compare that to something like ice cream and the calorie difference is huge! The full fat yogurt and fiber in the berries satiate me, so I'm not coming for more, unlike ice cream.
