If been over weight all of my life. just started eating low carbs, trying to keep my carbs under 60 grams a day with one cheat day a week. healthy?

Ok: Yes and increase your vegetables and fruits.

Healthy diet: Eat a healthy well-balanced diet, 3 meals without snacks. Caloric restriction if you need to lose weight. There's no magic here. Find an eating plan you can follow the rest of your life, not a short-term diet. Check w/your registered dietitian. Don't try to overly restrict or supplement fat, carbohydrate or protein. Eat each in a sane and balanced amount.
