My BMI is about 22. A couple of years ago when I was obese (35 BMI). I have gotten into a routine with eating. I fast between 1pm and 9pm or thereabouts, not too strict with it.
Salad or meat/fish and veg or salad for lunch, no carbs.
Full fat greek yog, chopped fruit /berries and nuts for an after work snack.
Dinner is meat or fish and veg, chilli, stew, curry 80% homemade. Again keep carbs to a minimum as id rather fill up on veg.
Make my own low sugar muffins and granola for snacks. Have a sweet tooth and like a scoop of ice cream regularly or a slice of cake, enjoy a couple of squares of dark choc and peanut m&m's. I don't feel deprived.
I do track on nutracheck every day and weigh myself once a week to keep an eye. Also strength train 5 x a week.
Also don't drink alcohol now, I used to drink daily, I think quitting changed my health and life.
It sounds hard work when I read it back, but I'm 100% happier and healthier than 2yrs ago when I ate and drank what I wanted and didn't exercise.
