Whenever somebody asks me for diet advice, I always break it down to the very basics of eating clean. You can't eat healthy when your fridge is full of junk.
On health-rage weeks, I make sure there is absolutely zero processed food in my pantry. Eating clean doesn't mean counting calories. It means cutting out all things artificial, pre-prepared, frozen and containing additives like artificial flavorings and sugars. I'm not big on cooking rice at home, although I will occasionally allow myself a kick-ass filipino breakfast. The trick is, to prepare your own food from scratch - this is the only way you can know 100% what you are putting into your body.
I'm a big fan of making cabbage soup - super low on calories and if prepared well, mega tasty. I also make my own pumpkin soup - soups in general are a great way to feel full without feeling heavy. Roasted or baked potatoes are also amazing, with a side of broccoli, and even some bacon bits. You can eat "clean" without cutting out all the good stuff completely - reasonable portions are the only way to go.
I eat a lot of boiled eggs - on stricter days consuming only the egg whites - and obviously my fridge is also full of green apples - I'm a big fan of sour fruit. When I blend juices, carrots are my favorite, apples, cucumber and fresh coconut juice.
Clean eating doesn't have to be hard and tedious. But the first step is to clear out the junk. Out of sight, out of mind.
