I ate green vegetables, salads and an occasional veggie burger. I supplemented with vegetarian protein powder and had fat free smoothies for breakfast. What the original tip was referring to was alleviating the boredom you experience with the food, which could lead you away from your original plan. But I've found ways to make it so enjoyable. It's still low fat and high on the flavor meter.
Greek salad is great because the feta cheese and onions are flavor packed.
And if it still isn't enough, use as little dressing as possible. Skip traditional dinner salads loaded with cheddar and other tasteless cheese. And if you can't imagine salad without the Ranch dressing, make a choice. I did this right after the holiday season. I drank a 12 oz.
