These are all great ideas! Everyone's nutritionist is different - mine says 3 meals, 3/4 - 1 c. food each, and maybe one snack. I stick to 1000-1200 calories/day and often do supplement with a sugar-free smoothie from a nearby sports-performance smoothie shop.
That said, one thing she reminded me last time is that almost EVERYTHING has some protein - broccoli, bread - she said those 1-2 grams can add up to a significant serving by day's end. I don't always do it perfectly, and honestly follow Weigh****chers to manage my intake - that said, here are my key 'rules' - nothing too new or shocking, I'm afraid...
- Eat protein first! I have an egg and 1/2 ounce of crispy bacon at breakfast (with 1 slice of carb-curber bread - 50 calories with 7 grams of fiber!)
- Tuna salad, 1/3 c. at lunch with 1/2 ounce almonds and 5 water crackers
- Often a smoothie (33 g. protein) or a soy latte (12 g. protein) snack
- 3-4 ounces fish/chicken/beef (mostly fish, some chicken, rarely beef), 1/2 c. veggies, and sometimes a wee bit'o'carbs (I love veggie spring rolls)
I'm not perfect nor do I claim to be, but I'm holding up just fine with this. My nutritionist also suggested looking at the whole week - rather than daily - and often it just works out for me overall.
Hope that's somewhat helpful!
