I do low carb (i.e. no grains, no refined anything, not much fruit) and only recommend it if it is a permanent lifestyle change, b/c if you use it as a diet you gain weight very fast once you eat regular carbs again.
Low carb requires, imo and ime, a lot of reading and a new way of cooking which you may not have time for. However, it is very fast and very effective.
Are you getting enough sleep? I found I could not lose weight no matter how much I exercised or how pristine my diet was so long as I was seriously sleep deprived.
Right now I swear by this 20 minute Shape dvd.
It is fast and OMG the results have been amazing for me. I've dropped 2 sizes, but only lost 3 lbs. And for some reason, it's never easy for me, I always feel the burn, which is kind of odd given that I'm doing harder, longer workouts other days of the week and those are easier!
I also try not to eat anything after dinner unless I'm truly hungry. If I'm not trying to lose weight, I would eat, but for weight loss I have found I need that long period from night to the next day with no food for weight loss.
Lastly, I think everyone's body is completely different, so experiment, read, see what you like and respond to.
For low carb cooking I recommend Kalyn's Kitchen
to get you started with recipes, Also, you'll need to keep an eye on milk supply and low carb. Most women are fine, but some have supply issues in which case, add in more fruit and see if that helps.
A sample menu for me would be...
Breakfast: Egg 'muffin' recipe from Marks Daily Apple site (kind of messy to make, but good for reheating all week long) or almond flax muffins with dark chocolate and sweetened with Splenda. Cottage cheese (full fat) or leftovers.
Lunch:Batch cook some taco meat and have taco salad with salsa, fresh guacamole topped with almonds. Once the meat is cook, the salad takes 2minutes to put together for a delicious & nutritious quick lunch. Then branch out into other salads--I did an asian meatball and slaw salad, buffalo chicken salad, italian marinated chicken salad, steak and bleu cheese salad etc...
Always batch cooking the meat so I had 3-5 days worth of lunch ready to go.
Dinner: Meat and non starchy veggie. Steak and asparagus. Ribs and green beans. Chicken and broccoli. Etc...
For low carb cooking, get into marinades and spices for flavor and variety. (I usually will use some sugar in sauces as its so incremental it doesn't hurt my weight loss and adds a lot of flavor).
