Welcome to Gaia! ::

I eat whatever calories I need. I try to keep the sources balanced.

As for filling, I would go for starches and complex carbohydrates.

You know, bread, beans and just grains in general. Avoid sweets and fat as sources of energy, but keep a source of lipids in your diet, they are essential, keep the ratio of mono to saturated fats balanced, and for the sake of your long term health, avoid trans fatty acids(Anything with the word hydrogenated in the ingredients list, even if the nutrition facts say "0g Trans fat." They manipulate the serving sizes to be misleading.

I bake bread atleast twice a week.

here's a good site for that:

Lifestyle is the real key to weight-loss/gain. A sedentary person must work to overcome their lifestyle especially. I put on a lot of extra weight due to depression, over the course of about 3 years, and lost it all and then some in one summer. About 40 pounds.

Active muscles are key if you want to be able to process more carbs. You'll need a lot of them to get what your body needs.

The body was designed to move.

For weight loss I'd suggest more exercise rather than a diet, assuming of course you're cutting out unneeded calories like soda, sugar, etc.

As for filling things that don't have a lot of calories, think raw vegetables like carrots, lettuce, cucumbers, raw spinach, and the like. There's a reason people on diets eat a lot of salads. Raw carrots especially are good at filling you up while not adding a ton of calories. Raw foods like that tend to have a lot of fiber and not a lot of calories; it's cooking them that makes them digestable so you get more calories from them. Also drink more water, because a lot of time when people feel like they're hungry, they're just dehydrated, and water fills you up anyways. Try drinking a full glass before you eat a meal, and one afterward. Also try to stop eating when you feel about 80% full. Americans usually stop when they feel really full, but it can take 10-20 minutes for your stomach to realize your full and tell your brain, so after you've finished off a plate try waiting about 15 minutes. If you're still hungry, eat a bit of fruit for dessert.

Also, something that's really helped me, don't completely cut anything out of your diet. Restricting foods just makes you want more. A lot of times people think "Oh, now that I've lost 10 pounds I can afford an extra slice of cheesecake" and end up gorging themselves... Eat some of the unhealthy things you want, just eat less of them and exercise a bit more later, that way you won't feel deprived.

You can cut our processed foods by making fresh ones.

You should never binge. by trying to preserve a behavior you know is bad you are inviting it into all the other days. You should just look for more thoughtful alternatives. Tasting good is not a quality solely owned by junk food.

The alternating between upper and lower body parts for each day (since it'd be easier for me to do my exercises on consecutive days) sounds like it would work fine with me. I am wondering if it'd be bad to add one more day of exercise to the plan? Since I am only doing lighter, beginner poses to build strength an flexibility so I'd be able to progress over time.

I agree with the no-binging and the eating of processed in small portions everyday. I always seem to binge on one day of the week, though, but with discipline I will try very hard to avoid this!

My sister is testing out the Kelloggs All-Bran Bran Buds to help her bowels move more (high in fiber). She suggested for the small portions of processed foods each day that I have a handful of this bran cereal after each meal (3 meals a day, usually consisting of vegetables and protein in any form...2 snacks a day in between meals, usually a mango or a pear). Would it be okay to have a handful (of bran cereal) after each meal or just with one or two of the meals?

Other than this...the hummus and chips idea sounds very tastey!

As far as flavorful foods go, your best friend is a full spice rack. Some combinations I can think up right off the bat are...

Dill/basil/garlic - Greek/Balkan
Basil/oregano/garlic - Italian
Cumin/garlic/chili - Mexican
Cumin/ginger/chili/garlic - Indian
Ginger/chili/cinnamon - Chinese

A good, filling breakfast is a bowl of oatmeal (with various other seeds and grains). Here's my recipe:

Mix together three parts quick oats, one part wheat germ, and one part milled flax seed. Use this as your oatmeal base.
Bring about 1 1/4 cup water to a light boil and add 1/2 cup of your oatmeal base. Cook it for about 5 minutes or so; if you cook it too long, the oats absorb too much water and it gets gummy.
Mix in 5 tablespoons of hulled hemp seeds and one tablespoon of chia seeds.
Add cinnamon and honey to taste.

This makes a nice big bowl of deliciousness that is incredibly filling (like, you probably won't be hungry at lunchtime). If you do get hungry at lunchtime, something light like a nice green salad would do you well (without dressing, if you can manage).

For dinner, any combination of rice and legumes (beans, lentils, peas, etc) is great. Here's an easy and tasty recipe for something like that:

In a medium saucepan, heat up some oil (I tend to use either coconut oil or olive oil, more often the former) and saute one onion, two cloves of garlic, 3-5 carrots (depending on size), and one red bell pepper, all diced finely. Add in a few other veggies like celery or parsnips or something if you like.
Pour in three cups of water and one cup of lentils (I tend to use red lentils for this recipe, but green lentils or split yellow peas work equally well). Add in a vegetable bouillon cube and whatever spices you like (I use lots of curry powder, a bit of thyme and sage, a shot of chili powder, and whatever else I have on hand that seems like it will go well with everything else) and bring it to a boil.
Let this simmer, uncovered, until almost all of the liquid has been absorbed (or boiled away).
Spoon this over a bed of brown rice (tip: for an extra flavour boost, put another bouillon cube in the rice water).

Now, obviously it will get kinda boring if you just eat the same things every day, but hopefully you can find other recipes to work into your daily eats. As mentioned, exercise is key to all this. I don't think it really matters what you do, just get moving for at least half an hour to an hour every day.

Good luck!
