High Fiber Foods

DOn't worry, you are not being gross! It is a problem, isn't it? I suggest psyllium husk (at health food store), you can put it in a smoothie with fruits, maybe yogurt, etc.

prunes
dried apricots
raisins

I remember once I ate a pound of raisins on a cross-country car trip. Let's just say I had NO trouble with constipation the next day.

I've been having a bowl of Fiber One cereal every morning. It's 80 calories and 40% of your fiber. It's been... helpful. I now go every day instead of every other day or every third day.

Try chia seeds

I eat a lot of broccoli, apples, carrots, pears, etc. I also eat some Fiber One products like cereal and chewy bars. They are not exactly low calorie, but eating one chewy bar a day will add about 140 calories, but also 35% of your fiber. You can also try fiber powders, like generic benefiber. All benefiber powder has been recalled, but the generic kind works just as well. Mix it in juice or yogurt, and it has very little calories. Also make sure you get enough water, especially with a high fiber diet. I recommend probiotics as well. You can get the capsules or the yogurt. I have a history of constipation, but once I upped my fiber and water dramatically, it has gotten 200% better.

(edit edit) Also note that leafy greens are way better for you cooked as in the raw form the good stuff is locked away and not readily 'bioavailable'.

...and need to be consumed with fats ideally as most of the nutritional content is fat soluable. The best bet is to research how certain food items react to cooking methods in relation to their nutritional profile. For example, cooked brocolli is best eaten with mustard; due to the fact an enzyme which is destroyed by cooking that allows many of the nutrients to be absorbed is readily present in mustard.

Not just for leafy greens either; if you like eating sweet potatoes for that omg vitamin a etc, make sure you cook it with some sort of oil.

Can't see your food diary so not sure exactly how you are eating. Agree with other poster: make sure you are getting 25 to 30 gm fiber per day (you can track it on MFP as one of your dietary numbers). MFP tends to give a low automatic fiber count, it gave me only 14 gm for a 1200 cal diet. Change it manually!

In addition to eating your 5 fruits and veggies per day (minimum), add complex carbs like bran-based cereals for breakfast, usually good for 7 gm fiber. Recently I found a great item that I use instead of bread, Orowheat whole wheat English muffins Double-Fiber; one muffin (both halves) have 8 gm fiber plus 5 gm protein for only 120 cal. Usually high-protein foods don't have much fiber.

Another product that I like much more than psyllium are the new fiber gummies (like vitamin gummies). I use the Walgreens brand called "Fiber Select Gummies", mixed berry flavor. They have two gm of fiber per gummy, usual dose is two per day but you can take up to four. Bottle actually says "Weight Management" (they make you feel full).
