I currently eat tons of vegetables (mostly broccoli, cauliflower, onions, cabbage, and non starchy vegetables), some proteins, fats (avocado, mayo, coconut oil) and some fruits (usually after a meal).

Where's the beef? I don't see any mention of meat at all in your post.

Eat mostly meat (beef, pork, fish),and some green leafy stuff. This is the basis and you can add to that at your own risk (and tolerance).

I find I can scarf down tons of vegetables until I feel bloated and still be hungry within an hour.

Yep.. Try scarfing down a 20 oz steak with a side of 2 scrambled eggs and tell me how hungry you are in an hour.

First off are you a male? Maybe think about focusing on gaining healthy weight if so.

I've dealt with the whole acne thing and imo you haven't cured your acne you've just managed to control it by limiting otherwise healthy foods. In my experience getting enough Preformed Vitamin A, Vitamin D and vitamin K2 mk-4 along with sufficient zinc has been the biggest help in my chronic acne. Before I started all the supplements I was always eliminating foods that would cause me acne, most of the foods no longer cause it. I can even drink milk which for me used to be guaranteed acne.

My advice would be to input your food in something like cronometer or fitday.com to make sure your getting adequate nutrition. Along with this make sure your getting adequate sun or supplementing Vit D, 15k IU retinol(vit A) through food and supplementation and around 1mg of k2 mk4 daily from supplement.

If you want to do cardio switch up the intensities i.e. run for a couple blocks, sprint for a block, walk for a couple blocks etc.

I am also underweight and I also feel like I am starving on low carb. I need starch to feel satiated. I had moderate to severe non-cystic acne from ages 15 to 25 and my skin is now FINALLY clear thanks to my paleo experiment(s).

If I were you, I would try adding more simple starches and animal fats to your diet while also focusing on maximizing/supplementing the nutrients which are so often helpful to acne: zinc, vitamin D, retinol, idodine, and IMO saturated fat. And avoiding commonly inflammatory things like grains (although small amounts of white rice are a-ok for me), solid dairy products, and o6s.

To me your diet seems too high in vegetation (nutrients from which are barely utilized without fat in your stomach. Do you put butter on them?) and WAAAAYYYY too low in fat and calories. And all your fats are o6s. Of course you're hungry all the time and feel like crap. You're one step away from a vegan, looking at your OP. And skinnier than most of them!

You need to gain weight, BTW. I wouldn't call it 'binging' to eat food and gain weight. My BF is 5'8" and 157 lbs, and he has skinny arms and legs and wears a size medium; you must be so tiny! And if you feel you are 'flabby' you need to gain muscle mass. Do you do weight or strength training?

I'd say your problem is all the veggies! Beans and potatoes are the most starch rich veggies, and they will trigger your insulin and make you hungry again soon. Keep the more nutrient rich veggies, cut down on sugar and eat more meat and fats. Proteins satisfy, so eat them first and then the veggies. And ditch the fruit, it'll make you hungrier much faster to eat it than to not eat it. Adding carbs to food makes you hungrier faster, and bloated with poor digestion. And don't be afraid of the proteins, eat them full fat and don't just keep to fish and chicken, eat the red meats.

I have similar issues with overeating (but I'm not getting fat) and here are my ideas:

My first point was to restore some sort of satiety signalling in my body which appeared to be broken (perhaps similar to leptin problems). Making a conscious effort to get a decent portion of protein in the morning and not going to heavy on the veges (yes I had to cut down on the huge amount of filler veges) seems to be helping alot. Perhaps one mechanism is the reduced digestion load on the body. Fruit has its issues with cravings.

Using a protein such as lamb liver for lunch makes it very hard to binge as well as I find satiety approaches quickly due to the intensity. These are just some ideas - of course make sure you are getting 'enough' calories. Not to mention the nutrients which may settle some sort of deficiency inspired craving.

The low energy thing is really the question mark here though, as eating less seems counter-intuitive.

• Beans aren't vegetables. But anyway there is nothing wrong with eating starchy tubers- potatoes and sweet potatoes are basically fine. Since you said potatoes trigger your acne, have you tried sweet potatoes?
• Maybe this is nitpicking but if you're eating store-bought mayo it's full of nasty soybean or canola oil. So I would suggest cutting that out. Also what's wrong with animal fats? Why are your only fat sources mayo, avocado, and coconut oil? You don't seem to be eating much meat or fish.
• Are you eating low-carb? If so you might try lowering the fat and protein and upping carbs (sweet potatoes, white rice, etc. I also feel bad on high fat. The answer to everything is not "eat more bacon" although I'm sure you'll get plenty of that advice. Some people lose muscle and gain fat when carbs are too low.
• Regaining muscle will be a lot easier if you lift weights. I'm sure other posters who know more about resistance training than me can expand on what you could do.

I agree with everyone else that you're basically underweight and need to eat more protein and probably take supplements.

But on a practical note: bingeing on veggies totally doesn't fill anyone up, but it does stretch the crap out of your stomach. Protein is very satisfying, but you never get that "full" feeling in the belly. Starch lies somewhere in between, it's bulky and provides decent satiety (when eaten with protein and fat). If you can find starch that doesn't flare up your acne, do it. Even some franken foods, like "gluten free" breads etc. might be a good idea for you, depending on how your acne reacts to it.

So, in your search to be full from veggies alone, you've probably stretched your stomach out a TON, and now nothing really makes you full.

So, for a few days, just suck it up and eat protein/starch and very few veggies, don't eat until your stomach is bloated, just eat some objectively pre-determined amount, and give your stomach a chance to shrink back up to a normal size. Then hopefully once your diet is less vegetable heavy and your stomach has settled a little, you'll be able to feel that belly-full feeling AND be satisfied with meat/protein/starch.

But, like I said, you're way tiny and should make sure that you're replacing those veggies with lots of calories (which shouldn't be hard, considering the caloric density of vegetables vs. meat/fat).
