Yeah it sounds like you really had an ED there. Some people take theories or experiences of others way too seriously. I always felt fine eating RT4 and I still do it for the most part, but adding more variety, beans, and not being afraid of fat has helped me more than it's hurt me. I think eating whole food vegan is more important than eating loads of refined carbohydrates. Refined foods are only beneficial for strenuous exercise. On a regular day you're better off eating a variety of whole foods. I've found that I do better when I don't force myself to eat loads early in the day, have beans daily, stop when I'm full, and don't stress about what exactly I'm eating. That means eating out occasionally or having one or more avocados in one sitting or hummus is not a big deal. It's more about what you a majority of the time and getting proper overall nutrition from a variety of foods. As long as it's vegan it's fine.
What a bunch of !@#$%^&*. Sounds like you had an eating disorder of some kind, but that didn't happen because potatoes, or watermelon, or bananas lack protein. They are full of protein! Type in a full 2,000 calories of bananas or potatoes or watermelon for one day on any calorie-counting website and see how much protein you got that day, and fat too!
Maybe you have a fast metabolism and can get away with eating more fat, or maybe you weren't eating enough high-carb foods to sustain your weight. But plenty of us struggle to lose weight, even on a HCLF vegan diet. Our metabolisms are slow as sap. Eating more fat is a disaster for us. We MUST keep the fat very low to deal with our massive appetites and slow metabolisms. Otherwise, we WILL gain weight!
I personally enjoy eating beans occasionally, but it is not a requirement. I live on potatoes, bananas, and watermelon with some veggies thrown in. I get plenty of fat and protein without supplementing or adding anything extra like nasty oils.
Nutritionists are full of crap. You shouldn't need to take supplements for anything other than B12. Get your nutrients from your food! Not from the drug companies!
"Our bodies need fat from nuts, seeds, avocados, etc."
Wrong. You can get fat sources from these, but is it not required.
"except my lovely little box of protein powder. Because complete protein..."
You can get complete proteins from your food. Absolutely no reason to be eating someone else's magical-potion-science-experiment. People buy this crap because it's "trendy", not because they need it.
"Again, if I was getting enough fat from eating HCLF, then I wouldn't have had dry skin or brittle hair."
I've never had this problem in the 2 years I've been HCLF vegan. Thousands of other HCLF vegans have never had this problem. I have no way of knowing how much fat or calories you were eating to know what caused your issues. If you were under 5% fat or not getting enough calories, I would expect you to have problems.
"My metabolism isn't super fast."
How do you know? In comparison to my metabolism, yours could be a lot faster. I've observed some people, mainly males, can eat a lot more food (raw sugar, fruit juices, white rice) and still stay skinny. Whereas I have to eat all of my food in whole form. No smoothies, no fruit juices, and only brown rice, etc.
As far as your weight gain, I would definitely blame the fruit smoothies and pasta because that is more processed (aka not a whole food) and I can't eat unlimited amounts of that stuff either. But whole foods like potatoes should be very filling. They're safe.
Since someone clearly didn't plug in the foods I mentioned before, here are some results:
(the measure is set to 80/10/10 above in the pictures and measures how close you got to the goal.)
This is 2000calories per day if you wanted to mono-meal it. You get very, very close to 10% fat for the day just with mono-meals alone. You get plenty for 5%, which is the required minimum to remain healthy.
I've been HCLF vegan for 2 years and I have never turned to avocado or nuts to get any fat. My hair and nails are as shiny as ever. The second I eat any "overt fats", my skin gets oily and I break out in zits, I immediately get painful cramps, and my weight also shoots up quickly.
My potatoes, veggies, watermelons, bananas, fruits, pasta, beans, pizza crust, popcorn, etc all have tiny amounts of fat in them that add up over the course of the day. There's no reason to add any more fat on top of that.
