Freelee is (or was) a raw vegan. As far as YouTube Vegan role models go, she is far from the best.
Raw vegans do eat a lot of fruit. but that's not all they eat. the main thing is that they don't eat much (or any) processed foods. and for them, processing includes cooking.
It sounds pretty crazy but there is actually some good science and nutrition info to back it up. But don't for a minute think it's a good weight loss diet.
In order to get adequate amounts of protein, raw vegans have to eat lots and lots of food. Freelee's daily meal plan regularly went over 3000 calories a day. The reason she was so skinny was that she was a fitness instructor and an avid bike rider. So she burnt off all those calories.
There are also come nutritional negatives to raw food diets. Some of the best things in food only get released with cooking. A less extreme version of the raw food diet is the Raw Till Four diet (RT4). You eat raw all day but have a cooked meal for dinner. Most of the Whole Food Plant-Based diets are a compromise. lots of raw food but also include a lot of cooked foods. For instance, a good strategy in WFPB diets is salad for lunch and cooked veggies for dinner. In fact, if your goal is weight loss, your best bet is the WFPB diet. Fuhrman's Eat To Live has a 6-week weight loss plan.
BTW, chocolate is a drug. You are probably addicted to it. (I am too). It contains caffeine, fat, sugar and the alkaloid Theobromine. Other examples of alkaloids are cocaine, caffeine and, nicotine. Some guys with an MRI did some research and found that combining fat, sugar, and caffeine together makes your brain light up like it's on cocaine. If you ever wondered why Starbucks has a line out the door for $5 lattes - this might explain it.
The good news is that if you eat a WFPB diet and avoid fat and sugar your intestinal flora will adapt over time. Surprisingly gut bacteria who eat a lot of fat and sugar produce a hormone-like substance that when it hits your brain makes you think you want some more fat and sugar. The more you avoid fat and sugar the less you will crave it.
