I'm no expert, but I believe some of the statements would be true if caloric intake would be drastically cut. I believe no one should ever eat less than 1500 calories even if it means weighing a little bit more. Some people tend to cut down too much, and I can see where that would do something to you mentally. I'm sure this statement won't be popular, but you can be fat and healthy. Genetics determine your weight more than anything else. This is a proven fact. That being said, I think it would be dangerous if you were extremely obese 300+ lbs or so. Just a 500 calorie a day reduction can make a big difference in your weight over time. This isn't drastic and I think anyone could live with that.
Genetics determine nothing, ever. That probably sounds excessively absolute, but it is true. All genes are dependent on environment for expression - I don't care what your genes say, if you're stepping in lava, your weight is going to 0 pretty fast, just to use the most extreme example.
Somewhat more realistic, if you somehow had some incredible kind of mitochondria with DNA that allowed them to produce 200 ATP per molecule of glucose (probably not chemically possible, but still), it wouldn't matter much if you lived in tundra with less than 1% of your calorie intake being carbohydrate.
We don't tend to see any obese and or even overweight BMI's in people living in pre-agricultural lifestyles - it seems most calories in that environment are too hard and unappetizing to be worth pursuing. In the modern environment, there's probably are a variety of genes that influence appetite and preference that trend towards various levels of weight. Such people can still be actively managed by altering the environments one spends a lot of time in. It generally takes something pretty severe like defects of leptin production or something like Prater-Willy to be what could be fairly called a genetic reason for being obese.

What is your source for this?
Growing up, my entire family was slim. I was a very skinny kid and a slim adult.
So, if genetics played a big role, I would expect to have a difficult time gaining weight. Yet in my late 50's, I had no trouble whatsoever blossoming myself right into the obese category. It was ridiculously easy. Too many calories, not enough activity.
Tl;dr: Genetics aren't a factor. How many calories you shove in your pie hole daily absolutely is.

Very wise of you to say that genes are dependent on environment for expression. Most people will go through life never understanding what that statement means or its implications.
