Resting metabolic rates are influenced by how much lean tissue mass your body is comprised of.
To say that you cannot change it is absolutely ridiculous. Even fat consumes calories. By putting on muscle, you are increasing your body's caloric requirements thus increasing your metabolic rate.
Stupid video starts off by saying that exercise doesn't result in weight loss and then contradicts itself by saying that exercise can result in 10-30% of daily caloric needs.
10-30%!!!
It then shoots itself in the foot and says that a 200 pound man loses 5 pounds by only increasing their activity.
This is such rubbish.
There are also several different metabolic pathways, each efficient at withdrawing calories from different food groups; proteins and fat, carbohydrates and alcohol.
The basic principle of weight loss is consume less than you need.
You can do that by increasing your activity or decreasing your intake. Each one has different effects on the composition of the body but they both result in a net loss.
Now one's goal shouldn't be to loose weight, it should always be to increase the ratio of lean tissue vs fat.
To accomplish that you need to tweek your diet with the right nutrition and perform a mixture of anarobic exercises to stimulate protein synthesis via muscle fibre breakdown, and aerobic exercises to better oxygenate blood, increase circulation, improve nutritional delivery to cells and among many other things.
Do 3 days of resistance training and 1 day of intense cardio and 2 days of relaxed brisk walking and you will look like a million bucks in 6 months. Simple.
Eat lots of fibre with your carbs, 1 hour before resistance training, eat high protein afterwards, eat fruits high in fructose 2 hours before bed such as bananas and enjoy life.
Its not hard.
I saw this on my feed today, it's the second time I've seen it and it's such horsesh*t. The notion that you cannot compromise more than 30% of your daily burn through activity is stupid to the power of 10.
Couple that with the notion that at a rate of 1/lb a week (a good target) weight loss, that's 500 calories a day or 25% of a 2000 calorie diet and holy crap that 30% could make or break your goal.
