>"The only thing you really need to know is that you should be eating fewer calories than your body burns everyday. If you do this, you will lose weight – it’s science. Nothing else matters for weight loss. The magnitude of the caloric difference will regulate how quickly or slowly you lose the weight. [...] I naturally started eating healthy foods because I could eat more of them. If you eat a chocolate bar, you will still be hungry. For the same amount of calories, you could eat a few bowls of vegetables and be full. [...] Somewhere along the journey I picked up intermittent fasting. I like it but it’s also not necessary. I found that it helped reduce my appetite which means I can eat fewer calories."

I don't really think this is consistent. Basically yes if you eat less calories than are used you must lose weight, but the ease of doing this depends on what you are eating.
