This is only half true. Losing weight does relate to your lowered calories, but if you're not getting the proper nutrients from your food, you're putting your body at a disadvantage. I could eat very little and lose weight, but I could do it faster if I got all of my nutrients but still got less calories. My body would feel better, I'd have more energy, etc. There's an app that tracks all this stuff called Sustainabody, it shows you what vitamins and minerals you're low in and even gives you food suggestions while counting calories so you can lose weight.
