If you eat a high carb diet, yes, because you will constantly be hungry as a consequence of insulin resistance and unstable blood sugar. If you eat a low carb, high protein diet, you'll never be hungry. There are no cravings. This makes it easy to lose fat without even exercising.
This is the effect of cortisol which I have been harping on for several posts. Many people are so sensitive to the effects of cortisol that when they reduce their exercise load, they begin to lose weight and gain muscle by commensurately reducing their average cortisol secretion.
Lots of exercise + a "normal" diet can lead to weight loss, but focusing on a low carb, high protein diet leads to weight loss in the absence of exercise. Again, calories in = calories out isn't quite the way it works. If you take advantage of hormones, you can lose fat without any exercise while eating a slight caloric excess of your metabolic requirements. I really, really prefer the latter. Less work, more meat. It also preserves muscle when cutting fat. The biggest benefit of all, though, is the satiating effect of protein. You'll never be hungry again, and that's critical to sticking to the plan and staving off cravings. It also leads to stable blood sugar, constant energy levels before and after meals and throughout the day, and a better quality of life as a result. Good ol' gluconeogenesis.
Fasting leads to insulin and leptin sensitization which leads to disinhibition of hormone sensitive lipase in fat cells. That allows your fat cells to release stored fat which means you're using fat for energy. Win.
See above for another approach I've been doing it for almost 3 years now, and my weight has been completely stable (9-10% body fat) with no exercise and paying no attention to calories. And in the past 2 months, I've put on 20 lbs. in the gym doing strength training; very little of that was fat. Haven't taken a jog in maybe 2 years. I'm not even doing HIIT sprints. The importance of the macronutrient composition of your food cannot be overstated.
