No, because you're not really reducing calories (aka starving) on keto. The fat you're eating on this diet will signal your body that there's plenty of energy coming its way while also tricking it into ketosis.
When you're on a low-fat and low-calorie diet, however, your body enters adaptive thermogenesis, commonly known as starvation mode . It's your body's way of trying to preserve energy and involves breaking down muscle and reducing the resting metabolic rate (RMR). Keto is different. It provides enough protein to prevent muscle breakdown as well as sufficient fat so your body can make ketones as fuel.
