Weight loss occurs when the body expends more calories than it intakes. Unfortunately, our bodies are not optimized to lose weight, which is why
most popular diets ultimately fail. Our body fat (and our weight) is designed to regulate itself. When caloric intake is drastically reduced (i.e. dieting), your body senses starvation and will produce hormonal signals that cause your metabolism to slow down while at the same time increasing your appetite – your body’s attempt to protect your fat stores and preserve your life. A similar occurrence happens when we gain a little weight, our body speeds up metabolism and suppresses appetite in an effort to lose the weight and keep us from getting too heavy.
