Expecting to eat less can backfire during a weight-loss journey due to the potential onset of metabolic adaptation and increased cravings. When one restricts their caloric intake dramatically, it can lead to feelings of deprivation or binge eating. This unhealthy cycle can ultimately result in a lack of motivation, making it harder to stick to a plan. Instead, a balanced approach that includes nutritious meals and regular snacks may help sustain energy and satisfaction, fostering long-term adherence to healthier eating patterns.
