Final answer:
To achieve and maintain healthy weight loss, balancing energy consumption with physical activity is necessary, and a balanced diet should be favored over reliance on supplements. Combining dietary changes with regular exercise is more effective than either alone. Fad diets may lead to nutrient deficiencies and are not sustainable for long-term weight management.
Step-by-step explanation:
For weight loss that exceeds what is considered healthy or when there is a need for nutritional supplementation, it is essential to monitor food portions and balance energy consumption with physical activity. Consuming more energy than is expended leads to weight gain, while burning more calories than consumed is necessary for weight loss. It is crucial to have a balanced diet and not solely rely on supplements, as they cannot replace the diverse nutrients and benefits of whole foods.
Behavioral interventions that combine diet and exercise have proven effective in maintaining a weight loss of at least 5 percent from baseline. Regular exercise can boost metabolic rate, but it is usually insufficient on its own for significant weight loss without dietary changes. A healthy weight loss plan involves reducing caloric intake from food while increasing physical activity.
Fad diets promising rapid weight loss often require supplementation due to their lack of certain nutrients, and they can lead to health problems if they prescribe overconsumption of specific nutrients. A well-designed weight management strategy avoids such extreme diets and focuses on sustainable, balanced eating habits alongside consistent physical activity.
