Briefly describe the three components of a healthy weight-loss and weight-maintenance program

Answer 1

A healthy weight-loss and weight-maintenance program consists of three components:
Setting reasonable goals: When it comes to weight loss, slow and steady is the way to go, and weekly weight loss should not exceed 1-2 pounds. Rather than making dramatic dietary changes, small changes such as reducing portion sizes and cutting back on energy-dense snack foods can make a big difference in overall energy intake.
Choosing nutritious foods in moderation: Weight-loss plans that drastically reduce caloric intake and offer limited food choices often leave people feeling hungry and dissatisfied. A key recommendation in the 2015 Dietary Guidelines for Americans is for people to develop eating patterns that emphasize a variety of nutrient-dense foods within all food groups, but at an appropriate level of calories.
Increasing energy expenditure through daily physical activity: In addition to choosing nutritious foods in moderation, you can also help tip the energy balance equation toward negative energy balance by engaging in physical activity. Walking 1 mile each day, which takes people about 15-20 minutes, uses about 100 kilocalories.
