Through sensible food and lifestyle choices, weight issues can be managed and controlled with ease. While nutrition plays a big part in weight control, a healthy approach to weight management involves a holistic view, with diet, activity, stress levels, and lifestyle at a healthy balance. There have been many diet and nutrition fads, from high fat, low carbohydrate to low fat, high carbohydrate. The most effective answer seems to be somewhere in between, with a varied and balanced diet low in sugar, alcohol and saturated fats, based on whole foods, with calorie intake matching up with calories needed for energy output. Most experts agree that weight loss results from a simple equation of reduced calorie intake and increased physical activity. A physician or nutritionist can be a great asset in developing a plan for weight loss or weight management, finding sustainable and satisfying choices that fit with a person's lifestyle.
