How To Maintain An Ideal Weight

Maintaintaining an ideal body weight requires a holistic approach. A healthy diet, exercise, and stress management are the common areas that people need to focus on to stay fit and healthy.

1. Follow A Healthy Diet

A healthy diet does not mean eating only soups and salads. Speak to a nutritionist to get a customized diet plan as per your body type and make some general changes to your diet such as:

  • Choose whole grains over refined and semi-polished grains.
  • Choose high-quality proteins (dairy or poultry) for every meal. If you are a vegetarian, combine pulses, cereals (grains like millet, oats, wheat, etc.), and proteins (like soy) to get all the essential amino acids.
  • Include good fats like nuts and seeds, nut butter, and clarified butter in your diet to enhance the taste of your dishes and reap their health benefits.
  • Consume 3-4 servings of vegetables and 1-2 servings of whole fruits per day.

2. Exercise Regularly

Aim to burn calories by exercising for about 150 minutes per week. If you are a beginner, start your day with walking, followed by low-intensity strength training or yoga. Also, make sure you are physically active in some or the other way even on rest days.

3. Make Healthy Lifestyle Choices

Practice meditation and sleep well to help your body recover from daily stress. Besides maintaining a healthy diet and regular exercise, avoid smoking and alcohol consumption, to make positive changes in your lifestyle and overall health.

In Conclusion

The ideal body weight differs from person to person, based on height, age, and gender. There are several formulas you can use to calculate your ideal body weight, such as the Devine, Miller’s, or Hammond’s formula. Remember that this tool will give you a rough idea about how much you should weigh as per your height. You must always work with a doctor and dietitian, and avoid following fad or extreme calorie-deficit diets to lose weight. Also, you must make conscious diet, fitness, and lifestyle choices in day-to-day life to maintain a healthy weight. Keep in mind that this calculator cannot determine your body fat or muscle mass percentage, and it is also limited to specific age and height, irrespective of the extent of your physical fitness.
