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.
