Asanas are certainly useful. But besides asanas, if we follow yogic guidelines in day to day living, it improves our lifestyle. These are simple tips which soon become a healthy habit.
One such habit I was introduced to many years back is reg. eating habits. Eating at 4 hour intervals and having liquids (water) in between. While initially it seemed a bit difficult to follow, it soon became a habit. The result has been - no hunger pangs in between, no overeating, etc. My weight has been constant (at most 1-2 k.g. variation over time) for the last over 20 years. There could be other reasons for this too. But I feel this is the main reason. Of course there have been exceptions to this and few times have had meals not to this schedule. But they have been very few.
Setbacks initially have been in the form of travelling or busy at work, etc. So cannot stick to this schedule. But believe me, if you want to, you can overcome these setbacks to a great extent. Started taking packed eatables with me, tried to adjust the days schedule accordingly, etc. It is practical if we give it an honest attempt.
Also generally avoided water with meals. This too has helped. Made it a habit to drink either 1/2 hour before or 1/2 hour after eating.
All such habits have to be taken practically as well. For example, if is a choice between eating at time and having unhealthy food, if proper food is not available at that time, then certainly it is better to skip the schedule. But learn the lesson and next time plan a proper meal on time.
Am sure we all start with these things, but soon find them not practical. Believe me, they are practical. Just need to put in a little extra effort. Not resort to short.cuts.
What tips have you tried and what difficulties have you faced. Talking and discussing with like minded people does help. You get a fresh perspective on things.
