The tricks to lose weight are aplenty but only a few are sustainable and long-term in nature. Aditya Chaubey, a student by profession and self-proclaimed fitness freak by choice tells us that there is no one rule that fits all when it comes to weight loss. However, there is one cardinal sin that many people (including me) indulge in while trying to lose weight and that is dieting.

You see, dieting, at its core means restriction. And no human being enjoys being placed under restrictions. Moreover, no diet is sustainable in the long run, he says. One should strive to adopt healthier eating habits and not a diet, he adds. A healthy lifestyle does demand certain sacrifices, but it is worth it in the long run! I used to feel ashamed of how I looked (at his heaviest he weighed 110 kgs or as his father would say Quinton and 10) and as a result, I was afraid to even step inside a gym, he adds.

Add to that the fact that my father is an army officer, well, I think you can understand my discomfort. So, I took up running, he explains before revealing his step-by-step approach to weight loss by making small changes in his daily life instead of resorting to a diet plan an approach that helped him shed 42 kgs and trim from 110 kgs to 68 kgs.

Running is the best form of free physical exercise, which actually burns more calories than any other form of cardio workout as it requires many different muscles to work together. It also helps burn belly fat and preserve lean body muscle.

Says Aditya, my goal was simple to be able to run a 5K in under 20 minutes. But, when I started, I could barely get run 100 metres before I was left gasping for breath. However, I was encouraged by many people to carry on, no matter what. Honestly, this was perhaps one of the best motivational bouts during those tough initial months.

Make no mistake, it didn't get any easier, I just got used to it and within 2 months I ran a full 5 Km without stopping in about 45 minutes. Granted, it was not what I wanted, but it was a start. And, now, I was ready to join a gym! During this phase, my college started and I had to leave my beautiful support system behind."

"I joined my college gym but still continued going on runs. It is the best form of exercise, it builds cardio-vascular strength, and one can do it anywhere, anytime. Below, Aditya breaks down his new weight loss workout routine.

The key is to train hard, day in and day out, each workout should demand a better you. For me, it was running on alternate days with a continuous attempt to increase the distance with each progressive day and then at the end of the week (usually Sunday) go for a long run (10 km). I used to hit the gym 5 days a week. I targeted 2 muscle groups in each session doing 4 exercises of each muscle group. Apart from this, there was my one complete rest day. No gym, no running, nothing!

I followed the principles outlined in this brilliant book, titled, "Don't Lose Your Mind, Lose Your Weight" by Dr. Rujuta Diwekar. It helped me develop healthier habits. To give you a gist:

- The key to weight loss is to consume small meals spread over the course of the whole day instead of binging and making conscious healthy choices even when you are forced to dine out. For example: I eat tandoori roti instead of butter naan, tandoori chicken instead of a rich chicken curry and pasta instead of pizza. I also make sure that the food I am consuming is not calorie-rich but is rather rich in nutrients.

- Don't leave your staple food. As far as our varied cuisine choices are concerned one should think global but eat local. In essence eat the local cuisine, dosa and Idli for Southern India, momos and Chinese in hilly areas, etc.

- Even during weight loss, it's important to meet your body's basic nutrient and energy needs. Over time, not eating enough can lead to nutrient deficiency and serious health problems. We are looking to improve our health, not sabotage it. Use a calorie tracker app to guide you through this, I personally recommend MyFitnessPal or Samsung Health.

I also followed this adage - eat breakfast like a king, lunch like a prince and dinner like a pauper to emphasise portion control.

QUICK READ: How many calories should you eat every day to lose weight?

I have been able to maintain my weight by regularly running and gymming. Although I have dialled back the frequency and intensity of my workouts, I still make sure that I indulge in at least three workout sessions and one long run every week.

I also monitor my calorie intake and check my weight daily. I didn't come this far just to gain it all back. One has to be consistent and relentless when it comes to weight loss.

Here are a few pointers which I gleaned through my journey:

1. Always be truthful to yourself. Only when you are honest with yourself about your body, will you strive to be able to change it.

2. Be consistent. If you want it bad enough you'll find a way and you'll also find the time otherwise you'll find an excuse.

3. The weighing machine is your best friend and the mirror is your most brutal critique. Check your weight weekly and at the same time, don't forget to glance in the mirror to see how your body is transforming.

4. Keep taking pictures of yourself throughout the journey, and when you feel demotivated or those extra kilos refuse to drop; look at your pictures. They will re-energise you.

5. Keep varying your exercise regime to break the monotony of the routine. Following the same pattern takes a toll on our mental state as we start getting bored with it. As a consequence, we don't put in as much effort as we can and the weight stagnates leading to immense frustration. Each workout should stimulate both your mind and body.

6. The most important step - keep a track of everything and not just calories what you eat, how much youve exercised today, how much ran...you get the gist. The devil is in the details, and it's these details that will ultimately help you analyse the ways to make your routine better. Losing weight is simple mathematics, burn more than you eat. Everyone burns some calories even while resting. This is known as Basal Metabolic Rate. There are online calculators to find one's BMR. After determining your BMR, aim to maintain a deficit of 150 calories and whatever happens, do not exceed 300 calories.

Notably, Aditya informs that during his weight loss journey, he also fulfilled his lifelong dream of becoming a certified mountaineer from the Himalayan Mountaineering Institute. Our instructors were some of the most elite climbers that the country has to offer and many of them were from Special forces. As you can imagine my physical fitness and weight loss increased dramatically during this phase. This coupled with the above strict routine helped me get in shape.
