The Gym, Protein Shakes, and the Calorie Truth

Chapter 46 · Vihang Rahul Vasa

A word before you start: check with your doctor before beginning any new exercise or gym routine, and before taking protein shakes or supplements. Exercise changes plasma glucose (blood sugar), how much, and in which direction, depends on the exercise, your medicines, and you; a low during or after hard exercise is one of the risks, and some supplements can affect the kidneys or interfere with medicines. What follows is my own experience, not a programme for you to copy.

There is a popular belief that going to the gym and drinking protein shakes is a quick fix to good health. Let me share my honest perspective on this.

Going to the gym daily is, without a doubt, a wonderful ritual. It is good for you in many ways that go beyond just burning calories. It breaks the monotony of your daily routine. It gives your mind a reset. You move your body in a trained, structured manner under proper guidance. You meet new people: nice, motivated, beautiful people who are on their own health journey. You build interactions, make friends, and create a social circle that is centred around wellness rather than indulgence. The discipline of showing up every day, the energy you feel after a good workout, the sense of achievement: all of this is genuinely positive and I fully encourage it.

However, here is a simple truth that most people overlook, and it changed the way I think about health. If you run on a treadmill or cycle at a moderate pace for one full hour without a break, you will burn ~500 to ~600 calories. That sounds impressive: until you sit down for a meal afterwards.

A single 12-inch basic cheese pizza contains ~1,000 to ~1,500 calories. A small 330 ml can of soft drink adds another ~140 calories or so; a bottle, nearly double. So in one casual meal, a pizza and a cola, you have consumed roughly ~1,140 to ~1,640 calories, while your entire hour of intense exercise burned only ~500 to ~600. What went in has stayed in. The math is brutally simple and honest. (Calorie figures are illustrative: actual expenditure varies substantially with body weight, intensity, and activity, and these numbers are not universal.)

Now consider this: you eat at least four times a day: breakfast, lunch, snacks, and dinner. If you are consuming calorie-dense, processed, or sugar-loaded food at each of these meals, the total intake across the day can easily reach ~2,500 to ~3,500 calories or more. Your one hour at the gym has burnt the equivalent of barely two soft drinks. The remaining calories have stayed in your body, and over time, they are what make you obese, insulin-resistant, and with poorly controlled diabetes.

The lesson I have learned is this: weight regulation is decided by many factors, but for most of us what makes us obese is not primarily the lack of exercise: it is largely what you eat, how much you eat, how you eat, and when you eat. Exercise is important for your heart, your muscles, your mood, and your overall wellbeing. But when it comes to weight and plasma glucose (blood sugar) control, it is the kitchen that matters far more than the gym. It is more important to control what goes in than to struggle to burn what has already gone in.

As for protein shakes: they have their place, but they are not a magic solution. Some products may contain added sugars, sweeteners, or other ingredients that can spike your plasma glucose (blood sugar) without you realising it: check the nutrition label carefully. If you choose to use them, read the label carefully, consult your doctor or a qualified nutritionist, and ensure they fit within your overall dietary plan, not on top of it.

Honestly, this is purely my personal opinion based on my own experiences. But I would encourage everyone to experiment with different types of food, different forms of exercise, and different daily routines, and over time, find the regime that works best for your body, your lifestyle, and your diabetes. There is no one-size-fits-all. The best plan is the one you can sustain joyfully for life.

The Gym Is Not the Only Way

And please remember: the gym is one option, not the only option. India has gifted the world some of the most powerful forms of mindful movement, and they work beautifully for diabetes management. Yoga improves insulin sensitivity, reduces stress, and gently builds strength and flexibility. Pranayama (breathing exercises) helps calm the nervous system, which directly lowers cortisol and improves plasma glucose (blood sugar) control. Tai Chi, a Chinese practice now popular worldwide, is excellent for older adults: it improves balance, circulation, and mental clarity without straining the joints. Even daily walking, gardening, or climbing stairs counts as exercise. Find what you enjoy, what your body responds to, and what you can sustain for years. Consistency matters more than intensity. A 30-minute walk every day, after a meal, will help your diabetes control more than a 2-hour gym session once a week.
