What do we mean by weight gain?

Weight gain simply means that there is an actual increase in your body weight.

The most common reasons for increasing your body weight are:

  • Increase in the bulk of your muscles:

As you exercise, your muscle mass increases in relation to your body fat. The increase in muscle mass increases your body weight. It is a very healthy way of weight gain.

  • Amount of fat in various parts of your body:

As age advances  and due to lack of exercise, there is increase in your body fat in relation to your muscle mass. Such increase in body fat is not seen as a healthy way of weight gain

  • Excess fluid causing water retention:

Medical conditions like heart failure, liver failure and kidney failure cause collection of excess fluid and water retention – not a healthy way of weight gain.


One pound of human fat tissue contains 3,500 Calories. So to lose a pound of weight over a week, it means that you have to reduce your food intake by 500 calories a day. Some examples of a 500 calorie food are:

  • Big Mac
  • 4 slices of Bacon
  • Frappuccino with cream
  • Subway 6″ Ham sandwich
  • Full cheese Burger
  • 2 Snickers


At the same time if we take an extra 500 calories every day over a week, we add 3500 extra calories. We will gain a pound in weight!

This significantly increases the risk of lower back pain

What is BMI?

BMI stands for Body Mass Index. It is a standard measure used to measure obesity all over the world.


Your Body weight in kilograms is divided by your weight by your height in metres




To make it easy, there is a chart below that you can use to look up your BMI for your weight and height.


It will also show if you are in the ideal weight, overweight or obesity category.


BMI Chart for Back pain to calculate your ideal weight, overweight and obesity

BMI Chart gives you a quick idea of where you are on the chart. This Body Mass Index Chart can be used by all adults of any age, weight and height.


It gives you the normal range for your weight and height. The weight is given in pounds on the left side and in kilograms on the right side (see chart above).  The height is given in centimeters and feet below the chart.


If your BMI is:

18 – 25 – Shows a Normal & Healthy weight

25 – 30 – Overweight at risk of Back problems

> 30  – Obesity – Back pain & Degeneration

How does Weight gain affect your Back pain?

      • less than 125 lbs
      • <9 stones

As you can see here, our spine is this central support for our body to provide strength, flexibility and movement.


Our spine has three natural curves that are in balance to distribute your body weight. This provides perfect alignment with the strong and flexible muscles in your back.


During the later years there is a gradual weight increase and the shape of these natural curves are altered. It is important to note that any increase in weight in the belly fat, adds 10 times the weight on your back.

Can belly fat make your back hurt?

About Belly Fat:

Belly fat causes potbelly and this changes the curvature of your back. Belly fat pulls your spine forward causing stress on the bones, muscles, ligaments and the soft cushions (discs).


Belly fat that sticks out farther away from the spine can cause severe strain on joints of your back.


This can lead to osteoarthritis of your spine reports a study from the University Hospital Zurich in Switzerland.


“Further your belly sticks out greater your backpain”

What are the other problems with weight gain other than back pain?

When your body weight increases, the spine becomes tilted and develops an unnatural curve. There is more stress on the small joints of your spine call the ‘facet joints’.


The chemicals released from the excess body fat, damages the lining of these facet joints leading to inflammation and later arthritis.


Further increase in bodyweight squeezes the soft tissue cushions (discs) between the bones of your spine.

Overweight and obesity can cause the disc to rupture. This causes a ‘Disc Prolapse’ or a ‘Bulging Disc’.


‘Bulging Disc’ cause pressure on the spinal nerves going to the leg

This leads to back pain and leg pain called sciatica

How to lose weight during an episode of back pain?

Take small tiny steps and be comfortable in what you are doing.

Unhealthy eating habits are binge eating, eating at frequent intervals, comfort foods and eating out regularly.

A food diary is very useful in noting down these unhealthy eating habits.
