How does calories make us gain/lose weight?

                                       

        3500 calories = 1 pound [of fat] gained

       

  Likewise, 3500 burned calories = 1 pound of weight loss.

  

This applies no matter who, what, when, where, how....or why!

If I ate 3500 calories today and 3500 more calories tomorrow...

and did nothing at all to burn calories, then I will have gained 2 pounds of fat (If 3500 calories = 1 pound, then 7000 calories = 2 pounds). 

Whether the pound(s) gained are fat pounds or muscle pounds depends on the food that was eaten from the start (i.e. nutritious food or non nutritious food).

On the flip side...

3500 burned calories = 1 pound of weight loss. 7000 burned calories = 2 pounds of weight loss. Basically, follow the theory that when that 3500 calories settle, then a pound is gained. 

What stops calories from settling? 

Use of calories as energy stops calories from settling/accumulating to that 3500 = 1 pound mark. Things that burn calories (use energy) are:

walking   running    thinking    talking    working out    sports   reading   playing

and many many more things similar

Blog: Fat under Our Skin Theory

                          Part I:  (Fat cells)

You have skin, fat, muscle and then bone. Notice how the fat sits between your skin and your muscle.The more fat you have, the less visible your muscles are. 

How your fat cells grow/shrink depending on what you eat:

Our bodies have billions of fat cells. When we gain weight, we gain size in "each" fat cell in a sense. When we lose weight, we lose size in "each" fat cell. 

Think of a single fat cell as a lower case "o". 

Let's say that this is the size of a fat cell in an average person that is not too far overweight.

Now, look at a person who is, for example, 150

pounds over weight. Think of "each" of their fat cells to have grown from a lower case "o" to 

an upper case "O".        

Keep in mind that each fat cell grows at the same time. 

The more we eat foods that have no real nutritional 

value, the more "each" fat cell grows. The more we eat 

healthy food, the more "each" fat cell "shrinks" back to 

it's normal size (or even smaller).

When we go overboard by eating foods that are of no real nutritional value, we take the chance of causing individual fat cells to get so huge that the old (maximum capacity fat cells) create new fat cells causing excess fat and "blubber".
