Are You Losing Body Fat Or Water?

“I tried that diet and lost 8 pounds in the first week!” 

“I’ve gained three pounds in one day! It must have been the
cookie I ate or maybe the mashed potatoes!” 

Stepping on the scale can become an anxiety filled event that
leaves people wondering where they went wrong when the numbers
don’t go in the right direction. This leads to panic and
usually ends with blaming a particular food item that really
wasn’t the culprit. Everyone who has been on a journey to lose
weight has been there before. Even though you are following
your plan and exercising regularly the number may go up 1-2
pounds or even up to 3-4 pounds creating unnecessary guilt that
we have failed somehow. If it’s not always food that makes our
weight creep up then what is it that causes these fluctuations
on the scale? 

When trying to lose weight the scale often becomes the only
measurement of success and this makes it difficult to remember
that every time we step on a scale it is measuring every part
of our physical being at that moment in time, which means it
measures our fat, muscles, organs, tissue and water weight.
Body fat is not the only thing being measured. While organs and
tissue don’t change much; fat, muscle, and water do change which
can result in fluctuating numbers on the scale. 

Water weight can affect your total weight anywhere from 1-10
pounds and sometimes even more. It is important to understand
what kinds of dietary factors can make these fluid shifts
happen. To start, many of the high protein, low carbohydrate
diets can cause a dramatic shift in your water weight. This is
because as you cut back carbohydrate intake your body starts
breaking down the stored carbohydrates (glycogen) to use as
energy, and this breakdown causes the body to excrete large
amounts of water. Once the body begins to use stored fat for
energy, weight loss slows. This is the reason why most people
lose a significant amount of weight right away on a low carb,
high protein diet. Extreme low carb, high protein diets can
potentially lead to dehydration because of this significant
fluid loss.
 
When a person following a low carb plan eats a
carbohydrate-rich food they can easily gain 1-3 pounds.
However, this weight gain can be misleading because it is
usually your body replenishing the fluid it lost and not gained
fat. This 3 pound fluctuation becomes frustrating for many
people and they end up yo-yoing back and forth with fluid
weight thinking that it must be the half cup of rice they had
the night before that caused them to gain that 3 pounds when in
fact eating the rice just allowed them to regain some of the
fluid they had lost from following a strict low carb plan. The
fact is carbohydrates do not affect your weight quite that
simply. Excess carbohydrates can strongly stimulate insulin
production, which promotes fat deposition and increases
appetite. This kind of weight gain will happen gradually, not
dramatically overnight. 

Sodium is another dietary component that can lead to fluid
gain. Sodium can cause the body to retain fluid, leading to
these frustrating daily weight fluctuations. Some people are
more sensitive to sodium than others. Watch your diet and see
if your weight gain corresponds with a high sodium meal the day
before. For example, eating out in restaurants can often
increase your sodium intake significantly. 

The best way to tell if you are retaining fluid is to pay
attention to your body. If you get indentations on your ankles
and lower legs from your socks then you are retaining fluid. If
you wear rings and they become tight and leave an imprint in
your fingers when you take them off then you also retaining
fluid. Any kind of puffiness in your skin is a good indication
of water weight. 

The bottom line is that it takes 3500 calories to gain or lose
1 pound of body fat. This equates to an extra 500 calories a
day over 7 days to gain a pound. This means if you gained 3
pounds in one day you can chalk it up to fluid weight otherwise
you would have had to consume 10,500 extra calories that day
which is not likely! True weight gain happens gradually and
likewise we lose it gradually. Check your weight weekly instead
of daily and look for overall trends. If you are seeing dramatic
daily changes in your weight, it is likely the ever-changing
shifts of our body’s water weight.
