Do vitamin make you fat?

      These are some of the common questions that i always heard when i worked: 

Customer  A: Hi there, I am currently controlling my weight. I am thinking of taking supplements. 

                     By the way, will these supplements make me fat?

Customer B : Fish oil is a type of oil right? Will taking fish oil make me fat?

     Actually, why do we gain weight? We usually gain weight if our input , i.e food intake ( in energy form) is more than our output. If our output is more than our input, then , we loose weight. For example, lets look at Mr K:

     Mr K 's Basal energy expenditure (BEE) is 1690kcal and this is what he eat :

Breakfast : Roti canai ( 356kcal) + Teh tarik (154kcal)

Lunch : Fried rice (550kcal) + Lime juice ( 100 kcal)

Dinner : Hokkien Mee ( 950kcal ) + Fruit juice ( 250kcal)

Total : 2360kcal

Mr K's total input is 2360kcal and his BEE is 1690kcal. There is an excess of 670kcal. If he do nothing about this excess 670kcal, it may turn into fat and he may gain weight. So, if he wants to loose weight and burn off the extra calories, he need to exercise. 

Example : Jog for 30 minutes - 273kcal

               Swim for 30 minutes - 370kcal

               Aerobic dance for 30 minutes - 204kcal

               Total : 847kcal

And therefore, he will loose weight as he spend 177kcal more than what he eat.             

Do not take more than what you need if you want to loose weight

         
So, would you gain weight if you take vitamins? 
Usually, the calorie count for multivitamin or other vitamins are less than 1 kcal per tablet. So, taking vitamins according to instruction will not make you gain weight.

You are what you eat
