1: “Bananas are fattening.” They are actually low in fat. There is only 0.5 grams of fat and 95 calories in a banana.

2: "Eggs raise cholesterol." Saturated and trans fats are more likely to raise heart disease risk, not dietary cholesterol. 

3. “A glass of warm milk will help you sleep.” Milk does contain the nap-inducing amino acid tryptophan, but only in trace amounts. 

4. “Preacher curls work lower biceps.” You cannot contract the lower portion of your bicep without working the whole bicep.

5. “More hours in the gym means better results.” Overtraining will break down muscle tissue and stop muscle growth.

6. “Something with a fat free label is good for you." Milk, yoghurt, cheese etc. will have all or most of their natural fat removed and replaced with sugar, salt and artificial sweeteners.
