We’ve already discussed the two most significant reasons why you see a body weight rebound after using so many diet plans in “Dealing With Metabolic Slow Down When Dieting”.
There is one more issue that can be a reason for metabolic concern and body weight rebound; malnutrition.
If you are not eating enough of the right types of foods you risk becoming deficient in a number of key vitamins and minerals and that causes changes in your metabolism and it isn’t going to operate as well as it should.
Most diets out there do cause you to become short in B vitamins and iron as well as calcium because you are so limited in your food choices. Many others have very low carbohydrate approaches as well which can cause your body to struggle when you re-introduce them into your diet.
