Using the wrong plastic dishes.
The exposure to certain chemicals can affect our metabolism, according to researches published in Critical Reviews in Food Science and Nutrition and the International Journal of Obesity. These researches found the connection between weight gain and the exposure to certain chemicals that disrupt the body’s endocrine system, such as Bisphenol A (in certain plastic utensils) and PBDE (in clothes, mattresses etc). Pesticides who enter our body through food can also affect the creation and metabolism of hormones.
What to do? Make sure to use Bisphenol A free plastic dishes and utensils, and avoid wearing clothes that contain PBDE. Moreover, try to consume organic fruits and vegetables.
Not Eating Enough Protein
Protein consumption is one of the more important ways through which you can increase your metabolism. Protein has the largest thermal effect, which means that in order to digest it our body invests the largest amount of energy – approximately 25% – 30% in comparison to only 5%-10% required to digest carbs or 0%-3% required to digest fat.
A protein rich diet increases muscle mass hence increases the metabolism during rest, since muscle burns seven times more calories than fat.
What to do? In order to improve your metabolism make sure protein constitute approximately 25%-30% of your daily calorie intake. Eat both protein that comes from animals (fish, turkey, egg yolk etc.) as well as from vegetables (beans, chickpeas, quinoa etc.)
