- The endocrine system and hormone balance predominantly control the body’s metabolism.
- Foods consumed that causes imbalance to the endocrine system leads to a slow metabolism.
- Sugar, soy and refined grains are among the culprits that disrupt metabolic activity.
My Fitness app creator and The Biggest Loser former trainer Jillian Michaels says that the endocrine system and hormone balance are the two primary things that control the body’s metabolism. So, when you consume foods that disturb these things, your metabolism gets thrown off balance as well.
Read on to learn which 3 foods are worst for your metabolism, according to the celeb coach and other nutrition experts.
Unsurprisingly, Michaels name sugar as one of the nutritional villains in an underactive metabolism. Consuming a sugary dessert causes a spike in blood sugar levels, which increases levels of cortisol and insulin hormone to balance things out. If left unchecked, it eventually causes metabolic disruption in the long run.
Michaels said that hormones “work in symphony.” With tons of them working, we need to make sure that the right ones are working for us and not against us.
In addition, sweet foods including cookies or cake, lack fiber. This is another reason why it contributes to a sluggish metabolism, according to Amanda Lemein, a Chicago-based dietitian. They are quickly broken down by the body, whereas fiber-rich foods are digested slowly. As the body fights hard to break down fiber, metabolism kicks off.
2. Processed Grains
Refined grains such as white rice or pasta and highly processed bread are also among Michael’s culprit for a slow metabolism. Having a similar effect on the body as sugar, they break down quickly and cause insulin levels to climb.
Further, refined grains consumed in excess can provide you with high levels of gluten, starch and phytic acid that hurt your metabolism, explains Josh Axe, Ancient Nutrition and DrAxe.com founder. These can be found in many packaged grain products that contain synthetic preservatives, vitamins and minerals that do not metabolize properly. In times of carb cravings, go for whole, unprocessed grains.
3. Processed Soy
Some studies indicate that excessive soy consumption negatively impacts your thyroid gland, especially if your iodine levels are already low. Other studies also revealed that conventionally grown soy which is often treated with pesticides are linked to thyroid dysfunction. Michaels recommends consuming organic and fermented soy instead.
