For a successful slimming transition, you and your doctor will have to decide whether it makes sense for you to go off thyroid pills and start taking more magnesium. It’s important to remember that your doctor will be the person you share this information with, and they need to support the process at every stage. If you are trying to lose weight in your 20s, you may still need to stay on thyroid medication to help prevent hypothyroidism.
You can also expect to get more magnesium from your diet or supplements. Some studies have found that even a few grams of magnesium can help you stay on thyroid medication, while others report that only 1 to 2 mg per day is helpful, or that this is not enough. Many people use magnesium to avoid hypothyroid symptoms, especially in those who have been off thyroid for a long time. This is most common in the early 20s, but can take up to a decade to show results.
How much magnesium do I need per day?
To lose weight effectively, you need approximately 1–2 g of magnesium per day. If you have a family history of hypothyroidism, you may require more. If you have hypothyroidism before starting thyroid pills, this often means that we need far more.
To get an idea of how much to expect to need, consult your physician. Once you go on thyroid and find out how much magnesium you need, you can start eating foods loaded with high-quality magnesium.
If you are following a low-carbohydrate, high-protein diet, it is a good idea to start eating more fat at the end of your weight loss period (in addition to the calories you are burning).
Getting enough magnesium is not an issue if you are following an active lifestyle. If you’re just eating junk food, you are likely to get enough of your recommended daily intake of magnesium, and you may find other sources helpful to support the elimination of the problem.
If you are getting a diagnosis of hypothyroidism and haven’t received your first thyroid dose in a very long time (less than five years), you may be able to start taking magnesium orally. These medications only need to be taken once per week, and are not intended to be taken multiple times a day.
Taken together, if you follow a low-carb, high-protein diet, you can be confident that you are getting enough magnesium. If for whatever reason you are not meeting the RDA, you
