Very low levels of thyroid hormone usually indicate an autoimmune reaction to the thyroid gland itself. This means you’ll have to take thyroid hormone supplements orally, usually the stable form T4 (Levaxin), which your doctor can prescribe for you. Your body will transform this into the active T3 hormone when necessary. The supplement dose should be adjusted so that you reach normal hormone levels (TSH, T3, T4) and sufficiently alleviate symptoms – though a few people feel best when keeping TSH slightly below normal.
When you drink liquid carbs, like the sugar in soda, your body doesn't register them the same way as, say, a piece of bread, according to a review of studies published in Current Opinion in Clinical Nutrition & Metabolic Care. That means, even though you're taking in calories, your fullness cues aren't likely to signal that you're satisfied once you finish off a can. And that can lead to consuming more overall.
Before you start the meal plan, make a pot of the Veggie Soup. Make 2 servings of Overnight Oats, so they can soak in the fridge. It’s also super helpful to prep your veggie snacks—make 4 bags filled with baby carrots and sugar snap peas, and 3 bags filled with broccoli and cauliflower, for alternate days. And if you really want to get ahead, you could also grill the chicken breasts and cook the quinoa and brown rice in advance.
