Diet is like the engine of a car, and exercise is like the steering wheel. If you don’t turn on the engine and you’re just sitting there yanking the steering wheel from side to side, you’re not accomplishing much. But you definitely don’t want to turn on that engine without a working steering wheel. If you’re going to turn on the engine and start going 60mph, you better have a steering wheel to make sure you’re going where you want to go.
But vegetarians may suffer high rates of chronic disease if they eat a lot of processed foods. Take India, for example, where rates of diabetes, heart disease, obesity, and stroke have increased far faster than might have been expected given its relatively small increase in per-capita meat consumption. This has been blamed in part on the apparent shift from brown rice to white and substitution of other refined carbohydrates, packaged snacks, and fast-food products for India’s traditional staples of lentils, fruits, vegetables, whole grains, nuts, and seeds.
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.

If you don’t have an established exercise routine, simply walking is the best first step toward weight loss. “Walking is a pretty good entry point for people,” says Gagliardi. This is particularly true if you have been out of the gym for a while and want to ease back into a workout routine. One small study published in The Journal of Exercise Nutrition & Biochemistry found that obese women who did a walking program for 50 to 70 minutes three days per week for 12 weeks significantly slashed their visceral fat compared to a sedentary control group.
