Stress does play a major role in affecting our bodies. It is good to hear your thyroid is normal. You are about 16kg overweight. Set a goal of losing 1-4kg a month. It is a small weight loss but over time (within a year) you will have the weight loss you desire. Exercise regularly (3+ times a week) with yoga (this releases stress). Try eating 5 small meals a day and stay within 1600-1800 calories daily range. Try to eat a Heart Healthy diet which will give you the nutrients, vitamins and minerals your body needs, lose weight slowly, and help with possibly preventing future disease states. Heart Healthy diet, which is a moderate fat diet, and a moderate fat diet means = using polyunsaturated (omega 3, corn oil, nuts, etc) fats and monounsaturated (olive oil, canola oil, peanut oil, etc) fats, no saturated fats (high fat snack foods, butter, fat spreads) and no trans fats. Eat low fat meats (chicken, fish, loin of pork) or non-meat sources (soy products, nuts), low fat vegetarian combinations (rice & beans, pasta & beans, low fat cheese & pasta), low fat and substitute dairy products (1% milk, low fat/fat free yogurts, low fat soy milk/soy yogurt), use plant oils, non trans-fat margarines, and eat a lot of fruits and vegetables. Eat daily high fiber breads and cereals (oatmeal). Suggest joining a group to help you have support to lose the weight such as Weight Watchers. Think of this as your new way of life instead of a 'diet'. Hoped this helped you.
