When your body gets ready for sleep and slows down, it also burns calories at a much slower pace. Never eat bread before bed, and make sure to avoid the butter. Choose fish or poultry for your meal instead, and include vegetables as a side dish. Even though it may sound hard, eating healthy on vacation isn't really that difficult. Other foods such as yogurt, low fat cheese, and broccoli can also help you meet the requirements for calcium. Vitamin B12 In order to absorb the benefits of B12, the intrinsic facotr must be produced by the stomach. Most elderly people suffer from a deficiency in B12 because they have a condition known as atrophic gastritis. Everyone needs the same nutrients whether they exercise or not, as well as fruits and vegetables. 6. Not enough calories Although losing weight involves calories, losing it too quickly is never safe. What you should do, is aim for 1 - 2 pounds a week. Always make sure that you are getting enough calories to keep your body operating smoothly. You should also try fresh or even dried herbs and spices to add flavor to your food. Before you eat any type of meat, be sure to trim the fat and skin off of it. 3. Avoid a lot of sugar Drinks that contain sugar are a major source of empty energy. What this means, is that the drinks contain a lot of energy that your body may not need, and it doesn't contain any vitamins or minerals. Healthy carbohydrates involve whole grain breads, whole grain pasta, brown rice, and a lot of vegetables. You should make fruits and vegetables the main aspect of your diet. Healthy cooking methods Stir frying and sauteing with olive oil or canola oil are both great methods, as you shouldn't dip your food in batter and fry it anymore. Protein Unless you happen to be a strict vegetarian, your protein intake is not normally a problem for women who eat a healthy diet. Iron A lot of women will start their pregnancy off with a bit of iron deficiency. Good sources of iron include dark leafy green vegetables and meats. Iron supplements should be avoided, as they can cause internal symptoms such as cramping, constipation, or diarrhea.
