Eating healthy and exercising doesn't give you an all access pass to eat anything you want. 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. When you use it with cooking, you should heat it on low to medium temperatures, making sure to avoid high heat. 3. Butter Butter is one food that has been around for many, many years. Butter tastes good, and offers sources of Vitamin A and other fat soluble vitamins such as E, K, and even D. Butter is also made from natural ingredients and not chemically or artificially processed. Some meals and some days will be higher in fat than others. Even high fat meals can be kept in line with healthy eating as long as you balance those days accordingly. The average fat intake over the course of weeks and months is important, not the fat intake of every meal and food you consume. Younger adults and high active adults who have higher calorie needs can probably eat a little more fat. It's easier than ever these days to request a low fat or vegetarian meal on airplane flights. If you choose to instead drive to your destination, the quest to find healthy food can get a bit more complicated. Rather than simply relying on greasy foods for nutrition, pack some nutritious foods in a cooler full of ice packs. Half of the dessert will equal half of the calories. - When you choose a soup, remember that cream based soups are higher in fat and calories than other soups.

Always eat breakfast Even though you may think you aren't hungry, you need to eat something. Skipping breakfast makes it harder to maintain the proper blood and sugar levels during the day, so you should always eat something. Carry a snack Keeping some protein rich snacks in your car, office, or pocket book will help you avoid blood sugar level dips, the accompanying mood swings, and the fatigue.
