Avoid Fats Like the Plague
Despite their promising labels, low-fat foods can be deceiving in more ways than one. Often, people who choose low-fat foods over their full-fat counterparts eat way more than they should because they believe them to be so much healthier. As such, weight loss can be thwarted by uninformed consumption of these foods. Just because a product is low in fat does not mean it is low in calories. Nutritionists encourage dieters to do a little legwork and compare low-fat and full-fat products as far as calorie and fat content goes. Also, "reduced-fat" foods can carry that label without having to meet legal criteria the way that low-fat foods do, so take that into consideration when choosing products [sources: NHS, Weight-control Information Network].
Also, if the word "fat" is enough to send you screaming for the hills, you may want to reprogram your understanding of the word. Not all fats are unhealthy, and some are actually a vital part of everyone's daily diet. Polyunsaturated fats and monounsaturated fats, such as those found in nuts, fish and certain oils (olive, canola and safflower) are believed to lower your chance of cardiovascular disease. It's still a good idea to minimize consumption of heart-unhealthy trans fats found in packaged and fried foods and saturated fats, which are found in dairy products and beef.
