A fad diet… • does not meet basic guidelines for good health. • is popular for awhile before it fades away. • promises quick weight loss with little effort. • sounds too good to be true. • doesn’t give you the tools you need to help change your eating and exercise behaviors permanently.
Is this a fad diet? • Does it promise quick weight loss of 3 or more pounds weekly? • Does it tell you to never eat certain foods? • Does it suggest that you buy supplements to make up for what the diet is missing? • BE CAREFUL! Anyone can circulate a diet plan and say that it is written by a doctor or backed by a hospital.
A safe and healthy weight loss plan… • includes a registered/licensed dietitian, not a self-proclaimed nutritionist. • encourages slow weight loss of 1-2 pounds weekly. • allows you to eat foods from all the food groups- fruits, vegetables, whole grains, lean protein and low fat dairy. • encourages permanent behavior change and exercise. • There is no “best” diet.
Smart food choices • Produce • Fill your cart here! • Make this the most important section of the store. • Non-starchy vegetables are very low in calories and high in fiber. • Fresh and frozen fruit offer the same nutritional benefits. • Avoid fruit canned in heavy syrup. • Use produce as a tool to help feel fuller on fewer calories.
Smart food choices • Meat, seafood, and deli • Think lean • Beef- loin, round, and extra lean ground beef • Pork- loin • Lamb- leg • Poultry- white meat without skin • Seafood- items that are not breaded • Portion size is 3 ounces, cooked (deck of cards) • Choose cuts with little fat marbling • Trim all visible fat prior to cooking • Use low fat cooking methods- bake, grill, broil, etc.
Smart food choices • Dairy • Keep it skim or low in fat • Choose skim or fat free dairy products instead of whole fat products • Choose light, non fat yogurt • Beware of cheeses that are high in fat • Margarine/Butter debate • Look for a soft tub margarine with no trans fat • Be careful with condiments!
Smart food choices • Grains and Legumes • Choose foods made from whole grains • Use whole wheat pasta, brown rice, barley and oats • Make sure that the grain product that you choose has whole wheat listed as the first ingredient on the label • Good source of fiber • Beans are an inexpensive source of protein and fiber
Healthy eating for weight loss • Eat a variety of foods. • Do NOT skip meals. This can lead to overeating later in the day. PLAN healthy snacks into the day if needed. • Drink plenty of water and other low calorie, low sugar beverages. • Avoid liquid calories. • Limit alcohol. • Avoid fried foods. • Avoid high sugar foods.
Mindful eating behaviors • Be aware of situations that give you the urge to overeat • Watching TV, playing on the computer, reading, socializing with friends. • Take at least 20 minutes to consume each meal. • Savor and enjoy the food and chew the food well. • Distinguish between head hunger and physical hunger. • Are you eating because you need to eat to nourish your body or are you eating because you are bored, sad, lonely, nervous?
Healthful eating • If you can not pronounce the ingredients, pass it up. • Apple pie is not a fruit. • Stop eating when you are full. • A moderate diet is a healthy diet. • Choose whole foods. • Keep a food record or food diary. • Realize that you will have good days and you will have bad days.
Nutrition Guidelines for WLS • Pre-operative diet guidelines • Post-operative diet progression • Micronutrient supplementation
