Overview
 Principles of Weight Loss
 Macronutrients
 Meal Compositions
Success after Weight Loss Surgery
 Weight loss surgeries help you lose weight by making
it hard for you to eat as much and by making you less
hungry.
 Making poor food choices and being inactive will
make you less successful with your weight loss.
 Certain behaviors can promote weight regain




Eating frequently throughout the day
Drinking sodas, sweet teas and other calorie laden drinks
Drinking with meals
Repeatedly eating large serving sizes
Principles of Weight Loss
 To manage your weight your need to balance:
 DEPOSITS (what your eat)
Which foods should be included more frequently
 Which foods should be limited
 Everyday foods versus once-in-awhile foods


WITHDRAWALS, or how we spend or “burn” calories
 Calorie=energy currency of our body
 We need to balance our budget and spend as much as we are
taking in!
Nutrition Basics
 Three types of macronutrients provide calories
 Protein, 4 calories per gram
 Carbohydrate, 4 calories per gram
 Fat, 9 calories per gram

Alcohol does not provide nutrients but has 7 calories per gram
 Micronutrients (i.e. vitamins/minerals) do not
provide any calories
 Theoretically, 3500 calories=1 pound
Protein
 Made up of amino acids
or building block
 Animal proteins (meat,
fish, dairy, eggs)
 Plant proteins (grains,
legumes, nuts/seeds)

Do not always have all the
amino acids so may need
to be combined with other
foods
Protein
 Most important macronutrient of bariatric diet
(along with water)

Minimum 60g daily for women, 80g for men
 Needed for structure, regulating body functions, and
to provide energy

If you do not eat enough protein after surgery
May not heal as well
 Lower energy levels
 Lose more muscle and less fat
 May lose more hair

 Shoot for 50% of each meal from protein and eat
your protein first!
Fats
 Needed for energy
storage, cell signaling,
membranes, transport
and storage of fat-soluble
vitamins, and hormone
production
 Most calorically dense
component of food
Fats
 Fats are higher in calories than protein and
carbohydrates.

More than twice the calories per gram!
 They are habit forming/addictive.
 Our bodies are very efficient at storing fat.
 A significant intake can dramatically decrease your rate of
weight loss
Fats
 You do need some fat in your diet
 Essential fatty acids omega-3 and omega-6
 Fats also protect organs and bones and provide insulation
 Avoid added fats (saturated and trans fats)
 Fried foods, dressings, butter, gravies, sauces, sour cream,
cream cheese, mayo, etc.
 Healthy fats
 (olive oil, canola oil, nuts/seeds, avocado) are acceptable in
small amounts
Carbohydrates
 Main source of fuel for energy in cells
 Starches: breads, cereals, pasta, rice, crackers,
tortillas
 Fruits
 Some dairy products
Carbohydrates
 Carbs/sugars give little satiety and cause you to
become hungry again sooner.
 Foods like white bread, rice, potatoes, soft drinks,
bagels, crackers, and fruit juices are especially bad
choices.
 Choose whole grain carbohydrates in small amounts


May be problematic early in diet progression but should work for
long term
Higher fiber (wheat, bran), barley, quinoa, brown rice
Meal Composition
 Remember that at least 50% of each meal needs to be
a lean protein source
 Eat protein first

 Track your intakes
 Manage portions


occasionally measure the foods to know how much you are eating
Read food labels or nutrition facts labels
Information is per serving so think about your portion size
 Is the food a high-quality protein and how much protein does it
have?
 Is the food low calorie?
 Is the food low in fat (especially saturated and trans fat)?
 Less than 3 grams per 100 calories
 Is the food low in sugar?
 Keep to less than 12 grams per meal
 Is the food a good source of fiber?

 Track your intakes
 Use a tool to give yourself accountability long term
 Smartphone Apps
Myfitnesspal

Computer

Spending Calories
 Basal Metabolic Rate
 Over half the calories you burn are used for basic life

Breathing, heart beating, digestion, etc
 Day-to-day activities:
 Sitting, standing, cooking, housework, walking into work
 DO NOT MINIMIZE the effect of increasing the amount of
PURPOSEFUL MOVEMENT in your day to day life
 Engaging in physical activity
 Part of long term weight management to help us balance on
energy budget
 Find something you enjoy and work up to it
