Common Diets • The Atkins Diet (Low Carb / High Fat) • The South Beach Diet (Good Carb / Fat) • Slim Fast (Meal Replacements) • The Zone Diet (Balanced Diet) • Weight Watchers (Low Calorie / Low Fat)
Atkins Diet (Low Carb / High Protein/Fat) • Advantages: • Ability to eat food normally disallowed on Low-Fat diets (i.e. Meat, Cream, Cheese.) • Disadvantages: • Vegetarian Unfriendly. • Low amounts of dietary fiber (found in complex carbohydrates) can contribute to constipation or diarrhea. • Doesn’t comply with American Heart Association guidelines for a healthy heart.
Food Choices on Atkins • Do Eat: Red meat, eggs, cheese, butter, nuts. • Don’t Eat: Potatoes, rice, pasta, bread, sweets, alcohol and caffeine. • The Atkins diet also holds a heavy emphasis on nutritional supplements and exercise, as well as regular testing to monitor levels of cholesterol, blood pressure and triglycerides.
South Beach Diet(Good Carb / Good Fat) • What is it? • A diet that emphasizes eating only the right fats and the right carbohydrates after going through 3 phases – The best of both worlds. • How does it work? • Complex carbohydrates are slow in releasing sugar to the bloodstream, thus leaving you feeling satisfied and energetic for longer periods of time.
South Beach Diet(Good Carb / Good Fat) • Advantages: • Based on the Glycemic Index, which most nutritionists consider a valid tool in composing a diet plan. • Gradual weight loss after Phase 1. A plan intended to be used for life. • Takes heart health into consideration. • Disadvantages: • Phase 1 of 3 call for drastic carbohydrate restriction, causing high dropout rates and a serious test of willpower. • Promises of losing 8-13 Lbs. in the first two weeks is unhealthy, and is likely to be regained once Phase 1 ends and less restrictive eating continues.
South Beach Food Choices • The South Beach Diet relies on the Glycemic Index. After phase 1, the diet calls for foods low on the Glycemic Index contain complex carbohydrates. The following foods are recommended: • Lean meat, chicken, fish, eggs, low-fat cheese, some nuts and olive oil the “good fats”.
Slim Fast(Meal Replacements) • What is it? • Drinking two shakes a day to replace two meals, followed by one regular meal. • How does it work? • Creating a calorie deficit by reducing calorie intake to nearly 1200 kcal's per day.
Slim Fast(Meal Replacements) • Advantages: • Quick and convenient. • Drinks designed to make you feel full. • Flexible, hardly any dietary restrictions. • Disadvantages: • Not necessarily great-tasting. • Hard to stick with. Repetitive. • Low on Protein (encourages muscle loss – most weight loss will come from muscle).
Slim Fast Food Options • Slim Fast emphasizes a “sensible” dinner to go along with one replaced meal of a shake. • Slim Fast allows for only 1200 calories a day. This is very dangerous, and this diet is not recommended. • No foods are “forbidden” - but the following are recommended: • Lean meat – such as poultry or fish; • Vegetables; • Fruits; • Legumes – such as potatoes.
The Zone Diet (Balanced Ratios) • What is it? • A diet containing 40% carbohydrates, 30% proteins, and 30% fats lowers insulin levels and controls hunger. • How does it work? • Using a 40-30-30 ratio, the goal is to find the “zone” where life in general is just better. The natural “buzz.”
The Zone Diet (Balanced Ratios) • Advantages: • Non-Restrictive in food choices. • If you find “the zone,” weight loss occurs gradually and life in general is better. • Balances insulin and glucagon. • Disadvantages: • Hard to calculate and find “the zone.” • May not suit the energy needs of a typical college student.
Food Choices on The Zone Diet • Fairly non-restrictive. However, the daily caloric intake for this diet is determined by your protein requirements - which can lead to incredibly low daily caloric intake.
Weight Watchers(Low Calorie / Low Fat) • What is it? • Weight Watchers is a sustainable (2 pounds per week) diet based on changing eating habits with a life-long goal of nutritious eating. • How does it work? • Weight Watchers depends on a support system for their dieters. • Dieters are guided through a point system that helps them determine what they should or shouldn’t be eating, • Through fundamentally sound eating, weight is lost.
Weight Watchers(Low Calorie / Low Fat) • Advantages: • Ongoing support and advice. • Steady, long-term weight loss. • Disadvantages: • Cost of classes ($10-15 per class, plus other fees). • Point/Calorie system does not take into account other nutritional considerations. • The group meetings can be daunting or threatening to some.
Food Choices on Weight Watchers • All major food groups included. • Weight watchers offers a wide variety of food groups – so cravings tend to be less of an issue than with other diets. • Good for Vegetarians.
Do Diets Really Work? YES! All diets work They stop people from eating so much At the end of the day
At the end of the day • Pick a diet that best suits your goals, and go in with a realistic frame of mind. • What will determine weight loss is the ratio of calories intake vs. calories burned.
Other Diet Tips • When following a diet, allow “cheat meals” at least once a week as to prevent dropout. What matters at the end of the week is if more calories come in than are used… A surplus one day won’t kill you! • Examine the reasons for overeating: To clean your plate? Stressed? Angry? • Do not eat until full - sometimes the best exercise is pushing yourself away from a plate. • Do not forget the importance of water and a multivitamin.
