Worst Diets for Health 2018



Are you looking for a diet for good health?  Last week we talked about “eating healthy” and reviewed 3 diets that promote good health, the Mediterranean Diet, the  DASH Diet, and the Flexitarian Diet. 
 
Mediterranean Diet - a healthy diet
Unfortunately, some people choose diets that are actually bad for their health.  Why?  Maybe they are looking for a quick weight loss fix.  Maybe they are duped into thinking a diet is healthy when it is actually bad for their health.  When the US News & World Report ranks the Best Diets for health, they have diets that fall at the bottom of their rankings.  What diets are ranked the lowest and why?  Let’s review some of these not so good for you diets and provide you with some pros and cons of these diets.  

Whole30 Diet 
This diet is popular once again.  Even though it was created in 2009, many people are currently trying the Whole30 approach.  Whole30 claims it will “change your life”.  How?  Their website claims that by eliminating certain foods from your diet, the “gut-damaging, inflammatory food groups for a full 30 days, you can take away your aches and pains, lose weight, fix digestive ailments, seasonal allergies, and chronic pain. 

What foods do you eliminate on this diet?
This diet claims that certain food including sugar, grains, dairy and legumes are the foods that negatively impact your health.

What foods does the Whole30 diet eliminate for 30 days?
No added sugar whether real or artificial.  Forget the maple syrup on your pancakes, the sweetener for your ice tea, the Diet Coke. Not even sugar less gum is allowed.
No alcohol – no wine, beer or mixed drinks for you.
No grains – so no bread, no cereal, no toast, no bagels, no quinoa, no crackers
No legumes/beans – this means no peanut butter, no kidney beans, baked beans, peas.  Forget the soy sauce – banned. 
No Dairy – no milk, yogurt, sour cream, no ice cream no cheese.  No cheese pizza for you.

What foods are permitted on this diet?
Protein foods = meat, seafood
Vegetables and some fruit
Herbs, spices and seasonings
The diet focuses on whole and unprocessed foods so you will be eating your meals at home. 
You don’t have to count calories.  Exercise is not a part of this diet plan so diet is not really a lifestyle change approach to good health.

What ranking does US News & World Report give the Whole30 diet?  The experts looked at 40 diets and ranked the Whole30 diet as 37th.    Registered Dietitian, Jessica Penner, has also evaluated the Whole30 diet on her “Smart Nutrition” website.
  • The Whole30 diet is very restrictive.  Eating out at restaurants, eating out at other people’s homes would be quite difficult on this diet.
  •  Many healthy foods are eliminated:  Any diet that eliminates food groups like dairy and grains, also eliminates the nutrients that those food groups provide.  Whole grains are foods we want to add to our diet for fiber and many trace minerals.  Dairy provides much needed calcium and vitamin D to our day.  So many Americans are deficient in vitamin D that the last thing they should do is cut more vitamin D out of their diets. Beans, peanut butter, nuts are very healthy and we should be adding more of these to our diets, not cutting back on them or eliminating them for 30 days.
  • Time-consuming – you will need to shop and prepare a lot of meals at home as the diet plan is quite restrictive.
  •  It is not a lifestyle change – it is not a plan that helps you learn how to eat healthier and exercise such as walks are mentioned by the change in diet is their key to good helath.
  •  US News & World Report noted the diet is not supported by research. 

What are the pros of this diet plan?

  • The diet does emphasize minimally processed food.
  • The diet promotes eating more fish and more vegetables.
What other diets are ranked low on the Best Diets list?
Atkins Diet is ranked number 36 out of 40 diets.  US News & World Report  states: “is not a good all-purpose diet, experts said.”

Body Reset Diet ranked #37, tying with the Whole30 Diet.  US News & World Report calls is a “gimmick” and an “unhealthy” diet for weight loss.

Keto Diet – ranked 39, almost dead last.  This diet is high-fat and low in carbs.  


So if you are looking to eat better for good health in 2018, there are many good diet plans to choose from.  There are also a number of fad diets one should avoid.  As I noted last week, healthy eating doesn’t mean giving up all the foods you like to eat, but adding some foods that promote good health like more fruits and vegetables, more whole grains, and more low-fat dairy to your day.

Best Diets for Health 2018



What does “eating healthy” mean?  What are healthy diets to follow?  Not for weight loss or weight gain, but just a healthy eating pattern?  I recently heard a person say they were on a vegetarian fast diet.  For 4 weeks they were giving up meat and all animal products including dairy.  Not really a healthy diet choice.    Another person said they were eating healthy and following the Whole30 diet.  According to the Whole30 website, food groups like grains and dairy have a negative impact on health.  US News & World Report gives the Whole30 diet a poor rating and a low ranking.  Why?  The diet is quite restrictive and excludes grain (an important food group), legumes, even peanut butter, and dairy – another important food group.  Whole grains are hugely important in our diets for fiber, trace minerals and other nutrients.  Rather than excluding whole grains, Americans should be eating more whole grains.  Dairy foods shouldn’t be restricted as dairy foods contribute calcium and vitamin D which so many Americans are lacking in their diets.  Any diet that excludes a food group, excludes nutrients that the food group provides, is not a healthy diet. 

Each year, the US News & World Report evaluates the “Best Diets”.   For 2018, they evaluated 40 popular diets and determined which ones are best for your health and fitness.  What do they look for?  They use health experts to rank diets on a number of parameters including how nutritious the diet is, how safe it is and whether the diet protects against diseases like diabetes and heart disease.  Top spots for 2018 went to the DASH diet and the Mediterranean diet.

Three diets are ranked as the “Best Diets” for 2018

    1. DASH Diet – this diet stands for Dietary Approaches to Stop Hypertension, thus the acronym, DASH. Although it was designed to help lower blood pressure, the diet is good for your health.  U.S. News & World Report notes the diet is praised for its nutritional completeness, safety, ability to control diabetes, and prevent and lower blood pressure.
a.       Nutrients – the diet emphasizes nutrients that help lower one’s blood pressure like potassium and calcium.  It encourages more fruits, vegetables, whole grains and lean protein and dairy – but low fat dairy products. 
b.      Foods to limit are red meats, and foods high in salt. 
c.       To get more guidance on the DASH diet from the National Heart, Lung, and Blood Institute, get a 20 page guide, DASH Eating Plan or a 6 page guide at Lowering Blood Pressure with DASH.  
Although the DASH diet was designed for lowering high blood pressure, it is a good overall pattern of eating healthy.
            2.        Mediterranean Diet – this diet has been written about extensively.  Many nutritionists and health experts recommend this pattern of healthy eating.
a.       Why is this diet good for your health?  The Mediterranean diet is a good diet for disease prevention – prevention of cancer and diabetes.  It is diet for healthy hearts and a healthy brain.  Basically, a healthier you.
b.      Foods to enjoy:  fruits, vegetables, olive oil, nuts, and fish.  
                                                               i.      Choose low-fat dairy – 2%, 1% or non-fat milk.  Choose low-fat yogurt.  Buy cheese that is made with low fat or skim milk like mozzarella cheese.
                                                             ii.      Whole grains – as noted in a previous blog,  so many Americans have few or no whole grains in their day.  Find a way to add whole grains to your daily food intake and to your kid’s diet.  Starting the day with oatmeal or Cheerios is a good way to add whole grains to your day.
                                                            iii.      Fruit and Vegetables – 5 A Day is a start.  More than 5 A Day is even healthier.
                                                           iv.      Nuts – add a handful of nuts a day
                                                             v.      Olive oil – buy some extra virgin olive oil and use it in cooking.
c.       Foods to cut back on: red meat, foods with added sugar and foods high in saturated fat.  

           3.  Flexitarian Diet– last year third place went to the Mind Diet and this year it is the Flexitarian Diet.  This sounds like it would be a “quack” diet, but it is actually a diet that emphasizes many healthy foods, fruits, vegetables, whole grains and plant-based protein.  It is a diet that combines vegetarian and flexibility.  This diet has been around since 2009 and was popularized by Dawn Jackson Blatner, R.D. in her book, “The Flextarian Diet: The Mostly Vegetarian Way to Lose Weight, Be Healthier, Prevent Disease and Add Years to Your Life”.  Well mostly a vegetarian diet, the flexibility comes in because you can still enjoy a burger, a steak and other meat – but on occasion. 
a.       You ADD 5 food groups to your diet:
                                                               i.      Plant-based protein = tofu, beans, lentils, peas, nuts, eggs and seeds.
                                                             ii.      Fruit – all kinds
                                                            iii.      Vegetables
                                                           iv.      Whole grains
                                                             v.      Sugar and spice – spices are super healthy so a good addition to any diet,
                                                           vi.      pastries.  Oil – olive oil
                                                          vii.      Protein – emphasis on fish and poultry
               b.      Foods to cut back on:  red meat, fried and fast food, butter, stick margarine (choose tub margarine) and foods with added sugar like sweets and soft drinks.

So rather than going on some crazy diet plan in an effort to eat healthier in 2018, choose one of the above diets to begin modeling your own eating after.  Healthy eating doesn’t mean giving up all the foods you like to eat, but adding some foods that promote good health like more fruits and vegetables, more whole grains, and more low-fat dairy to your day.

To lose weight, should you count time or calories?



Can you lose weight without dieting?  Can you eat what you want and lose weight?  New year, new goals.  If one of your goals is to take off a few pounds, do you need to count calories, go on a diet, or just watch the clock?  There is a new weight-loss strategy called, “time-restricted feeding” or TRF.  Apparently, this TRF strategy is not only for weight loss but also to help prevent diabetes, lower your blood pressure and increase your longevity. Recent articles in the Wall Street Journal, “A Diet Strategy That Counts Time, Not Calories” and other publications outlines what this strategy is and how it works.  

What is TRF?  (Time Restricted Feeding)?
With TRF, you eat what you want but not when you want.  Your eating is limited to a 12-hour period of time each day.  So, if you eat your breakfast at 7 AM, you need to finish your dinner and evening snacks by 7 PM and then not eat again until your breakfast at 7 AM.  Thus, you have a 12-hour period of “fasting”.  You choose the 12-hour time period.  
Can I eat what I want?
Yes, during the 12 hours you are eating, you can eat what you want.  You don’t have to count calories, restrict any foods.  This is not a low-carb, gluten-free diet and there are no foods to restrict, eliminate or add to your diet.  On the other hand, it doesn’t mean you can now load up on all the cake and cookies you want.  Just eat what you usually eat but during a 12-hour period each day.  


What can I drink during the 12-hour fasting period?
Water, black coffee, plain tea – no added milk, sugar, cream, etc.  

Will I lose weight on the TRF?
Probably.  Researchers have found that people who do limit their food intake to a 12-hour window and then “fast” for 12 hours each day, do consume less calories and lose weight.  Researchers, Panda and Gill, tracked the eating patterns of 8 overweight people for 21 days.  Most of these individuals consumed food over a 15-hour period or more each day.  These individuals then went on TRF and restricted their eating to a 10-hour window each day.  They lost about 4% of the body weight.  Of interest is that a year later, they were still sticking to TRF and had succeeded in keeping off the weight they lost. The WSJ quotes Dr. Panda as saying, “All of them said they slept better, and they felt more energetic throughout the day. They were actually feeling less hungry.”
Krista Varady, an Associate Professor of Nutrition at the University of Illinois, Chicago has studied an 8-hour TRF diet among 50 obese individuals over a 12-week period.  These individuals were allowed to eat between 10 AM and 6 PM each day.  They did consume less calories, about 300 less calories a day, lost an average of 7-8 pounds.  And this weight loss was not muscle loss but loss of fat.  
Are there other health benefits of TRF?
Yes.   Research indicates you can not only lose a few pounds but lower your blood pressure, have better glucose levels, and it may even slow the aging process.  Why?  They don’t know exactly but believe your body becomes more efficient at digesting foods and breaking down fat.   Dr. Shatzel, a doctor in Folsom, California recommends the TRF method not only to her overweight patients, but also to patients that need to lower blood pressure or their blood glucose levels.   Why would TRF help longevity?  Apparently, by not eating for 12 or so hours a day, you give your body, your organs time to repair and rest.  Why does TRF lower blood glucose levels?  Dr. Mirkin, a sports medicine physician, “points out that eating late at night and then going to bed causes the highest rise in blood sugar.  It’s important to move and contract your muscles after eating so that you draw excess sugar from the bloodstream.”  

How does it work each day?
The WSJ interviewed Vivian Rootness who is 66 and lives in California.  She has told her friends that she has to be done eating by 7 PM each day.  She has been restricting her food intake to 10-12 hours each day and has been doing this for five months.  She reports that she has lost 6 pounds.  Not a lot to some people, but 6 pounds she probably will be able to keep off.  She does not count calories, eats a healthy diet, enjoy some desserts and notes it really doesn’t feel like a diet to her.
Newsmax provides a suggested schedule for those interested in trying TRF:
8 AM – Breakfast
10 AM – snack if you want
1 PM – Lunch
3 PM – snack if you want
6 PM – Dinner

During fasting hours, allow yourself only water, black coffee or plain tea. 

You may want to try TRF – whether to lose weight or for other health benefits noted above.  If you want a beginner’s guide to TMF, read Time-Restricted Eating:  A Beginner’s Guide by Grant Tinsley, PhD.
