Testimonials & Success Stories


From Jim A., 47 an active 47-year-old who quit consuming sugar and lost 50 lbs:

"Hello Dr. Eisenberg,

About me:

Age 47, Married with 3 children. Physical Education Teacher (25 years), Head Boys Varsity Lacrosse Coach, Head JV Football Coach

The Book:

I had not gone to the Doctors in a while, and went in December. My weight was 271. I went to Fairport Pediatrics with my children soon after and saw your book. Bought it/read it.

Current weight: 220

I changed my sugar intake on Dec 24th, 2015.  Wife was making her famous Holiday cookies.  I decided to treat sugar like cigarettes (if I smoked- I have never smoked, but if I did, cold turkey would be the answer).  I "quit" sugar.

By March 17th (St Patricks Day, I had dropped 50 pounds).

I have always been active.  College Football player.  As a PE teacher, I am always moving.  I did increase my exercise amount and intensity in December.

25 years of teaching.  I gained 2 pounds a year.  50 pound wt gain. I am?/was? addicted to sugar. Ice cream at night, candy at school/home. I feel quitting sugar is more difficult than drugs. They don't have holidays that celebrate through drug use (like we do candy). They don't have cigarettes in a dish at every desk where I work (like we do candy).

We are surrounded by sugar and I just said no.

I wanted to see if I could be "normal" and have sugar last week in the form of ice cream- cravings all came back.  Honestly, for me, it is a drug.

Thank you for the book and the knowledge it contains.

Sugar is addictive (life can feel "not normal" without it). Sugar is accepted (As a teacher, I am to immediately address a student if they are seen smoking/drugging/drinking- but if I see a student morbidly obese I would not tell them to put the soda down).

I will try and send pictures of before and after.

Thanks for everything"


From Judy B., a 52-year-old, who cut out sugar to try and lose weight.

I used to eat lots of carbs (bread and pasta) and daily sweets in the form of sweet breads, cookies, ice cream, yogurt, granola bars, and chocolate milk. It wasn’t stress eating — it was simply the diet I was raised on, where dunking two or three biscotti in a cup of coffee was a very natural breakfast. 

To start, I cut sugar substantially, cold turkey, by eliminating all desserts. I kept eating yogurt with added sugar and went from sweet-and-salty granola bars to Kashi granola bars (with only 4 grams of sugar).

When I craved sweets, I ate fruit — mostly fresh fruit but sometimes dried dates or figs (in moderation, since the natural sugar content is still high). If I wanted something chocolaty, I would have a glass of skim milk with Ovaltine chocolate powder. It was rare that I craved actual desserts (cookies, cakes, etc.).

I eat a hardboiled egg and a piece of fruit, or cooked oatmeal with walnuts and raisins, for breakfast. No syrups or honey. I try to keep sweets out of the house. When I do bake, I actually don’t eat a single bite because I know if I eat one cookie I will want more.

I dropped more than 10 pounds in six months. The weight loss made me feel better mentally; I started at 154 pounds and got down to about 142 in six months.

Next, I cut out all fried foods and bread, and cut out more sugar by eating only plain yogurt, natural peanut butter and cutting down on my milk intake. With that change, and starting an exercise routine, I’m down to 130 pounds, and I’m OK with that (I’m 5’ 2”).

On the occasions when there is a birthday in the office and I take a small piece of cake to be social, I actually feel nauseous after eating even small quantities of added sugar. Even as little as ½ teaspoon of jelly on an English muffin with peanut butter brings on nausea.

Sugar setbacks have been minimal. I don’t feel that I’m missing anything meaningful to me. I feel like a different person, with a sense of both physical and mental accomplishment. More control over my quality of life as I age — and a reduced risk of diabetes — is very important to me.


From David L., a 55-year-old who cut down on sugar to improve his cholesterol levels.

Ever since I was a kid, I felt lethargic when I woke up. Like a lot of kids, I drank a fair amount of juice and soda, and ate occasional desserts.

As an adult, I was pretty careful with what I ate, and I exercised, but I needed to take naps. I drank coffee to wake up, then I’d have a donut and juice when I started working, but I wouldn’t have a lot of energy. If I ate lunch, I would often take a short nap in the afternoon.

Eventually I was diagnosed with high cholesterol. Instead of doctor-recommended statins, I started eating flavored yogurt and lots of fruit. I cut down on meat, butter, milk, saturated fat, and I exercised even more, but my bad cholesterol actually went up.

In 2013, I learned about what sugar does to the body. So I eliminated all fruit juices, all soda, and sweets. Three to four days a week, I eliminated all added sugar. I went through my house and threw out fruit juices and cookies, replacing the calories with nuts, which helped give me a sense of fullness when I had sugar cravings. The first two or three weeks are brutal. The cravings are exceptionally strong — you constantly think about and desire sugar.

For the first thirty days, I had more energy but it was a fidgety, irritable energy. Then that started declining. After three months, the napping and lethargy were mostly gone. The cravings faded to once or twice a week and they decreased in intensity. After three months I had consistently more energy.

During that time I broke down once or twice a week. When I did break down, I would eat an ice cream sundae, and then I wouldn't get a good night's sleep. I would wake up lethargic, just like I used to.

After a year, the cravings were less frequent, but still there. Now, about a year and a half after starting, the cravings are gone. I can have an occasional dessert, and I’m fine. I eat more red meat, cream, and butter than ever.

My bad cholesterol is down significantly, and my good cholesterol is up. Now, I have more energy, I'm much more productive during the day, and my strength has significantly increased.


From Jacob W., a 17-year-old who, despite exercise and a low-fat diet, still couldn't lose weight.

During my senior year of high school, I made a conscious effort to reduce the amounts of fat (fast food, potato chips, etc.) in my diet, so I was confused as to why I wasn’t losing any weight. I played sports, did martial arts, cycled, and stayed fairly active; all things that healthy people do. But for some reason, I was still tired all the time, and would always find that my weight was staying right where it was.

Then, I cut soda and fruit juice out of my diet, replacing soda with black coffee and fruit juice with water. I switched from white bread with sugar added to all-natural whole grain bread. I reduced the sugar in my diet, instead of the fat.

The next year of my life, my freshman year of college, was a big turning point for me. I dropped about 30 lbs, and had to buy new jeans (a price I was happy to pay for a healthier body). I had the energy I needed to balance school work with outside work, while actively maintaining a busy social life; all typical “first year of college” things.

Adhering to a diet that kept sugar low and healthy fats high changed my body, and changed the way I feel about myself. I think that eliminating sugar from one’s diet is a big, scary step, but ultimately, one worth taking.
