A high-energy breakfast promotes weight loss in type 2 diabetes patients

Eating a high-energy breakfast promotes weight loss, improves diabetes and decreases the need for insulin, according to new research by Israel’s Ministry of Health.

The study’s lead author, Daniela Jakubowicz of Tel Aviv University, said: ‘This study shows that, in obese insulin-treated type 2 diabetes patients, a diet with three meals per day, consisting of a big breakfast, average lunch and small dinner, had many rapid and positive effects compared to the traditional diet with six small meals evenly distributed throughout the day: better weight loss, less hunger and better diabetes control while using less insulin.’

‘The hour of the day – when you eat and how frequently you eat – is more important than what you eat and how many calories you eat. Our body metabolism changes throughout the day. A slice of bread consumed at breakfast leads to a lower glucose response and is less fattening than an identical slice of bread consumed in the evening.’

Jakubowicz and her colleagues studied 11 women and 18 men (with an average age of 69) who had obesity and type 2 diabetes, being treated with insulin. The patients were randomly assigned to consume one of two different weight-loss diets, which contained an equal number of daily calories, for three months. One group (on the ‘Bdiet’) ate three meals: a large breakfast, a medium-sized lunch and a small dinner. The second group (on the ‘6Mdiet’) ate the traditional diet for diabetes and weight loss: six small meals evenly spaced throughout the day, including three snacks.

Overall glucose levels and glucose spikes were measured for 14 days at baseline, during the first two weeks on diet, and at the end of the study by continuous glucose monitoring. Glucose levels were tested every two weeks and insulin dosage was adjusted as needed.

At three months, while the Bdiet group lost 11 pounds and the 6Mdiet group gained three pounds.

Fasting glucose levels decreased 54 mg/dl in the Bdiet group but only 23 mg/dl in the 6Mdiet group. The Bdiet group needed significantly less insulin (-20.5 units/day, from 54.7 to 34.8) while the 6Mdiet group needed more insulin (+2.2 units/day, from 67.8 to 70).

The researchers found a significant reduction of overall glycemia after as little as 14 days on Bdiet, when the participant had almost the same weight as at baseline. This finding suggests that even before weight loss, the change in the meal timing itself has a beneficial effect on glucose balance that is further improved by the important weight loss found in the 3M diet.

    Great breakfast. In July of 2017. it was discovered that I got type 2 diabetes, By the end of the July month. I was given a prescription for the Metformin, I stated with the some diet and followed it completely for several weeks but was unable to get my blood sugar below 140, Without results to how for my hard work. I really panicked and called my doctor. His response?? Deal with it yourself, I started to feel that something wasn’t right and do my own research, Then I found Lisa’s great blog (google ” How I freed myself from diabetes ” ) .. I read it from cover to cover and I started with the diet and by the next week. my blood sugar was 100, Since then. I get a fasting reading between the mid 70s and 80s, My doctor was very surprised at the results that. the next week. he took me off the Metformin drug, I lost 16 pounds in my first month and lost more than 3+ inches off my waist and I’m able to work out twice a day while still having lots of energy. The truth is that we can get off the drugs and help myself by trying natural methods..

  • Thanks for sharing this information with have great impact on health, it great.

    The research seems to confirm the dietary advice of breakfast like a king…. My own experience is that extending the overnight fast also assists weight loss and results in more uniform energy levels throughout the day.

    Breakfast is not necessary for weightloss It’s easy to go without until 1-2 pm and consume energy until the time one gets ready to go to bed. The solution is weightloss for every person is to consume less and move more, why? because fat cells will shrink and we will go from 80 billion fat cells to 40 billion without noticing because we breathe out the weight lost from eating less and moving more. this reverses T2D.
