Intermittent Fasting: Less Effective than Calorie Restriction for Weight Loss

Recent research by scientists from the University of Bath in the United Kingdom in collaboration with research institutions in the U.K., Switzerland, and Taiwan, found that intermittent fasting is not more effective than calorie restriction for weight loss. Moreover, it is even less effective in reducing body fat content.Intermittent Fasting Less Effective than Calorie Restriction for Weight Loss

For the study, the scientists recruited 36 lean, healthy adults in the U.K. between 2015 and 2018 for the study and monitored their diet and physical activity for 4 weeks. After that, they randomly assigned the participants to one of three groups.

Lead study author Prof. James Betts says: “Many people believe that diets based on fasting are especially effective for weight loss or that these diets have particular metabolic health benefits even if you don’t lose weight. But intermittent fasting is no magic bullet, and the findings of our experiment suggest that there is nothing special about fasting when compared with more traditional, standard diets people might follow.”

Intermittent Fasting May Increase the Risk of Type 2 Diabetes

A new study from Brazil suggests that trendy intermittent fasting may be the reason for increasing insulin levels and the amount of abdominal fat. It also may lead to the damage of pancreatic cells.intermittent fasting may increase the risk of diabetes

Intermittent fasting diet is a diet when a dieting person has “fast” days with a drastic restriction on calorie intake and “feast” days when one is allowed to eat anything.

For the study, a team of researchers placed healthy, adult rats on the diet for 3 months. During this period, scientists measured and monitored their insulin levels, function, body weight, and free radical levels.

At the end of the research, the rodents had lost weight according to expectations, but the distribution of their body fat changed unexpectedly — the amount of abdominal fat increased which is deeply associated with type 2 diabetes.

6 Things that Happen to Your Body when You Eat Ketogenic Diet

A ketogenic diet is a low-carb high-fat diet, which is popular among athletes and average people. This diet is based on the process called ketosis. This is a process when your body is starved of glucose for fuel and must look for fat sources instead. Normally, you fuel your body with glucose in the form of carbohydrates found in flour, grains, veggies, legumes, dairy products, and fruits. And here’s what happens to your body when you go on the ketogenic diet:ketogenic diet

  1. Your insulin levels drop.
  2. You’re less hungry during the day.
  3. You can start feeling sick.
  4. Your breath might smell.
  5. You might not be able to poop.
  6. Your body might slow down.

Brain Interprets Yo-Yo Dieting as Famine, Causing Weight Gain

A new study, published in the journal Evolution, Medicine and Public, suggests that the brain interprets irregular dieting (so-called yo-yo dieting) as short famines and signals the body to store fat for future food shortages. As a result, it leads to weight gain.yo-yo dieting

The study was executed by a team of scientists led by Prof. Andrew Higginson, of the University of Exeter, and Prof. John McNamara, of the University of Bristol, (UK). The researchers used a mathematical model of animals (birds) that knows when food is in abundance or in scarce but does not know when it happens.

Prof. Higginson says: “Surprisingly, our model predicts that the average weight gain for dieters will actually be greater than those who never diet. This happens because non-dieters learn that the food supply is reliable so there is less need for the insurance of fat stores.”

Yo-Yo Dieting Increases the Risk of Death from Heart Disease

A new study, presented at the American Heart Association’s Scientific Sessions 2016, finds that so-called yo-yo dieting (or weight cycling, when a person loses weight and regain it  fast) may increase the death risk from heart disease among senior women with normal weight.yo-yo dieting

For their study, the scientists divided 158,063 postmenopausal women into four groups: stable weight, maintained weight loss, and weight cycling. They followed the participants for 11.4 years.

Having analyzed the received data, the researchers have come to the conclusion that women of normal weight who subsequently experienced the yo-yo effect were 3.5 time more likely to die from cardiac attack compared to those women whose weight was stable.
