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 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.
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:
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.
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.”
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.
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.
A recent study, presented at The Obesity Society‘s annual meeting, suggests that replacing your regular cooking oil with canola oil may help reduce abdominal fat in around four weeks.
One hundred one volunteers with abdominal fat or increased waist circumference participated in the study. They drank two smoothies during the day that contained specific kind of treatment oil (a conventional canola, high-oleic acid canola, high-oleic acid canola with DHA, or corn/sunflower and flax/safflower.
Participants who followed healthy diets that included canola oil had a quarter of pound (or 0.11 kg) less belly fat than they had before dieting.
