INTERMITTENT FASTING AND FAT LOSS

Here’s the latest on breakfast vs no breakfast, yogurt vs eggs:

Greater fat tissue mobilization can be achieved through early-day fasting in comparison to consuming a low-carbohydrate breakfast or a Mediterranean-style breakfast, shows a small study that explored the short-term effects of intermittent fasting by lean people.

The study also found that consumption of a low-carbohydrate breakfast results in longer suppression of hunger compared to a Mediterranean breakfast. The study was led by Dimitrios Tsilingiris, MD, Ph.D. and presented the findings recently at the virtual meeting of the European Association for the Study of Diabetes (EASD).

“Through fasting intervals as short as those achievable through a 16:8 restricted feeding scheme, a substantially and measurably increased fat tissue mobilization ― as indexed by increased ketone body production ― may occur,” said Tsilingiris, reporting the main finding.

He added that for most ketogenic diets, time is needed for the switch toward fat burning, but the findings from this study could provide support for an “on-demand” application of this strategy.

“The quite high subjective hunger scores at the end of the fasting sessions should also be taken into account, since the feeling of hunger may obviously drive the subsequent caloric quantity intake,” Tsilingiris, formerly of Laiko General Hospital, Athens, Greece, but now based at the University Hospital Heidelberg, in Germany, pointed out.

Anne-Marie Aas, Ph.D., clinical dietitian and associate professor at Oslo University Hospital, Oslo, Norway, was session moderator. “The findings from this Greek study in healthy people is interesting but not surprising, since a prolonged fast would naturally prolong the time the metabolism yields energy from fat stores,” she said. “The most interesting finding is perhaps that fasting resulted in increased hunger, while the low-carb breakfast suppressed appetite for longer than the typical Mediterranean breakfast,” she said.

“This is in line with an earlier study from the same group [as reported from EASD 2018] showing that morning-time carbohydrate restriction resulted in greater weight loss in obese individuals over a 2-month period,” she noted.

The First Study of Short-Term “On-Demand” Intermittent Fasting Tsilingiris explained that evidence in the literature suggests that intermittent fasting is associated with numerous health benefits. The term refers to a relatively heterogeneous group of dietary habits that commonly include prolonged fasting intervals within a month (periodic fasting), a week (5:2, alternate day fasting), or a day (time-restricted feeding, 16:8). In theory, intermittent fasting leads to loss of fat tissue through a metabolic milieu that promotes fat mobilization, he said.

“To our knowledge,” he said, “this hypothesis regarding the shortest-term application of intermittent fasting ― that is, the increasingly popular 16:8 ― has not been put to the test until now.”
