Exercise in the Late Morning for Maximum Weight Loss Benefits

Exercising in the morning has been found to be more effective in fat burning than working out in the evening, according to a study conducted by researchers from the Karolinska Institutet in Sweden and the University of Copenhagen in Denmark. The findings, recently published in the journal PNAS, suggest that exercising in the late morning could be more beneficial for weight loss.

The scientists looked at various markers for fat metabolism and analyzed which genes were active in adipose tissue after physical activity.[0] The trial used mice due to their similar basic physiological functions with humans and being a well-established model for human physiology and metabolism, although there are also salient differences, including the fact that mice are nocturnal.[1]

The investigators found that, independent of weight loss, exercise was 3.5 times more likely to achieve a 30% reduction in liver fat compared to standard care. The team also determined that the optimal time to exercise for weight loss was the late morning.

A research published in the European Journal of Preventive Cardiology in the previous year discovered that exercising between 8am and 11am was associated with the least danger of heart disease and stroke. These findings have been reported now.[2]

“There is no current scientific agreement on the ‘best time of day’ for exercise, as what is likely more important is what is most behaviorally sound for that particular individual,” said study author Juleen Zierath from the Karolinska Institutet. “It is also unlikely that (the) time of day to perform exercise outperforms the concept of ‘calories in versus calories out’ for overall fat loss.”

It is recommended that adults engage in two-and-a-half hours per week of moderate exercise, such as cycling or walking at a fast pace, or seventy-five minutes of vigorous exercise, such as running or playing tennis.[3] A meta-analysis of 14 previous studies also confirmed that exercise leads to clinically meaningful reductions in liver fat for patients with nonalcoholic fatty liver disease.

In conclusion, the new study gives us a better understanding of how the timing of exercise impacts metabolism at a specific tissue level.[4] People who are overweight could potentially benefit from this.[5] Much discussion has taken place regarding the optimal time of day to work out in order to receive the most advantages, despite the fact that individuals are aware that they should exercise. Ultimately, it’s important to find a time that works best for you.
