walk more, it is a simple yet magical habit you can instill that could really yield positive results when it comes to fat loss

just continue to make it a habit, and increase the daily step average gradually. In the longer term you would be building a solid activity base and your metabolic health will definitely improve as well, and the fat loss will eventually come.

i personally averaged 17k steps in the month of May (as indicated by S Health), and that was with just a single running session for the whole month, the rest just being active and move around a lot. Still maintaining a BMI of ~22 despite consuming carbs like a typical Malaysian

that said, resistance training is also important. having a pair of dumbells around do help - you can work out your arms while enjoying your netflix.

the key is to build easy, sustainable habits that will benefit you in the longer run
