I am going to be blunt here. Why is everyone using time as an excuse? In fact, it should be easier to lose weight if you are truly busy, because the only thing that will make you lose weight is eating less. This whole idea about exercising to lose weight is unhelpful when the truth is that no amount of exercise is going to compensate for eating more calories than you have to. And yes, you will go to bed slightly hung…
So they are busy but it's because of a lack of time management which then plays into their inability to make good dietary choices. Being "busy" is their excuse and they make it happen by not managing their time.
Things like having to hit up starbucks before work, which wastes 10-15 minutes. Then going to grab lunch instead of bringing it from home, which wastes 45 minutes. Then they spend a large amount of time doing their outfit for the day, which wastes time in the morning. 30 minutes on social media before/after bed. Etc. These things add up to hours every day. And then "I'm too busy to eat healthy" comes out.
I say this cuz I know plenty of people who are "busy" but still manage to make great choices. I've noticed it has more to do with how people manage their time and the priorities they make throughout that time management. Time management is a skill that needs to be worked on. When one avoids managing their time well then of course they're going to be so inefficient that things get difficult.
