i bike to work and fun. but i skip lunch and squeeze in a 3mile walk during work too.
intermittent fasting and walking is mainly what I used to lose 60+ lbs in about 5months in 2020 and kept it off since.
the secret is to find low impact cardio that you can enjoy... i don't really love walking but i can pair it with listening to podcasts, teams meetings (on iphone) for work, or calls. its hard to do teams meetings on the bike lol.
