lose weight fast on bike?

[Swan]

Checking in.
My weight seems to have stuck at 180, which is beyond frustrating since at my height I'm supposed to be 110-120, but everyone has commented that I look thinner. So that's something. I hit a snag when my dad took control of groceries again.... pizza, cookies, and extra sweet tea every single night for two weeks straight, and nothing else in the house to make a healthier meal with. Ouch. And he's wondering why he's gaining weight! I wrestled with him and got back dibs on meal planning earlier this week.
Although I havent been biking as much what with all the heat and the rain, I'm trying to do at least a little activity every other day. I can't tell if it's helping or not, though, and I have to go very slowly because my back has been testy of late (probably from gaining back some weight.. darn it!!).
Trying to lose weight has been the most challenging, frustrating, and demotivational thing I've done this year, haha

Since you're struggling with back pain, have you considered a recumbent? I was an avid upright rider until my hubby's back pain reduced his riding to almost nothing. He switched to a recumbent and started riding pain-free. I soon followed (if you can't beat 'em.....) and have never looked back. I am faster now (top speed 25, cruising at 17-18 easily) and able to cycle hours without any pain whatsoever. We even toured the Pacific Coast on them last year - 1,254 miles in 24 days. And I'm not a spring chicken - 54 years young.

Don't give up - getting healthy is too important to quit!
