How long does it take to see results of a diet?

Depends on a few things, but at the end of the day you can't fake the scale or the feeling of how well your clothes fit. Just be patient and consistent.

A lot depends on how much you weigh to start and how consistent your weight loss is.

One of my coworkers has lost close to 100 pounds. I think it took about 10 pounds (usually four to five weeks) before I started to notice she was shrinking. It became more obvious as she lost 20, then 30. After about 40 pounds I realized she really was a small framed person.

She had a setback at Christmas last year she said and gained back about 20 but didn't despair and throw away all the hard work she'd done and got back on track and lost it and has continued to steadily lose weight. She's been at it about a year and a half now and has maybe 30 more pounds to go before she is where she wants to be.

2 weeks

IF you combine it with the proper exercise, perhaps a week.
