SIGNS YOU'RE SLACKING TOO MUCH
Your food log is inconsistent
For the three weeks, document your meals and snacks, water intake, and energy levels every day. Then compare your weekday stats with your weekend ones. Any evidence that you relax your food rules during days off? Try writing yourself a menu in advance for the full week to take out the weekend guesswork.
You don't mark up your calendar
If you don't keep track, you may not realize how much you dine out and drink on the weekends. Insert your full weekend schedule into your smartphone calendar so you know where you'll before each meal, plus when you'll need snacks. "Sometimes we Have to write these things down to get them done," Bonnie Taub-Dix, RD, founder of the blog Better Than Dieting
You feel like crap on Monday
Using your food and energy log, assess your state of Mondays. Do you start the week groggy? Bloated? Headachy? "Coming off a bender will not have you entering Monday at 100 percent, " says Holly Perkins, a certified strength specialist in Los Angeles. Then assess whether you're partying too much, skipping vital nutrients, or in need of a yoga class.
