Get all that? Basically, the differences between groups were minimal. Yes, the low-fat group dropped their daily fat intake and the low-carb group dropped their daily carb intake. But both groups ended up taking in 500 to 600 calories less per day than they had before, and both lost the same average amount of weight (12 pounds) over the course of a year. Those genetic and physical makeups didn’t result in any differences either. The only measure that was different was that the LDL (low density lipoprotein) was significantly lower in the low-fat group, and the HDL (high density lipoprotein) was significantly higher in the low-carb group.
To start off, aim to do ab work 3 or 4 times a week on non-consecutive days with at least 24 hours of rest in between sessions, says Gagliardi. During those sessions, you can start with simpler moves like crunches, bicycle crunches, and planks. Even though you may only be directly targeting your abs 3 or 4 times a week, you should still be activating your core (aka, tightening your ab muscles) in every workout you do, says Gagliardi.
Cons: In our experience, capping your calories low will probably mean a lot of internal strife and stress. Plus, we’re big fans of enjoying food instead of fearing it, and 800 calories doesn’t leave much room for satisfied taste buds. Lastly, if you’re currently eating double to triple this amount of food, dropping to a daily caloric intake this low can tank your metabolism and actually slow weight loss more than switching to one of these other diets might. (Curious? Here’s why starving yourself won’t help you lose weight.)
You know that recording what you consume is a good way to keep your weight in check, but Brittany Hicks, who dropped 110 pounds in college, didn't only write down what she ate—she also wrote down why she was eating it. "I realized I'd been using food to cope with stress," she says. "Just noticing that helped me do it less." Make sure you're not making these food journal mistakes so you can reap the rewards of eating and jotting, too.
"It’s easy to become impatient and frustrated when you’re trying to lose weight and haven’t seen the results yet. But be realistic – you won’t see the affect overnight. Your brain’s wiring plays a huge part in resisting changes in lifestyle, and it takes time to establish new habits – up to 12 weeks. Stick with it for at least eight weeks and you should notice a change."
