Each bar has 180 calories or less. According to the web site:
Simply eat FullBar with an 8-ounce glass of water 30 min. before your 2 biggest meals of the day. The upper part of your stomach is stretched out and tells your brain: "Stop! I'm full!" That's because FullBar uses the same principles as weight-loss surgery. By meal time, you'll eat less and your hunger will be completely satisfied.
The plan is for 12 bars a week -- participants eat two bars a day 5 days a week. On weekends they have the choice of 1 bar each day, or two bars one day.
I'm not a dietitian or nutritionist, so I can't evaluate the ingredients or the nutritional value of the bars. However, the first ingredients are brown rice syrup and "puffed rice cereal." Comparing that to the Kashi bars I like, the first ingredient is a blend of whole grains.
It doesn't take a PhD to figure out how this plan works. The puffed rice cereal absorbs the water, expands and you feel full.
It takes about 30 min for your brain to realize you have eaten, so if you eat anything and drink water 30 minutes before a meal, you will feel less hungry and are less likely to overeat. Remember the apple diet from a couple of years ago? Participants ate an apple 30 min. before each meal. That worked, too. (Shoot, I've eaten a couple of saltines before a meal and been less hungry.)
Comparing prices -- On sale right now, a three-month supply of FullBar is $175 or about $1.22 for each bar. The regular price is $2.50 per bar. A box of six Kashi bars range from $3.67 to $5.00 per box -- 61 cents to 83 cents each. Even at the highest price I've paid, that is at least $55 less than this special diet bar.
I am skeptical of any fad diet. They just do not work for long-term healthy weight loss. But when I see something like this I just hope people anxious to lose weight don't get sucked in.
If you are interested in trying this type of eating plan, buy some high-quality granola bars (such as Kashi brands) from Walmart and save some money.
