I can't tell you how many people ask if they will lose weight while they are cleansing. Tons of them... The answer is yes, but it's not quite as simple as that.
You definitely do lose weight, but not all the weight you lose is fat and some of it will come back if you’re not careful after the cleanse finishes.
A lot of the weight you will lose is excess fluid. Excess fluid (fluid retention or edema) has many causes including; too much salt or not enough protein in the diet, food and environmental allergies, poor circulation, and hormonal imbalances (women are particularly prone to fluid retention prior to and during their periods). Fluid retention masquerades as fat (and looks like fat) and can add up to 2kgs to even the smallest frame.
Juice cleansing can help to flush this excess fluid due the natural diuretic properties of many of the ingredients used and the cleanse’s high content of water (which actually helps get rid of excess water, contrary to what you might think).
In addition to this, because the cleanse is relatively low in kilojoules (approx 4400 kilojoules per day for a Level 1 cleanse), you will most likely lose some fat also.
It’s pretty simple, if you want the weight to stay off following the cleanse, you need to eat less salt (the main offender for fluid retention) and follow a healthy, wholefoods diet (see our blog post on Simple Healthy Eating Principles). If you can stay off the booze, takeout and sugar for a few weeks after your cleanse, you’ll do your body (and weight), the world of good.
