Isis the slim fast diet safe while breastfeeding?

Isis the slim fast diet safe while breastfeeding?

Diet not safe: Its not a good idea to diet while breastfeeding. The baby on its own will be taking in anywhere from an additional 500-1000 calories a day.

Just how fast does slim fast work? Would slim fast have to be drunk everyday to start seeing results?

Doctor recommended?: Did a physician actually recommend slim fast for you? Starvation diets do not work. In fact they often lead to rebound weight gain more than was initially lost. There is no proof that slim fast will lead you to any real or lasting weight loss. Perhaps you should discuss your diet plans with your physician. ...Read more

Yes, but..: Slim fast has horrible ingredients, and I would not feed it to my dog if I had one..From their website, they list Hydrogenated soybean oil, High Fructose Corn syrup, etc. Soybean oil will make you fat, and so will high fructose corn syrup.

What can drinking foul smelling milk do to you? I drink slim fast everyday in the same bottle I don't always fully wash not sure its that or the milk

What can drinking foul smelling milk do to you? I drink slim fast everyday in the same bottle I don't always fully wash not sure its that or the milk

Usually nausea: I see you have the component of OCD involved so you are likely to worry more than others. Foul smelling milk is usually spoiled, if it hasn't caused you stomach upset, that's fortunate. It would unlikely result in any serious harm. Smell the milk separately to figure out the source. When in doubt, you can replace the bottle you mix it in. Otherwise wash with good soap/water and smell the bottle. ...Read more

Is it safe for me to have slim fast shake with a throyd goiter?

Is it safe for me to have slim fast shake with a throyd goiter?

Not safe for anyone: I don't think Slim Fast is particularly safe for anyone because it has Splenda and Acesulfane Potassium, chemicals that I consider toxic (though not all Drs. agree) as well as ingredients from GMO corn, soy and canola oil, all best avoided.

Is it safe to take orlistat (xenical) while on slim fast meal replacments?

Is it safe to take orlistat (xenical) while on slim fast meal replacments?

Actually good: Since fatty meals will make the side effects of orlistat worse (abd pain/cramp, fatty stool, flatulence, nausea/vomittinf), slim fast is quite slim and thus will be better than a double mac with cheese! xenical really works by teaching how to eat--less fatty/greasy foods. If trouble, consult doc. Good luck. ...Read more

I have a colonoscopy Thursday. I can't eat all day tomorrow. Can I drink slim fast for some calories?

Yes: The purpose of limiting diet prior to colonoscopy is to have a relatively clean bowel when the scope is passed for visualization of the bowel lining. Solid foods should be eliminated but liquids should be used to prevent dehydration. On the preceding day oral GOLYTLY is taken and in many instances a Fleets enema is also used.

Can u drink slim fast while pregnant? Not wanting it for dieting i'm just hungry and it's what I have on hand at work until i get lunch. I'm 21weeks

Protein shakes: You can drink protein shakes for a snack -- but you can also be wise about the protein shake you select. Slim fast has 18 grams of sugar and only 10 grams protein/serving. There are other prepared shakes with much less sugar + more protein that would be satisfying, and keep your blood sugar more stable. One is pure protein by GNC -- 1 gram sugar and 35 grams protein. Other good ones too. ...Read more

In : In order to lose weight, your caloric intake must be less than your energy expenditure. To calculate your energy expenditure and your basal metabolic energy needs, you can go to: http://www.Health-calc.Com/diet/energy-expenditure-advanced. Using this, you should carefully track your food intake, counting the calories on the food and drink you take in daily. You can either decrease your calorie intake, or increase your energy expenditure by increasing your activity. Clearly exercise has a major impact on how much energy you expend. A nutritionist can assist you with your diet and provide some tools to count your calories. ...Read more
