My mom and all her friends talk day and night about this diet! Apparently you aren't supposed to put on the weight you lost, because the diet changes your metabolism...but I feel like that's unlikely, just because ALL diets say you keep off the weight... |

The only diet you need to follow is one where you cut carbs and get a high proportion of your energy intake from meat/fat and non starchy vegetables. Carbs make you fat. Pretty much end of story. |

Exercise certainly is good for your health. Unfortunately, there is very little evidence that it will help you lose weight! |

It's a fad diet, like all other fad diets: worthless. Jay Leno hit the nail on the head when he said, "Americans will do anything to lose weight...except diet and exercise!" Fad diets aren't dieting, they're just fads. Dieting is managing your food intake correctly and sensibly. Consult a medical professional, not some fad food guru, before you begin a sensible diet and exercise regimen. |

This doesn't work for everyone. There is more to it than that. Eat less of what? What kind of exercise? |

Eat healthy and nutritious food where calories actually have some benefit to them. Avoid too many fast burning sugars etc etc.
Do whatever exercise you feel comfortable with, running, cycling swimming.
If you eat less calories than you burn your body will eventually start to use its stored fatty deposits and you will lose weight.
Going on diets for a month and losing 20 pound is all well and good but if you go back to your old diet and old routine you will put that weight back on quicker than you lost it.
Trust me, I was a fat teenager and now I'm neither fat nor a teenager. |

If you have to buy something (outside of paying to garner information you might not get openly) there's reason to avoid it. I'm not dismissing totally as I actually have an acquaintance that lost significant weight with it, however, he was motivated on many levels to perform better as a cyclist AND avoid DMII. When we reviewed the actual kcal intake he was getting, it was pretty low and partially explained the weight loss. He also ramped his weekly mileage up to about 300 miles/week from about 100 providing about a 4000-6000 kcal additional expenditure.
There is evidence that portioned meals and meal substitutes can help people avoid pitfalls of overeating or making poor choices. If someone wishes to pay for that, it's their money.
As far as this product changing someone's metabolism, I don't see that claim on their site but I would not believe it until I saw evidence that an actual met-cart test was performed on a significant no. of subjects. |

The above link gives a fairly good overview of this idea that exercise does not result in weight loss. It is sometimes theorized that exercise prompts us to eat more kcal than we expend. I agree. Hell, I've thought of massive pork chops on 100 mile bike rides. This happens more frequently when I�m not eating and drinking during the ride.
Exercise can work on the cells much like insulin, by sensitizing them for glucose uptake. No uptake = cells screaming in hunger. This is partially why some people with DM eat like crazy yet are hungry. The glucose spills out in the urine leaving the cells hungry. Exercise can help avoid this.
Where I don't totally agree is that exercise is not part of the equation. If you KNOW, document and act according to your goals, exercise does help. Exercising as a free pass to double-latte and sconesville, well, you�re bound to fail. So, eating and drinking while exercising helps us stay on track.
I do like that they pushed more, simple lifestyle changes like walking, using the stairs etc. and that spurt of intense activity followed by inactivity may be troublesome. When I workout heavy on the weekends I feel like I'm gonna starve until Wednesday, often eating a hell of a lot along the way.

I feel like people confuse weight loss with fat loss. One does not imply the other. The key is body recomposition not weight loss.
All diets follow the rule of thermodynamics. You consume less then you burn, hence your body is required to make up the difference. A lot of mainstream diets simply remove the calorie counting portion but by the nature of the diet and what you can/cannot eat create caloric deficit even without conscious calorie counting.
Most trend diets also tend to include hydration weight in their weight loss. I can easily get someone to shift 10-15lbs of liquid in a few days. But that does not change body composition.
Exercise creates maybe 10-30% of total daily caloric expenditure depending on level of exertion/time. Most people spend far less time in intense activity then they believe. Excluding warm up, cool down, breaks, and low intensity, a 90 minute workout normally becomes something like 30 minutes of actual hard activity.
What certain exercise can do is minimize lean tissue loss and increase the % of fat burned for fuel.
But as I've learned from years of experimentation, training, and learning is that if you want to get a lean toned body it takes a lot of sacrifice and consistency in training/eating. It's no longer a "diet" it's a new lifestyle. |

I'm neither an expert on nutrition, biology, or fitness...
But the beginning and the end of the argument in managing calories is knowing and adhering to how your body uses them. If your body is not using enough calories, and therefore turning calories to fat, then you need to either:
1) Consume fewer calories. This becomes problematic, however, when we consider that the vitamins and minerals we need to take in come with calories. Also, it is healthy from an evolutionary standpoint to put on fat.
2) Utilize greater calories. This means building muscles so your body is burning calories during your ordinary routine. Cardio will only burn higher amounts of calories for a short period of time each day. Putting on muscle will burn more calories in maintaining that muscle. Also, cellular respiration during weight training, in my experience, burns much more calories than cardio.
Eat better. Exercise. Build lean muscle. Maintain this life style.
...... And ignore the mercenary scientists that push new diets/clubs/equipments. You won't get a more expert opinion than common sense. |

I'm not convinced that there should be much reason to be concerned about vit/mineral deficit if one reduces kcal intake while increase the nutritional quality at the same time. This is epecially true of fat soluable vits ADEK. D being the outlier as research is indicating potential global, chronic low levels.
I agree about ignoring much of what is pushed for clubs and diets but disagree about expert opinions. It's up to the consumer to best understand the source of the information, what the information source potentially gains through their message, and to come armed with some basic knowledge.
Common sense does not tell us why animal sources are better sources of iron (Heme vs. non-heme) or what happenes to Vit-C when we heat it. This leaves the consumer with common sense ideas like "fat must be what makes me fat". Consumers are not dumb, it's just that we can't be an expert in every topic.
One of my only major issues with Micheal Pollan of "The omnivours Dilima" is that he faults the scientists for breaking down nutrition and looking at the micro-picture. I think we need those people and more to develop a macro-picture. Let's put blame where it belongs, with the marketers of questionable food products (Maybe Medifast. Woo-Hoo back on topic!) and, unfortunatly, with uneducated consumers.
At least the OP is asking questions and that puts them ahead of many. Who knows, maybe preportioned foods are the answer. |
