This is a layman marketerís observations on diets and weight loss based upon selling and working first hand with weight loss products for over 10 years.
We avoid weight loss drugs, we do not recommend them as they can be dangerous, however I suppose in some extreme cases with certain obese people benefits may outweigh negative side effects.
Here is where we believe majority of people go wrong when trying to lose weight.
First most people consume way too many carbohydrates and they don't take in enough protein on whatever diet they are on so in effect they are causing their bodies to instead of burning fat to burn lean muscle.
In effect lean muscle burns at rest about 17 times more calories per day at rest than same amount of fat. The amount of muscle you have greatly determines your metabolism and how many calories your body burns each day. This is why people when they come off their diet and start eating regularly again they can put weight right back on as their body is now naturally burning less calories than before. In effect they have slowed down their metabolism. This is especially true it seems of women who have less natural muscle mass than men.
This explains why Atkins diet is so effective. It cuts out a lot of carbohydrates, which because people often eat too many of them cause weight gain. And by eating more protein it is making sure that you don't lose any muscle and may even gain some additional muscle mass.
The second major factor why people donít lose weight is lack of exercise and to a lesser degree wrong types of exercise. For example a brisk walk can cause your body to go into fat burning state called ketosis better than running will.
We earlier discussed how important muscle mass was in maintaining a healthy weight. This is why light resistance exercises (weight training) is so effective in losing weight because it help you add muscle mass. This doesnít have to be massive amounts of weight, any light resistance amount of weight can be effective at adding muscle.
