There are many things you can do to help you lose weight. But to think that weight loss in itself is the only consideration would be oversimplifying matters. After all you would hardly want to surgically remove a limb in order to weigh less.
Whilst that might be an extreme way of putting things, many people will employ weight loss methods that are neither healthy, nor truly result in the type of loss that they desire. A person in a technical healthy weight range can still appear unfit if their body fat to lean mass ratio is high.
For these reasons the FlexLoss plan focuses on the truly important type of weight loss i.e. fat loss.
As you gain weight fat is accumulated in various areas of your body in accord with your genetics. You cannot control where it builds up. Unfortunately neither can you decide where the fat will be reduced from when you lose weight again. But that's okay. As long as you are losing fat rather than muscle you will steadily see the transformation affecting your whole body. The important thing is just to encourage the fat loss.
One common misconception is that weight loss is simply about calories in and calories out. Take in fewer calories than you expend and you will lose weight. To some people the formula ends there and all calories are created equal. But this is simply not true. From the point of view of the energy available to your body from any given calorie the theory is correct, but how your body responds to the calories consumed varies considerably depending on many factors.
A primary consideration is the effect of foods upon blood glucose levels (blood sugar) and insulin. Foods containing carbohydrates that are digested quickly release glucose rapidly into the bloodstream. This in turn tends to induce a greater insulin response that may encourage the conversion of the consumed foods into fat. Note the terms "tends" and "may". This is not an exact science. Nevertheless there is sufficient data available to know that choices of food have a significant effect on whether your body is more likely to lose fat or accumulate fat.
The glycemic index or GI has been devised as a measure of the effects of carbohydrates in food on blood sugar levels. It is good to understand glycemic index, and the more recently introduced glycemic load which takes into consideration the amount of the carbohydrate in typical portion sizes and therefore may more accurately reflect the effect on the body.
The FlexLoss plan pays careful attention to these factors. Included carbohydrates are primarily low-GI, and are scheduled throughout the day in such a way as to discourage spikes in blood sugar levels. This approach strongly encourages fat loss and lean body mass retention.
