Not so long ago the idea that food could cause some people a variety of uncomfortable symptoms was considered cranky. Now the theory of food sensitivities is becoming more widely accepted by the medical profession. But the idea that there may be a connection between weight gain and food intolerances is relatively new. Most food intolerance experts now agree that the problem is caused by a damaged gut wall which results in partly digested food molecules passing through into the blood. The gut can become damaged over time, due to continual irritation by poorly digested food matter causing inflammation and toxin accumulation.
Food intolerances can develop at any age and are particularly connected with stress.
This is why you may suddenly find that you cannot tolerate a particular food even though you have never had a problem in the past. Water retention is often a symptom of food intolerances, for example a bloated feeling in the abdomen especially before menstruation, puffy ankles or swollen joints. Excess fluid can be a major factor in weight gain. Sometimes I will see clients who find they spend a great deal of time in the loo during the first weeks of the programme and this is because they are getting rid of excess fluid which they did not know they had and which can help them shed pounds. Saturated fats as found in fried food, cakes, biscuits etc. have many health disadvantages including weight gain and increased likelihood of heart problems.
