I understand that these numerous occasions, as enjoyable as they are, are risks for you to succumb to temptation.
There are two major findings, first, you have made a lapse that made you regain the weight and the second you feel guilty and this lapse created an urge to eat certain foods that may have been forgotten while you were dieting.
If you are following the diet, the impact will be a little more important and you must be careful not to lapse during the week.
Regarding alcohol you can consume an alcoholic drink during your celebration meal.
If you can, try to anticipate eating a hearty meal in order to be less hungry at mealtimes. Some good suggestions include flavourful cheeses which can be satiating / filling.
You can offer your friends to bring an appetizer salad by providing surimi or peeled shrimp dressed in Dukan mayonnaise.
In addition to anticipating the excess you will have to think about the response by practicing cardiovascular activity like jogging the next day. Jogging 40 minutes is ideal to compensate for excess.
Above all, do not feel guilty, it is useless, it increases stress and this is not good for the diet.
There is no obligation whatsoever to eat red meat. Eat what you most fancy from the list of 72 protein sources that are allowed in unlimited amounts, including fish, eggs, fat-free dairy, shell fish, poultry and lean, trimmed ham. The important thing is to vary your meals as much as possible.
- Constipation: an exclusively protein-based diet in the attack phase may contribute slightly to a bout of constipation. This is linked to a reduced intake of fibre and fats which play an active role in lubricating stool and ensuring your bowels move properly. Constipation can be avoided by drinking 2 L of water per day and doing a few abdominal crunches when you wake up in the morning. Your daily dose of oat bran also helps: add a tablespoon of bran or a tablespoon of liquid paraffin to salad dressings.
- Bad breath: this is a common side effect of any high-protein diet. Burning off fatty acid reserves releases ketone bodies, which are eliminated through saliva in particular. Chew some sugar-free gum and drink water at regular intervals throughout the day. This unpleasant effect will gradually disappear.
- Headaches: Again, this temporary side effect is common with any high-protein diet in which ketone bodies must be eliminated by the body. Drinking enough water (2L per day) and eating until you are full will gradually reduce these symptoms until they disappear altogether.
