Considering you don't have an excessive amount of loose skin already, it is possible to shed weight and keep your skin firm in the process. The idea is to keep your body well hydrated day in and day out. NEVER EVER let yourself become dehydrated. Drink plenty of water throughout the day, and NEVER EVER eliminate your carbohydrate intake. Most people who have lost weight too fast by eliminating their carbohydrates ended up with a lot of excess skin afterward. The whole idea is to lose weight to get healthier and, of course, to look better with your clothes ON and with your clothes OFF. Here are some tips
Follow a well-rounded, balanced diet.
Follow a full-body exercise routine alternating with a split routine every four weeks. For example, full-body routine four weeks, split routine four weeks, full-body routine four weeks, and so on.
Considering that you don't have stomach ulcers and are not on blood thinners, you should also take ONE TEASPOON of cold artic cod liver oil ONCE PER DAY with your evening meal.
Take 1000-1500mg of lecithin per day. Lecithin has been known to increase the elasticity of the skin.
Anything you can do to increase circulation will also help. Skin brushing techniques are excellent. Do a search on the internet for skin brushing to get all the info you need. Deep massages are also excellent.
Most importantly, if you are more than 75 pounds overweight, do not shed weight too fast. The more you weigh, the easier it will be to shake off weight on this program, so ease into it slowly, so you shed about 3 pounds per week. Doing this will prevent sagging skin. If you lose weight too fast, you will end up with loose skin 90% of the time.
Some of my clients have done weekly body wraps with great success, but it can get messy. You can do this as an option, but it's not necessary.
As an option, you can also take a supplement called collagen.
As I stated above, one key to increasing your skin elasticity is to keep your body well hydrated. Yes, drinking water will do this. The average person needs at least ½ an ounce of water per pound of body weight. Possibly more, depending on
the type of exercise you do daily. The reason why so many people end up with loose skin after shedding weight is that they go on low carbohydrate diets that will, in turn, dehydrate the body. If you drop weight and are dehydrated in the process, you will see the scale weight go down, but unfortunately, most of the weight being lost is nothing more than water weight. If you are losing 2-3 pounds per week, you are doing great. If you are losing 4-6 pounds, you are pushing the limit. Any more than 6 pounds per week, and you are sure to end up with loose skin after losing weight because chances are you are restricting too many carbohydrates from your diet. Cutting out refined flours/bread and sugars will yield the best results.
Also, avoid getting on the scale every week and go more by how your clothes are fitting. I always tell my clients to try on the tightest pair of pants they have and then follow my program for four weeks and try them again. After four weeks, those tight-fitting pants will be a thing of the past.
Follow all the above, and you will see satisfactory results.
