It's very hard to give specific recommendations for anyone on diet as each person is their own story with immense differences of circumstances and constitution.
So for me....I take on occasion one supplement which absolutely for some unknown reason will put on weight. About a half a teaspoon when I take it daily.
Ten dollars or so for a powder bottle which would last many months at that rate of consumption. This takes about a week for efffect of this sort.
This is called D-Ribose Powder. It may be found in vegan form by NOw sports the distributor.
Weight lifters occasionally bodybuilders take this supplement to assist in strenght muscle growth. It is a simple sugar that begins the metabolic process for ATP production. Google it and you may find more about it.
Keep in mind supplements of this sort such as creatine are being used by others with muscle weakness problems now on occasion in the medical field.
These things have application beyond just the strenght sports.
Creatine if one has any kidney water or such problems I would not recommend this as it requires much water to metabolize and if not may cause problems.
But if one hydrates well this may be assisting as well. Most with creatine however just put on ten or so pounds and stays there....much is water weight as it favors retention of water. A tiny bit of creatine perhaps a 1/4 teaspoon may however work well with ribose. They work together a bit. I would absolutely not advocate for what is called creatine loading as this may cause problems as well. Creatine may be found in vegen form as well.
A process called microbiotic fermentation is the means for vegan sources of these things. Kind of like growing yeast and harvesting certain products of the growth and fermentation.
If one can do them one exercise will absolutely stimulate the appetite..squats.
Keep in mind I am male and older and vegan for many years. So single things like this may or may not work for you as they do for me.
20 plus years of being vegan changes things bodily.
Ongoing medical problems and consult your doctor first before any supplements. They will not know what you are talking about so send them a email with a link. If no problems ribvose seems benign to me.
Once weight is up and stabilized you can of course drop it. Take it again if the problem occurs again.
As you may know that is to much weight to soon to loose. It cannot be healthy. In any event you must hydrate very well with great weight loss as the metabolism of fats tend to be more inefficient that carbohydrates(looseing weight you loose muscle but largly fat)....so more waste products are produced.
They must be excreated...water assists that process. Things called ketones and ammonia which can be quite toxic are produced by a predominance of fat metabolism as opposed to carbohydrates. Hence the problem diabetics have from many years perhaps of difficulty metabolizing carbohydrates.
Diabetics untreated lack insulin which metabolizes sugar carbohydrate basically. Which is why the basic test for diabetes is a blood sugar level. Above a certain level consistantly infer diabetes. So over time it may have negative effect, predominace of fat as opposed to carbohydrate.
Ah its been a while
ketoacidosis is the acute presentation of the complication of lack of insulin in a diabetic crisies..as the name implies metabolism of fat in predominance leads to PH changes of a subtle kind which can be negative for function in many manners. WE perhaps are not diabetics...but the same basic principles apply. Bodybuilders per example though in perfect health will when attempting to loose fat to exclusion of muscle, which requires virtually no carbohydrate consumption consume enormous quanities of water...otherwise they would be completely functionally deabilitated.
Protein also requires comparitively much more hydration to metabolize, but again some protein is consumed with dramatic weight loss as muscle metabolism but in the main it is fat that is metabolized.
Testing of bodily PH level may be done(in various forms to my dim recollection some more sophisticated then others) but without overt symptoms is probably a excessive endeavor to my opinion.
Minute may be the fluctation of PH which only presents as tiredness or lassitude. EAch of us has a natural PH which with some variance is a experiment of one as well. So normal range covers a lot of ground. Basically uninterpertable unless one has a solid baseline to compare to.
With dehydration of any significant sort...great muscle strength loss is incurred in the order of more than 10%.
