Below, find a copy of an article on CLA and what it is/does.
As far as getting enough protein, you might want to consider protein supplementation using protein drinks. MetRx, EAS, AST...there are several great companies out there making protein powders that can be mixed with water or milk to help you get a boost in your daily protein intake. You can purchase them online or at your local GNC. Believe it or not, for a woman of your weight, 75 grams a day is actually a little under the recommended daily amount for an exercising individual, especially if you are lifting weights and working for muscle growth. Most nutritionists these days advise taking 1 gram of protein per pound of body weight, which would mean a daily intake for you of about 100-110 grams daily.
Many protein powders can contain as much as 50 grams of protein per serving. Also, protein bars (Like "Pure Protein", one of the best-tasting on the market, IMHO) can contain from 25 to 30 grams of protein per bar, yet the carbs and fat are low.
So, consider following your doc's advice. Beef up the protein any way you can (i.e. a whole can of tuna contains approximately 32 grams of protein. A cup of cottage cheese contains 26 grams of protein...etc) and take the CLA to spare loss of lean muscle tissue.
Keep us posted and good luck!

Conjugated Linoleic Acid
Also indexed as: CLA
What does it do? Conjugated linoleic acid (CLA) is a slightly altered form of the essential fatty acid linoleic acid. Preliminary animal and test tube research suggests that CLA might reduce the risk of cancers at several sites, including breast, prostate, colorectal, lung, skin, and stomach.1 2 3 4 Whether CLA will have a similar protective effect for people has yet to be demonstrated in human research.
Animal research suggests an effect of CLA supplementation on reducing body fat.5 6 Limited placebo-controlled human research found 5.6–7.2 grams per day of CLA produced nonsignificant gains in muscle size and strength in experienced7 and inexperienced8 weight-training men.
Animal research also suggests an effect of CLA supplementation on limiting food allergy reactions,9 preventing atherosclerosis,10 11 and improving glucose tolerance.12 As with the cancer research, the effects of CLA on these conditions in humans remains unclear.
Where is it found? CLA is found mainly in dairy products and also in beef and poultry, eggs, and corn oil. Bacteria that live in the intestine of humans can produce CLA from linoleic acid, but supplementation of a rich source of linoleic acid did not produce increases in blood levels of CLA in one human study.13 CLA is available as a supplement.
CLA has been used in connection with the following condition (refer to the individual health concern for complete information):
Ranking Health Concerns
Other Athletic performance (body composition and strength)
Who is likely to be deficient? No deficiencies of CLA are reported or believed to occur, since it is not an essential nutrient.
How much is usually taken? Animal research uses very large amounts, equivalent to several grams per day for humans. Until human research is conducted with CLA, the appropriate amount to take of this nutrient remains unclear.
Are there any side effects or interactions? The side effects of CLA are unknown, due to the limited research in humans. However, one unpublished human trial reported isolated cases of gastrointestinal upset.14
At the time of writing, there were no well-known drug interactions with conjugated linoleic acid.
Within Healthnotes Online, information about the effects of a particular supplement or herb on a particular condition has been qualified in terms of the methodology or source of supporting data (for example: clinical, double blind, meta-analysis, or traditional use). For the convenience of the reader, the information in the table listing the supplements for particular conditions is also categorized. The criteria for the categorizations are: “Primary” indicates there are reliable and relatively consistent scientific data showing a health benefit. “Secondary” indicates there are conflicting, insufficient, or only preliminary studies suggesting a health benefit or that the health benefit is minimal. “Other” indicates that an herb is primarily supported by traditional use or that the herb or supplement has little scientific support and/or minimal proven health benefit.
