I have been hearing also about a ketogenic diet using exogenous ketones. I’m 63 years old, 5’4″ and weigh 170. I joined LA fitness two weeks ago and I’m working with a trainer. My goals are weight loss and strength training. I’ve been doing (and I’m committed to) about 45 minutes of cardio 3-5 times per week and weight training 3 days a week. I am in fairly good health with well controlled mild hypertension as my only health concern. Any information you could provide or direct me to would be appreciated.

I had to do a little research on this one, Susan, but I am glad to be kept on my toes! For our other readers: exogenous ketones are those ingested as supplements as opposed to those produced by the body (called endogenous). The intended goal of dietary-induced ketosis is for the body to use ketones, or fat-derived compounds, as an alternative fuel source instead of carbohydrates for certain body systems.
An outside source of ketones, such as beta-hydroxybutyrate (BHB), in the absence of glycogen depletion, will only produce a short-term state of ketosis lasting a few hours. So you’d need to keep taking the product to get an effect prolonged enough to be significant. You could end up spending well over $100/month – ideal for the supplement company!
Money Down The Drain
During forced ketosis, the body regulates ketone production by shutting down the liver’s production of endogenous ketones and getting rid of excess ketones through urinating.
The use of such ketones (and therefore the bulk of research) has been for its effects on Alzheimer’s, cancer, epilepsy and elite athletic performance. Little is known to establish exogenous ketone use for weight loss. In fact, on PubMed.gov, I could not find one study that directly observed exogenous ketone administration and reduction in body weight. Lots of bits of information that might lead one to assume this would be the case, but no evidence to support such a theory.
My advice – You’d likely be better served by consuming natural caffeine sources to help prolong your cardio workouts for increased fat burning. Coffee won’t break the bank, either!

Two questions for you, actually! Hope you don’t mind!
1.) I’m struggling to think of easy, healthy options to take with me to work to eat for lunch. I’m not much of a meat eater, but I do like chicken. Any suggestions?
2.) I’m also struggling with the fact that it’s winter, and all my cravings seem to be the warm, unhealthy “comfort foods”. I’m lately craving mac and cheese, heavy soups, and things of that nature. Any suggestions for something that’s “warm and cuddly” without all the fat and calories? Thank you so much!
– Megan K.
For easy, healthy lunch options my suggestion would be to assemble wraps and hearty salads/soups, or to use leftovers. Roll up some hummus, cucumber, tomato and feta in a spinach or sun-dried tomato tortilla. You can add a handful of beans and chicken breast strips to a pre-made salad in a bag. Since it takes a full can of soup (2 cups) to make a decent meal, pair the soup with raw produce so you don’t add sodium. Leftovers are quickest, of course – just place in the containers you’ll take to work when storing them.
Enjoy the comfort foods as a smaller side dishes instead of as a main entrée, or find ways to lighten the recipes. For instance, using low-fat cheese plus adding ham and peas in your mac & cheese, or having a scoop of the real thing accompanied by a grilled chicken breast and steamed broccoli. A bisque soup or chowder pairs with whole grain bread sticks and celery stalks. My all-time favorite warm treat is made by spreading almond butter on freshly made rye toast, topping with apple slices and a sprinkle of cinnamon, and placing back under the broiler. Using fresh ingredients from room temperature (except meats/dairy) enhances the flavors and makes heating quick.

Is it OK to eat/drink an apple/coffee 1 hour before working out?
– Pavan
Yes, an apple and cup of coffee are okay to eat/drink an hour before working out.
If your workout is intense and prolonged, you may want to supplement a little protein with the apple or a light workout drink during exercise. Alternatively, if you’ve eaten a LARGE meal within 3 hours prior to your workout, you can skip your described snack.

For people who are barely starting to exercise, what would you recommend on a planned diet? I am over 180 pounds and I see and read diet plans. But as a person who is starting to exercise I was curious if there are any recommendations for diet plans. I know this will all depend on maybe a personal assessment but I just wanted to ask.
– Esme
Welcome to the LA Fitness family, Esme! It’s great that you began exercising and want to add in a planned diet. It’s okay to focus on your new exercise routine for a while and once you’ve got that established, then address your nutrition.
What I’d specifically recommend really all depends on what your diet is like now. You should start with assessing your current diet to see where you can improve. Keep a food diary for a few days and enter it into a dietary analysis program, app or website that will show the average calories, fat breakdown, protein, carbohydrate breakdown, and vitamins/minerals you consume.
If there are areas you know need to change, and you can practically address those, start there. You’ll have greater long-term success by amending how you eat rather than adopting a rigid, generic plan that doesn’t take into account your preferences and lifestyle. See our previous article “The 3 Pronged Attack for Weight Loss – DIET.”
That said, you may want to look at some key targets of a healthful nutrition plan:

What is a good alternative to grains as a way to complement the protein in legumes? Legumes are nutrient dense in many ways, including protein. But legume protein is low in methionine, an amino acid that our bodies cannot make. For this reason legumes have traditionally been combined with grains, which are high in methionine. Grains are low in another amino acid our bodies cannot make, lysine. Legumes are high in lysine. For this reason, legume and grain proteins are said to be complimentary. But if I am considering a long term dietary shift away from grains, I cannot be reassured by that. We still need to combine our proteins well over the course of several days. Unfortunately, grains are not a nutrient dense food. They are very high in starch and low in phytonutrients. So, what are some nutrient dense sources of methionine and cysteine? Or, in simpler terms, what is a good alternative to grains as a way to compliment legume protein?
– Benjamin H.
Vegan diets do tend to be low in methionine1, one of the essential amino acids. Interestingly enough, it’s actually proposed that a lower methionine intake is better for longevity1.
The World Health Organization recommends the adult dietary requirement is 10.4 mg of methionine per kg body weight per day to cover obligatory oxidative loses2. Whereas the US Recommended Dietary Allowances combine the methionine requirement with cysteine (a non-essential amino acid) for a total of 19 mg combined of methionine and cysteine/kg/day3. In plant foods, there are about equal amounts of methionine and cysteine.
“Wheat and rice proteins are comparatively low in lysine but better sources of methionine whereas beans and peas are relatively high in lysine yet in lower methionine.” — www.vegsoc.org/protein
