Exogenous Ketones
I have been reading more about exogenous ketones and their potential role during a fat-loss phase, particularly around energy availability, training performance, and appetite management. For those who have used them successfully, when do you find they provide the most benefit? Pre-workout, during fasting periods, between meals, or at another strategic time? I am especially interested in whether you have found them more useful for performance, adherence, or actually improving body composition outcomes.

I use KE4, but it wont cause weightloss, no more than taking in carbs or protein will. The ketone esters just provide nutritional energy in an ketone efficient manner. Now, the best way to use the KE4 is for when doing long duration cardio, if I run 10miles fasted and pull myself into ketosis based on verification with a glucose-ketone monitor, then I can use KE4 to keep myself in that system while replenishing energy. Example: if I run 10miles, blow through my glycogen, now my bloodglucose drops, I need energy say to run/walk 5 more miles, I'll blast a KE4 rather than taking glucose. Then before bed if this was done in the afternoon, blast more KE4, go to bed. Get a solid 20hrs of ketosis for weightloss before eating again. This is a great AMPK pathway use with it, it in my opinion is not good for mTOR or micronutrients or macronutrients.

@Mike Schultz no feeling, but the ketones are measurable with a ketomojo. Its just a matter of how you use the energy, it has a place in targeting ketosis or reducing inflammation post event.
IGF1 LR3
Is is possible that 40mcg IFG1 Lr3 preworkout the afternoon before can cause me to feel little hypoglycemic the next morning, mid morning? It's happened couple times now and it's the one variable that I possibly narrowed down. I was thinking it had something to do with trace minerals or berberine originally but took those out. I also used PEG MGF after workout but that may not matter. Anyway, it went away after eating bannana and pretein bar all three times. I don't really know what hypoglycemic feels like but this is what I am guessing it feels like. I did eat my normal shake meal early in the morning, which is full of all sorts of stuff like avacado, pom, protein powder, fruit.

I dont use IGF-1LR3, but from my understanding using it can cause hypoglycemia easily with a very controlled diet. The best thing I can offer here is to track it, a continuous blood glucose monitor, a normal glucose monitor, Ketomojo, or a lumen for a less precise but a general trend to monitor where you are. This way you can figure out when and where to add carbs for optimal use of the igf-1 addition.
Elderly man
Hello Hello, any tips to help and old 70 years old man increase his appetite. He lost a lot of weight and muscles du to diarhea , being pre diabetic and not having appetite. Now he suffer from constipation or incomplete elimination and lack of appetite which affect his total energy

Is this for you? It sounds like a FODMAP issue, something you are eating is causing problems. I would look at an elimination diet or maybe see a dietician to sort that out. As for increasing appetite while managing glucose, this could be a recipe for GHRP-6 and a low dose GLP-1, but before going polypharmacy, I would look at what is causing the diarrhea in the diet.
GLP1 Stalling and Best non GLP1 fat loss protocol
Hello all you brilliant people. So Im wondering if any of you out there have experienced what I would call a stall in progress with GLP1 use. I’ve recently listened to @Anthony Castore on DDT and also The Ultimate Asset about this issue and I would like to dive more into figuring this out. Case Study my wife age 49. Fairly healthy eats healthy fairly sedentary but gets around a lot on our small hobby farm. She started Tirzepitide about a year ago and initially had great results. Her practitioner titrated her up over time up to the max dose of 15mg. The last 3 months she’s stalled and actually put weight back on. Note: my experience with GLP1 was way different, but I did not follow the medical advice and micro dosed it with other foundational modalities. Anyway I’ve had conversations with her about the foundational things Anthony has iterated. But what do I know right? Well now she is starting to believe me. She’s changed some of her habits but still no results. My question is: Is there a way to reset? Say go off the GLP1 rebuild cellular integrity redox balance then reintroduce it at a way smaller dose? Is there any good non GLP1 fat loss protocol that could be utilized instead? I came up with just a foundational protocol and called it her 10 commandments. I will share it here. If anyone would like to look it over and add their opinion, supplements, peptides, modalities, or critiques it would be greatly appreciated! This is what I’ve came up with so far. Jill’s 10 Commandments 1. Morning Sunlight 5 to 15 minutes even when it’s cloudy. Evening Sunset 5 to 15 minutes. Grounded and Barefoot. (Circadian) 2. Breakfast after 9AM 3. Last meal by 7PM 4. Limit Carbs (no more than 100 grams per day) Eat Protein and Fat. Eat any carbs early in the day.  5. Daily Activity (15-30m) morning walking  6. Resistance Training 2x Week (15-30m)  7. Light environment. No blue screens 1hr b4 bed (including phone) Blue blocking glasses in the office setting. 8. Daily Hydration with electrolytes 64oz minimum.  9. Rest day Saturday, morning cold plunge, evening sauna. 10. 8hrs Sleep (eliminate all light sources)

Not a doctor, but trying to break through a plateau with a GLP-1 dose escalations is generally not advisable, in my opinion. I assume the escalation is to lower food noise, but is that all that the drugs does? No. GLP-1s provide a great opportunity to shift lifestyle and food associations in addition to blood markers. Example if the food noise is based on association, is there always snacking when they get home from work, snacking after dinner, or snacking while doing (insert association). I personally believe that using GLP-1s to target food noise with constant escalation creates a negative feedback loop with the ghrelin receptor processes. If you constantly remove the hunger sensation, you negatively affecting all of the downstream value that ghrelin does offer with GHRH, GH, IGF-1, etc. Then with reduced GH you will have more muscle loss, more bone mineral density loss, ect. So in the balance here, I wouldnt just keep escalating, I would target the other part of the equation with weightloss and quality of life. Less focus on calorie in and more focus on calorie out. This is where I would look to better harness other aminos like Leucine and L-Carnitine (1g dose with fasted cardio along side 5-10g acetylated L-Carnitine or 10g of Leucine with 50g of carbs with hypertrophy training). Add in proper vitamins and minerals (vit D, zinc, C, B12), eat foods that are higher nutriental value with less desire. When it comes to snacks, I use my PF11 method (something I made up), any snacks I buy and stock the pantry with are total calories divided by adding protein and fiber together, if the ratio is over 11, I dont buy it. Further introduce peptides that can offset some of the issues of dose escalated GLP-1s like CJC, ipa, etc. Lastly, if the person has a tanked T3 or is feeling cold all of the time, has severe unattachment, etc. It might me time to back off the higher doses GLPs to get back to feeling happy and human, even if their body image is short of their personal goal. They can return to normal and then start the weightloss journey again, nothing goes up or down in a straight line in a heslthy fashion, not stocks, not planes, and not weight.
