I am currently in a fat loss phase and I am worried about losing the muscle I worked so hard for over the winter. I am on a vegan diet and my calories are fairly low right now as I try to get ready for a vacation in Brighton.

I am making sure to keep my protein as high as possible but I am wondering if there are any specific supplements I should be taking. I have heard that B6 and B12 are important but what about things like creatine or leucine?

Has anyone here successfully done a very lean vegan cut? I would love to hear how you structured your training and what your main protein sources were during the final weeks. I really want to keep my strength up as much as I can.

Totally understand the worry, LeanLass92! The key on a low-calorie vegan diet is to really prioritize protein intake and continue with heavy resistance training. Do not drop your weights too much, focus on maintaining strength. πŸ’ͺ

VeganStrong, that is spot on! Maintaining intensity in your workouts is paramount. Your body needs a reason to keep that muscle. If you just do light cardio, your body will happily burn muscle for energy alongside fat. Keep lifting heavy! πŸ”₯

Echoing VeganStrong and Push50, progressive overload is non-negotiable. Even in a deficit, try to either maintain your reps/weight or even push for a small increase if possible. This sends a strong signal to your body to preserve muscle. πŸ’―

Absolutely, protein is crucial. Aim for at least 1.6-2.2g per kg of body weight. Focus on complete protein sources like tofu, tempeh, seitan, lentils, and a good quality vegan protein powder. Do not forget quinoa and nutritional yeast for extra amino acids! πŸ₯¦

@AnimalLifter, thanks for the protein source suggestions! Do you have any specific vegan protein powder brands you recommend that are not too chalky and taste decent? I struggle with finding a good one. πŸ€”

@GreenGains, I personally like Myprotein Vegan Blend (chocolate smooth is good) or Garden of Life Sport Organic Plant-Based Protein. Both mix fairly well and have decent flavor profiles. Give them a try! 🍫

@AnimalLifter, awesome! Thank you for the recommendations. I will check those out. Are the chocolate flavors usually safe bets for taste? I have had some truly awful protein powders. πŸ˜‚

Has anyone had success with nutrient timing on a vegan cut? I try to get most of my protein in around my workouts, but I am not sure if it makes a huge difference compared to just hitting daily macros.

@PlantPowerlifter, I personally find nutrient timing helpful for satiety and energy levels, especially pre and post-workout. Getting some quick-digesting protein and carbs in after a session can really help with recovery and curbing hunger later. πŸ‘

Do not underestimate the importance of sleep and recovery! When you are in a deficit, your body is under more stress. Aim for 7-9 hours of quality sleep to optimize muscle repair and hormone balance. This is often overlooked. 😴

I have been using a lot of high-fiber, high-volume foods to feel full on fewer calories. Think huge salads, roasted veggies, and oats. It helps immensely with hunger pangs on a cut! Anyone else do this? πŸ₯¬

What sort of calorie deficit are you running, LeanLass92? Sometimes people go too aggressive, which makes muscle loss much more likely. A moderate deficit (300-500 calories below maintenance) is usually best for muscle preservation. ⚠️

@CalorieCoach, that is a huge point. I made the mistake of cutting too hard once and felt absolutely terrible, lost strength, and definitely lost muscle. Slow and steady wins the race. 🐒

Tracking your macros meticulously is super important, especially protein. Use an app like MyFitnessPal or Cronometer. It is easy to overestimate protein intake on a vegan diet if you are not careful. Knowledge is power! πŸ“ˆ

Consider incorporating occasional refeed days, where you strategically increase your carbohydrate intake for a day or two. This can help replenish glycogen stores, boost metabolism, and provide a mental break without derailing progress. πŸš€

@MuscleMeccaCrew, completely agree on refeed days. Not only for the physical benefits but the psychological ones too. It is so much easier to stick to a deficit when you know a higher carb day is coming up. Keeps me sane! πŸ™

Do not forget about amino acid supplementation. BCAAs or EAAs can be beneficial, especially if your protein intake is on the lower end of the recommended range or if you train fasted. They help with muscle protein synthesis. πŸ’ͺ

What about cardio? Should LeanLass92 be doing more high-intensity interval training (HIIT) to burn fat faster, or stick to steady-state cardio to preserve muscle? Always get confused on this part during a cut.

@CardioKing, for muscle preservation on a cut, generally, lower intensity steady-state cardio (LISS) is preferred. HIIT can be very taxing and increase cortisol, potentially leading to muscle breakdown, especially when calories are low. Stick to LISS! πŸƒβ€β™€οΈ

@PumpChaser makes a great point. I do 30-45 minutes of brisk walking or light cycling for LISS, usually in the morning before my first meal. It helps with fat burning without impacting my strength training recovery. Plus, it is great for mental clarity! πŸšΆβ€β™‚οΈ

Ultimately, listen to your body. If you are feeling excessively fatigued, weak, or constantly hungry, your deficit might be too aggressive or your recovery is insufficient. Adjust as needed; this is a marathon, not a sprint. πŸ’–
