Hello! I have been using Huel as a semi primary calorie source since April of 2018.
I am a 23 year old male nurse and I do CrossFit 3-4 times a week. I am 5’8" and around 165lbs.
My typical day breaks down like this (I mix ounces and grams, sorry):
Breakfast
Huel 500g
1 serving fruit
3oz chicken
30g avocado
Lunch
Huel 500g
1 servings fruit
6 ounces veggies (brussle sprouts, green beans, corn etc)
Some amount of sauce, like marinara, basil pesto, garlic etc for the veggies
Serving of fish (sardines/tuna/salmon etc)
Dinner
Huel 500g
1 serving fruit
Half serving of mixed berries
32g almonds or almond butter
3oz chicken
90g avocado
6 ounces veggies (Brussel sprouts, green beans, carrots, corn etc)
Some amount of sauce, like marinara, basil pesto, garlic etc for the veggies
Average daily macros (including “fudge” factor)
Calories: 2650-2750 calories
Protein: 165-175g
Carbohydrates: 225-275g
Fiber: 45-55g

PUFA: 35g-40g/day

If I am traveling or with friends I’ll eat other food, like burritos pizza etc. I try not to socially limit myself with regards to food, because that makes life kinda sad and isolating.
In my time with using Huel, vanilla only, I had some on and off issues with gas and GI distress in the beginning. I learned to NEVER to 4 scoops of huel. I have not found any difficulty with my CrossFit workouts and have continued to PR lifts such as a 335lb deadlift,10 back squats at 270lbs etc. My conditioning has continued to improve and I have been able to build muscle and look leaner. I came to Huel looking for an inexpensive food source that I could use to get away from relying on cooking a bunch of chicken and eating rice/oatmeal/bread. Huel has helped me immensely in my meal planning and has not impaired my fitness goals. It is simple and tastes good, and makes me feel good.
I recently got a cholesterol test done.
Total cholesterol: 103
HDL cholesterol: 36
TC/HDL ratio: 2.8 (LOW RISK)
This cholesterol test was not done with fasting, so I am not sure about accuracy, but I find it interesting that I might need to INCREASE my cholesterol more than anything. I am not aware of accuracy issues in cholesterol testing or if there is any credible research about low cholesterol and health problems.
I will be getting a more thorough blood panel that will be done fasted later this week so I will update this post with those results. I would also be happy to answer any questions. Thanks!

The most concerning test to come back was the creatinine level. I had been taking a creatine supplement, so after talking with a physician I decided to put that on hold and retest my kidney function in a few months. Creatinine can be elevated in people who are lean and muscular or engaging in vigorous exercise so I’m not super concerned, but I’ll see what effect stopping the supplement will have.
I also need to go outside more for my Vitamin D level but I’m not really concerned about that.
Overall, I’m extremely pleased with my lab levels and feel that a diet with a Huel base can help to support a healthy and active lifestyle.
