I’ve been consuming Huel for 75-100% of my meals for over 3 years now. During certain phases I’ve put on weight by eating in a caloric surplus largely derived from adding Light in colour Olive oil to my Huel shakes. It is fairly tasteless, and very calorie dense so you can easily consume 1,000 calories in one shake without any discomfort while consuming and without any trouble shaking the shaker Huel is sold with. It is also relatively cheap (£0.25 per 100 calories or so).
However, for athletic performance purposes I’d ideally like to gain weight by increasing calories and keeping fat at a minimum (with protein determined based on an amount per kg of bodyweight). I’ve tried using powdered oats before, but could only fit 50g into the Huel shaker alongside 133g of Huel and the water without it becoming too thick.
Has anyone any recommendations for a carb source that would mix well, is easily consumed in large quantities throughout the day, and isn’t super expensive? Has anyone tried Fructos, Dextrose, Maltodextrin, Highly Branched Cyclic Dextrin etc? Are the health concerns with any of these sources? Thanks
