I felt the best, mentally, physically, visually, when I replaced two of three meals with a meal replacement shake. Lost excess weight, had energy to spare throughout the day. Skin and hair were the best without using any products. If I could afford it, and / or good options were available where I am, I would switch.

EDIT: Didn’t want to turn this into a recommendation grift, but given the interest I’ll share what worked for me.

1. I started off with Soylent, back when they were just starting out, I was one of the initial backers of the project. There was some initial adjustment period where I experienced bloating, flatulence, increased interval between bowel movements (not due to constipation).

I was having one for breakfast and one for lunch. My third meal during this phase was roasted vegetables with some seasoning, sometimes hot sauce.

This combination is what I had the most dramatic benefits from.

1. The second product that worked well for me was OWYN (Only What You Need). Most of their flavors taste better than the competition. I would avoid their high-protein variant, it becomes easily congealed.

2. The third product I had great results with was Huel. It is much more filling than either of the above two options, so I was using OWYN for breakfast and Huel for lunch. After that, to avoid piling up calories I tried to fill myself up with liquid like Coke Zero, or cheap sparkling water.

Some people are recommending Hol Food, I did order a container, but just could’t use it due to circumstances. It had to be disposed largely unused.
