The higher the HCA(hydroxycitric acid) concentration, the more mileage you are going to get out of the supplement. All brands will contain some amount of the extract from the actual fruit, but the amount of the active substance can vary a lot. There are plenty of fly-by-night products around(pretty much all of the ones in local stores) that only offer a very subpar purity.
Often times such supplements(like ones sold at WalMart) only contain 20 or less HCA- even when they are marked as higher(this was the conclusion of a recent study).
The engineering design process is a series of steps that engineers follow to come up with a solution to a problem. Many times the solution involves designing a product (like a machine or computer code) that meets certain criteria and/or accomplishes a certain task. WHAT IS THE DESIGN PROCESS? WHY IS IT HELPFUL? The Design Process is an approach for breaking down a large project into manageable chunks. Architects, engineers, scientists, and other thinkers use the design process to . The engineering design process is a methodical series of steps that engineers use in creating functional products and processes. The process is highly iterative - parts of the process often need to be repeated many times before another can be entered - though the part(s) that get iterated and the number of such cycles in any given project may vary.
