The phrase "a viable weight" is correct and usable in written English.
It can be used in contexts discussing measurements, assessments, or considerations where weight is a factor in determining feasibility or practicality.
Example: "In evaluating the materials for the project, we need to consider a viable weight that ensures both durability and ease of handling."
Alternatives: "a practical weight" or "an acceptable weight".
The results obtained helped identify the minimum level of polymer-to-metal adhesive strength and an optimal PMH-component architecture which are required in order for the direct-adhesion PMH technology to be considered a viable (weight-saving, parts-consolidation, manufacturing process-chain compatible) alternative to the currently used PMH technologies.
An example is provided of a woman who had had a stroke, where information was provided to her husband to optimise 'portion control' [Participant quote, [ 31]: 183] at mealtimes, as exercise was not a viable weight-reduction strategy.
When the two effects occur simultaneously, it is possible that selection for reducing cell area produce a genetic reduction of the "minimum viable weight", opposite to the physiological increase due to the effect of temperature, which allows a higher survival of starved larvae.
The first one is primarily nutrition-sensitive and mediated by insulin/TOR signaling, and is triggered at the minimum viable weight (MVW), which starts a delay timer (whose mechanism is still unknown) that leads to ecdysone secretion [ 14].
The finding that ecdysone signaling is involved in mediating the switch in the developmental response to starvation that occurs at the minimal viable weight [41], [42] suggests the possibility that in Drosophila starvation induces metamorphosis by enhancing ecdysone secretion.
The bail-out response explains why in Drosophila the growth of internal organs becomes independent of nutrition when larvae are starved above the minimum viable weight: because starvation sets in motion the events that lead to pupariation, and those are nutrition-independent.
The question of whether or not the nutrition-sensitive critical weight and the minimum viable weight are identical concepts needs to be investigated in the future.
However, only larvae that reach the "minimum viable weight" [ 49- 520]20] survive to adult, since the major selective factor in this occasion is the increased larval crowding.
Currently, there is a debate about whether the critical weight in Drosophila (the nutrition-sensitive critical weight) is the same as the minimum viable weight, which is defined as the weight that the larva must reach in order to pupariate [ 2, 10, 27].
The researchers said more study is needed before gene therapy becomes a viable treatment for weight loss in humans.
