This is the 1977 logo and dust jacket for a book published by Dr. Rzepela. The name of the author is in ITC Korinna Bold.
Zip Diet was created by Dr. Stanley J. Rzepela, who opened the Zip Diet Center in Boston. The logo started with a font which I cannot remember and have been unable to track down now.

It’s a pity you can’t remember the font that served as the basis for the logo! The p and d with the diagonals remind me of Breadline, but that’s not it.
Assuming that p and d are entirely custom, and Z and t heavily modified, this leaves us with a monolinear bold sans with round i dots and an angled e that was available in 1977. Seeing that all other typefaces are by ITC, I’ve looked into their catalog for potential candidates. Several of ITC’s period sans serifs offered such an e with angled bar as an alternate.
Shown below are ITC Ronda Bold, ITC Avant Garde Gothic Bold, and ITC Grizzly. Ronda is the only one to feature round dots. It also has a Z with pointed corners. The e in closer in Avant Garde Gothic – but it would need to be rotated more, in all these faces.
Does any of this ring a bell for you? Could one of these faces have been the starting point?
