I'll just point out the Stalingrad diet, as recommended by Kurt Zeitzler.

"Want to get below a healthy weight? Want to look like a stick insect thats being doing meth for years? Then try the stalingrad diet. 40gs of bread in the morning and at lunch followed by a bit of horse meat at dinner"

Zeitzler was urged by his military colleagues to give the breakout order himself, but refused to act on his own, deferring to Hitler's authority as Commander-in-Chief. On hearing that Göring had told Hitler that the supply situation in Stalingrad was "not so bad", Zeitzler wrote in his diary: "Apart from the fact that it would do his (Göring's) figure a power of good to spend a little time in the Kessel, I can only assume that my reports either are not read or are given no credence." Zeitzler, in a gesture of solidarity with the starved troops in Stalingrad, reduced his own rations to their level. Having lost 26 pounds in two weeks, Hitler (after being told by Martin Bormann of the diet) ordered Zeitzler to stop the diet and return to normal rations.
