The hunger issue is 50/50. About half of V-Dieters report being hungry at times. Pretty natural: it’s a lower carb, lower calorie diet after all. But you are “eating” every 3 hours or so (drinking a shake).
The other 50% report being so full that they have a hard time drinking all the shakes for that day. Look around in the Ask Chris forum and you’ll see dozens of these. Not a bad problem to have when on an extreme fat loss diet, but some people find it to be trouble.
So, it’s a toss-up: you may be hungry at times, or you may be so full you’ll want to skip shakes (which isn’t recommended.)
As for strength, some report increases, some report temporary losses then a quick rebound once more normal eating resumes. As excess fat is dropped, people typically perform better, jump higher, do more chin-ups, dips and push-ups etc. Bench press could go down, but if that’s because the ROM is longer since two inches of fat has been peeled off the chest and back, then that’s not really “strength” loss.
Anyway, the primary focus of the V-Diet is rapid, extreme fat loss, and the accompanying reprogramming of dietary habits. That has to be the focus for at least the 4 week strict phase. Every other goal needs to be set aside for 28 days.
Hope that helps.
