Not really the forum, but... you lose weight when you eat fewer calories than you burn in the day, you gain weight when you eat more calories than you burn. I don't know exactly what snacks you are proposing, but it sounds like you are proposing eating very little food and so a big calorie deficit. If you could stick to the diet the weight would probably fly off, but it does sound unhealthy to me.
People generally say that when you are in calorie deficit, it is very hard to get stronger, and odds on the best you will be able to do is maintain your current strength. Not everyone finds this, but a lot do. That being said, the deficit you are proposing sounds big... it might make it really hard.
I don't know much about diet, but since this is the Strength and Power forum, why don't we ask Glenn Pendlay?
Lessons from Glenn Pendlay
What he is saying is roughly my diet: heavy on meat, veg, salad, milk, eggs, nuts, quite a bit of fruit for snacks. When trying to lose weight, I ban pasta, bread, potatoes and rice except for one cheat meal a week. When trying to gain strength/weight, I eat pasta, bread, potatoes and rice, but still not as much as the other stuff.
Anyway... you'd be well advised to do some research on this.
