DIET and NUTRITION

The Slim Fast 321 Plan is a straightforward diet that encourages eating six portioned meals or snacks throughout the day.

Slim Fast is widely recognized for its line of meal replacement shakes and bars and this diet recommends eating two or more of these products every day.

Slim Fast shakes and bars are high in protein and fiber.

Here is a typical day on the Slim Fast 321 Plan:

  • Breakfast: One Slim Fast 321 Shake or a Slim Fast Bar
  • Snack: One-half of a banana, one pear or one Slim Fast 100-calorie Snack Bar
  • Lunch: One Slim Fast 321 Shake or a Slim Fast Bar
  • Snack: One medium apple, one cup of strawberries or one Slim Fast 100-calorie Snack Bar
  • Dinner: Grilled halibut with veggies, fish tacos, Asian beef salad
  • Snack: Two medium apricots or one Slim Fast 100-calorie Snack Bar

A two-week sample menu plan is included on the website as are portion guides for your one daily meal and sample meal ideas.

EXERCISE

Exercise is an integral part of the Slim Fast 321 Plan. Regular exercise not just improves weight loss outcomes but it also contributes to overall wellness.

On the plan, you are encouraged to exercise on most days of the week, doing a combination of cardiovascular and strength-training exercises.

You can track your exercise progress on your online progress calendar.

CONCLUSION

The Slim Fast 321 plan is not as easy as 1-2-3, but it is a straightforward diet that requires you adhere to the frequenting noshing of Slim Fast products and the characteristic "sensible meal."

While this plan gets high remarks for its structure and encouragement of portion control, it falls short on variety and its reliance on fruit. Therefore, for those who are diabetic, you should talk to your doctor before starting this plan.

You definitely have to exercise with it but its been one week, and i have lost 1 inch around my waist and 5 lbs. (keep in mind i never exercised and ate whatever i wanted, and i smoked.) I no longer smoke, I eat healthy, exercise for 30 min everyday, and i swear by slim fast 321 plan!

Although working at Subway might help a bit, I've actually lost about 25 pounds since I started this diet last month (Feb. 23rd, 2011)

I just have to say: it's wonderful.
It's easy to stay on, and you can find many meal choices under 500 calories.

Thanks, Slim Fast
You rock!
*thumbs up*

I went on Slimfast years ago after I gained 30lbs when I quit smoking. I lost 30lbs in 3 months. I found the diet convenient (you just throw your lunch into your bag and go). It can get a bit boring, but by the time that happens your pants are loose and that keeps you going. I'm older now and don't expect the same results I had then (I've got thyroid problems now), but I'm game for trying. WW didn't help me at all and I really stuck to it. Wish me luck!

I started the 3-2-1 plan on Friday.. I weighed in Friday morning & weighed 189.8 & this morning (Sunday) I weighed in at 185.4.. That's 4.4 lbs in 2 days!!! & I havent even worked out.. I'm gonna start working out & hopefully lose even more.. This plan works GREAT! I replace breakfast & lunch with a shake .. & for my snacks I eat the 100 calorie packs (so I can get in my sugar & salt cravings without messing up my progress) & dinner I have just been making whatever stays right around 500 calories.. I have also been drinking a LOT of water

I started this diet 7 days ago and have lost 6 pounds. No exercise. Lots of water. I am alot over weight so that may be why I lost so much in a week.

I have tried for ten years to lose even a couple of pounds with no success. Really. I didn't want to join a dieting group plan and I didn't want to keep track of points and I didn't want to buy meals. I bought two 6 packs of Slim Fast and in two weeks I lost 3 pounds. All I have done is eat a regular breakfast and lunch, and have a Slim Fast for dinner. Period. I am not hungry. Now, it has been a month and I've lost 7 pounds. HOORAY!

I am adding the slim fast into my diet because my wife didn't want to finish her's. But I do get up early and run for 2 miles or 30 mins before work everyday. Plus I'm putting the Insanity workout along with it. My goal is a 35 lbs loss. I drink the slim drinks , and or bars along with three other small meals no bigger than my fist. I'll keep an update weekly. Everyone keep it up!!

I'm due for my first weigh in on Wednesday, up to now i've found the plan easy to follow. At the moment Boot's have slimfast powder on special at half price so I've stocked up. I feel much better in myself, more energy and get up and go.

I 'm on day 1 and I like it! I'm not naive about the fact that it isn't a long term plan AT ALL! However, I think it's a great plan for ladies who wanna drop some holiday pounds, and ease into a more long term eating plan. I'm using the website and it's really awesome that they give you options that aren't all Slim Fast products! I have my ending date as the middle of July so I think it's a good plan for a month or two but nothing more!
