Honestly? Neither one. NOOM is in hot water with the BBB for overcharging and continuing to charge people after they've dropped their subscription. GOLO? Any plan that has you taking THEIR supplements as a part of the plan should send you running.
You don't need a "weight reduction" or "diet" plan. You need to make a lifestyle change. Move more. Eat less. Don't eat ******. If you're determined to pay for something, look in to a lifetime subscription to Lose It. I think it's right around $100.
