Health wise I mean. Have read up about all of them, and am going to start this weekend with DH, but not sure which is healthiest - south beach seems OK, but has low fat stuff in too (bleeurrch), India seems OK, but am V put off by the truck load of supplements she insists on - all together they seem way in excess of the RDA, and she insists they be taken forever, which is flipping expensive-can anyone with a nutritional background shed any light? Would love to hear anyone's opinion on this.
